Light alloy, aluminum alloy as a kind of excellent properties in recent years in our country industry get promoted.Due to the different physical and chemical characteristics of aluminum alloy steel and other traditional industrial materials, under the condition of the traditional manufacturing technology, the use of aluminum alloy has some bottlenecks.Only through technology innovation and revolution, to break through the bottleneck, to the excellent performance of aluminum alloy to shine in various industrial fields.
Connection technology is one of the bottlenecks in the process of aluminum alloy processing and manufacturing.Traditional connection technology including riveting and welding, and the two ways for aluminum alloy, respectively obvious shortcomings in terms of efficiency and performance.How to adopt a way of connection, not only has high efficiency, but also has high performance, at the same time can both environmental protection and green manufacturing?It was like to describe a perfect technology, and actually really exist?
Friction stir welding, for most people, the term is also very strange.Friction stir welding as a kind of automatic solid connection technology, overcome the low efficiency and poor sealing of the problems of riveting, has also changed the welding for aluminum alloy "water" and the operator of the occupational health problems.The technique was only 20 years, but in the world within the scope of all kinds of industrial applications has made brilliant achievements.
Five major advantages
Friction stir welding is developing rapidly
Friction stir welding as a kind of connection method of solid phase is based on the numerical control machine tool mode of a kind of welding way, both operational, or accuracy, and have not substitute technology in such aspects as environmental pollution-free advantages.
First of all, the friction stir welding technology is implemented under the plastic state of materials, products with high weld metallographic consistency and weld hot cracking, welding defects such as inclusions, porosity.
Second, friction stir welding technology using automated machinery and equipment for welding, to avoid the dependence on operating workers technical proficiency, for all position welding automation, improve work efficiency.
Third, friction stir welding technology without having to treat the welding products for special treatment, do not need to open groove, filling materials and protective gas, the welding process is simplified.
Fourth, friction stir welding process does not produce dust, spatter, ultraviolet radiation and electromagnetic radiation, to realize the welding process of green, environmental protection and harmless.
Fifth, friction stir welding of weld residual stress is low, basic no deformation, weld properties close to the parent metal, mechanical performance, improve the reliability of the weld.
In Europe, friction stir welding applied in shipbuilding industry, the earliest ship for manufacturing aluminum alloy, aluminum alloy panel welding problem, need to be solved before welding welding way prone to "thin horse phenomenon" (hull structure in the process of welding, will produce certain deformation, especially the plate and the superstructure, welding deformation especially, commonly known as "thin horse phenomenon"), the phenomenon not only cause the loss of hull surface beautiful degree, but also can not meet the requirements, the material strength indexes and the application of friction stir welding to solve the problem.So, before the introduction of friction stir welding in China, has been manufacturing aluminum boat, until Beijing FSW technology co., LTD., for the first time in a certain type of missile speedboats scale application of friction stir welding technology, the notion of the over China cannot make aluminum boat.At present, the friction stir welding technology has been widely used on naval ships and yachts.Can say, because of the friction stir welding technology, the application of aluminum alloy in the field of ship to expand.

Aluminium Flanges
Aluminium flanges offer superior corrosion resistance, making them ideal for environments prone to moisture or chemical exposure, such as marine, chemical processing, and wastewater treatment facilities. Compared to steel or iron flanges, aluminium ones have a longer lifespan and ensure reliable performance in challenging conditions. Their resistance to rust and corrosion significantly extends their lifespan in harsh environments, making them the preferred choice for applications exposed to moisture or chemicals.
Aluminium flanges stand out as one of the more weldable components, enabling seamless integration into pipe systems through welding processes. Aluminum's inherent properties enable strong and secure welds which seal leak-free connections between components - an attribute which also simplifies installation and maintenance tasks by permitting quick repairs without undermining structural integrity.
Aluminium flanges offer many practical advantages beyond their technical properties, including reduced overall system weight for easier handling and installation as well as cost savings compared to alternatives such as stainless steel that won't compromise performance or durability.
Aluminium flanges find applications across several industries where lightweight, corrosion-resistant, weldable piping components are necessary, including aerospace, automotive, pharmaceuticals, food and beverage processing and renewable energy sectors. Aluminium flanges can be found in aircraft fuel systems, hydraulic systems and air conditioning units due to their light construction that resists aviation fuel and hydraulic fluid. In aerospace applications specifically they may even be utilized with aircraft hydraulic fuel injection systems owing to resistance properties of aviation fuels and hydraulic fluids that they provide resistance from.
Aluminium flanges find diverse uses across industries, providing critical functions in fluid handling and transmission systems. Automobile manufacturing utilizes them extensively in cooling systems, exhaust systems and fuel delivery systems due to their lightweight design and corrosion resistance; pharmaceutical and food processing industries make use of aluminium flanges in fluid transfer for product purity and quality maintenance; they're even integral parts of renewable energy applications like solar or wind power generation where corrosion resistance and durability play key roles for long-term performance.

Ultra-high-strength aircraft aluminum sheet generally refers to aluminum alloys with a a yield strength of more than 500MPa, and the most common ones are ultra-duraluminum 7000 series. This series of aluminum alloys was originally developed under the background of aerospace applications, and has now developed into the main structural materials of military and civil aircraft in the world, accounting for 70-80% of aircraft structural parts.As a relatively mature lightweight high-strength alloy material, aluminum alloy is widely used in aerospace. Aluminum alloy materials like 7075 aluminum plate are generally used as structural materials, which have higher specific strength and better processing performance than steel.The aerospace field mainly develops high-strength, high-toughness and strong corrosion-resistant aluminum alloy materials to meet the harsh conditions of use in aerospace. The most widely used are 2000 series and 7000 series. The main components of 2000 series aluminum alloys are mainly aluminum (Al), copper (Cu), and magnesium (Mg). The main components of 7000-series aluminum alloys are Al, zinc (Zn), Mg, and Cu elements.The 2000 series aluminum alloy mainly uses Cu as the main alloying element. The alloy prepared by adding an appropriate amount of Cu element to the aluminum alloy material will have a better improvement in strength, heat resistance, and processing performance, but the corrosion resistance will decrease.Therefore, for 2000 series aluminum alloys like 2024 aluminum sheet, pure aluminum or 6000 series aluminum alloys are generally coated on their surface as an electrochemical protective film to improve their corrosion resistance.Generally speaking, the development direction of aluminum alloy is from high strength, low toughness to high strength, high toughness, and then to high strength, high toughness, and corrosion resistance. The development of heat treatment state develops from T6 to T73 to T76 to T736 to T77.The degree of alloying is getting higher and higher, the content of impurities such as Fe and Si is getting lower and lower, and the addition of trace transition elements is becoming more and more reasonable, and finally the overall performance of the alloy is comprehensively improved.

As we all know, the CTP digital printing has brought many benefits to printing: excellent image quality, near perfect calibration, and fast production turnaround. However, its various advantages are not only attributed to the imaging equipment, but also depend on the quality and performance of the CTP plate.Now in the CTP market, the three CTP technologies with the largest sales volume are silver salt, thermal and violet laser. The printing plates produced by these technologies are silver salt, thermal and violet CTP plates.The CTP plate consists of a plate base and a photosensitive layer. The plate base treatment generally includes the following processes: degreasing, electrolysis, ash removal, oxidation, sealing, etc. Among them, the sealing has a crucial influence on the performance of the CTP plate.Sealing directly affects the sensitivity of the CTP plate, the printing durability and the balance of ink and water in the printing process. And the degree of sealing is not easy to control, if it is too high, the printing durability will be low, and if it is too low, the sensitivity will decrease.In the requirements of the PS plate, the surface roughness Ra value is 0.3 μm, which is not enough for the CTP plate, because the Ra value of the grain roughness of the CTP plate is only 0.5 μm to 0.6 μm. The Ra value of the surface of the aluminum plate base for the manufacture of CTP plates is preferably around 0.2 μm.The thickness of the aluminum plate base for CTP plates is generally 0.280mm, which is slightly thicker than the PS plate currently produced (the thickness of the PS plate base is 0.270mm±0.005mm). Some foreign companies also use 0.275mm thick aluminum plate base, and the thickness tolerance is ±0.005mm. The thicker the aluminum plate, the better the stiffness of the plate.Aluminum plate for making CTP plate should be clean and smooth. It can’t have cracks, corrosion, vent holes, severe abrasions, scratches, marks, peeling, oil marks,etc. Defects such as non-metallic pressing, slight color difference, bright stripes and other problems are not allowed.Haomei Aluminum has different types of printing plates including PS plate, CTP plate and CTCP plate. Our thermal ctp plate is very favored by the global customers. Welcome to inquire thermal CTP plate price.

When aluminum foil is used in food packaging, it has the functions of preserving fragrance, color, taste and quality, which mainly depends on the characteristics of aluminum foil such as high barrier property, light resistance, high temperature resistance, low temperature resistance, oil resistance, water resistance,etc. Because of these almost perfect advantages, it is very popular in the food packaging industry.At present, container aluminum foil that can be heat-sealed and sterilized by high temperature and high pressure are also widely used in pies, luncheon meat, cans, sauces, jams, processed cheese, coffee milk, vegetarian paste and other products that require a long shelf life.Although it has so many advantages, the high price restricts the development of aluminum foil. Taking aluminum food tray for example. The price of a 20-gram aluminum foil container on the market is about 0.75 RMB, the recycling price is 0.2 RMB, and the actual use cost is about 0.55 RMB. However, the cost of foamed plastic container is less than 0.1 RMB. Therefore, the competitive advantage of aluminum foil packaging in food packaging is mainly concentrated in the middle and high-end food, and the fields that require relatively high heat resistance.The alloys of aluminum foil for food container are 3003, 3004, 8011, 8006, 5052,etc. Most of the early domestic aluminum container used 3003 plain aluminum foil. Later, in order to reduce costs, 8011 alloys also began to be used in aluminum foil tray. 3004 aluminum foil has high hardness and good load-bearing. The stamping effect is better than 3003 aluminum foil. It can be applied to aluminum foil tray.Haomei plain aluminum foil is clean, free of oil stains, bright lines and other inclusions. The products have undergone strict void detection, degreasing process and plate shape control. The hygiene meets food-grade requirements and has a high elongation rate.

The conventional thickness of aluminum diamond tread plate is 0.5mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm, 6mm. The cheap one is 1060 5 bar aluminum tread plate, but for special places requiring high strength or high corrosion resistance, 5052 or 6061 aluminum plate are a better choice, which has excellent corrosion resistance.For places that are suspended in the air and need to be stepped on by staff, it is recommended to use alloy series, and the thickness is not less than 1/4 inch. The common choice is: 4x8 sheet of 1/4 inch aluminum. This series and thickness can ensure the safety of the staff to the greatest extent, and at the same time ensure the service life of the aluminum tread plate.Patterns5bar aluminum tread plate is cheap and has good anti-skid effect. It is divided into large 5 bar and small 5 bar. The pattern length of the big 5 bar is about 42mm while the length of the small 5 bar is about 35 mm. The height of the pattern is about 0.8 mm.Aluminum tread plate priceThe unit price of aluminum tread plate =aluminum ingot price + processing fee. The processing fee of aluminum plate of different alloys is different. When we buy the patterned aluminum plate, we must first figure out the material of the patterned aluminum plate. The performance of the patterned aluminum plate is different with different materials.Applications1. As a transportation facility for vertical traffic and urgent evacuation of people, stairs have a large flow of people and steep slopes, which are prone to danger in use. Therefore, it is necessary to use aluminum diamond plate.2. We can often see the aluminum diamond tread plate at the bottom of the car when we take the bus.

4x8 aluminum sheet refers to 4 foot and 8 foot, a ratio of the width to length of the aluminum sheet. 1 foot = 304.8 mm, 4′ = 1219 mm, 8’ = 2438 mm. Thus , it means the size of 4x8 aluminum sheet is 1219 mmx2438 mm.4x8 aluminum sheet has no restrictions on the alloy. It is a common size for most aluminum alloy sheets like pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium-thick aluminum plate, tread aluminum plate. Alloys include 1050, 3003, 3105, 3004, 5005, 5052, 5083, 5754, 6061, 7075,etc.3mm 4x8 aluminium sheet is very common in shipbuilding. Commonly used alloy grades are 5083, 5086, 5052 and 5754, 3003, 6061, etc. These aluminum sheets for marine use are lightweight and offer excellent corrosion resistance, machinability, formability, weldability, and more. They are used for boat decks/sides/bottoms/outboards, etc.The 6061 aluminum plate belongs to the 6000 series, and the alloying elements are magnesium and silicon. The production has gone through a series of complex processes, from semi-continuous ingot casting, homogenization, sawing,surface milling, aluminum cladding, heating, hot rolling, annealing, cold rolling, annealing, cold rolling, solution treatment, aging treatment to cutting, leveling, inspection, oiling and packaging.These processes are the basic processing steps of 6061 aluminum alloy. Since the processing of 6061 aluminum plate is more complicated than that of most alloy aluminum plates, the processing cost of 6061 aluminum plate is higher.3003 aluminum sheet metal is an aluminum-manganese plate. Due to the addition of manganese element, the hardness and strength of 3003 aluminum plate are about 10% higher than that of 1100 aluminum plate and 1060 aluminum plate. Due to its good corrosion resistance, 3003 aluminum sheets are widely used in shipbuilding, and can be used to manufacture interior decoration parts and heat insulation and sound insulation materials for warehouses.

Air fryer aluminum foil is also a kind of household aluminum foil. It is used for wrap food in air fryer like vegetable, fish and biscuits. The common alloys are 1060, 3003, 8011,etc. It can be divided into single-sided shiny foil and double-sided shiny foil.Aluminum foil rolling is divided into single-sheet rolling and double-rolling. During single-sheet rolling process, both sides of the aluminum foil are in contact with the roll surface, and both sides have bright metallic luster, which is called double-sided shiny foil. During double rolling, only one side of each foil is in contact with the roll, the side that is in contact with the roll is bright, and the other side is dull.The air fryer aluminum foil can be used as the paper pad for the baking tray, which is used to avoid direct contact between the baking tray and the food. Firstly, it prevents the food from sticking to the baking tray; secondly, it isolates the bacteria on the baking tray, which is more hygienic. And it saves the trouble of cleaning the baking pan.It is also often used to help bake bread. If the food is directly baked in the air fryer, it is prone to uneven heating and slow heating. And if the food is wrapped in aluminum foil and then baked, the heat source of the air fryer will be transmitted to the aluminum foil and then to the food, so that the airtight interlayer between the food and the aluminum foil will generate water vapor and hot air, which can not only heat the food evenly, but also speed up the heating.The household aluminum foil roll is is made of primary aluminum alloy and rolled through multiple processes, and it does not contain harmful substances such as heavy metals. In the production process of aluminum foil, a high-temperature annealing sterilization process is adopted, so the aluminum foil can be safely in contact with food and will not contain or promote the growth of bacteria. In most cases, aluminum foil will not react with food.
