One of the most useful characteristics of aluminium is its formability, and one way to form the metal into the shape you want is through bending. There are three influencing factors: formability, thickness and bend radius, and elongation.Recently there are many customers who ask about aluminum bending. For example, what is the bending radius of 5mm aluminium plate? Which knife should be used? And why does the aluminum sheet crack during bending?In fact, the bending radius of aluminum plate can be calculated. It is usually 0.8 times the thickness of the aluminum plate. So the bending radius of 3mm aluminum sheet is 2.4 while that of 5 mm aluminium sheet is 4. If you use a knife, it is generally better to use a sharp knife.There are some causes of cracking when the aluminum sheet is bent 180 degrees:1. The bent side is parallel to the rolling direction of the aluminum plate, so it is easy to crack. Turn the bending direction 90 degrees. 2. The 180 degree bending angle is too much, which is larger than the minimum bending radius. Generally, the bending radius is 1.5 times of the aluminum plate thickness. 3. It is because of the alloys. Some alloys are easy to bend such as 3003 and 6061. For each different alloy, we should choose right temper. The 3003 aluminum sheet with O temper is better for bending.4. The aluminum plate is too thick, which exceeding the bending limit of the material.As a big aluminum sheet manufacturer, Haomei Aluminum has different thicknesses of aluminum sheets. Welcome to inquire 5mm aluminium sheet price directly.

Air conditioner has been irreplaceable no matter in summer or winter. For reaching cooling or warming effect, we need the heat exchanger, an important part of the air conditioner. Air conditioner foil is a special material for manufacturing air conditioner heat exchanger fins.The development of aluminum foil for conditioner is accompanied by the development of air conditioner demand. The aluminum foil used early in the air conditioner is plain aluminum foil. In order to improve the surface performance of the air conditioner foil, a certain coating is applied on the surface of the aluminum foil. The aluminum foil with hydrophilic coating is called hydrophilic aluminum foil.In order to improve the performance of air conditioner foil, the aluminum foil manufacturers in different countries are conducting technical research. In China, the air conditioner foil alloys have also roughly gone through the development process of 1060, 1050, 1100, 1200, 3102, 8011 and other alloy grades.The speed of the air conditioner fin forming equipment has been continuously improved, which has been increased from 200 times/min to 350 times/min or even 450 times/min. Each feeding is increased from 50mm/2 holes to 100mm/4 holes. This certainly put forward higher requirements for the mechanical properties, straightness and thickness uniformity of the aluminum foil.There are two production methods for air conditioner aluminum foil: one is the cast-rolled and the other is hot-rolled. These two methods have their own advantages. By developing homogenized annealing process for the cast rolled aluminum foil, the mechanical properties of air conditioning foils have been greatly improved.

Air conditioner foil is an important aluminum fin stock material. It has the advantages of good shaping, good coating performance, high coating adhesion, good hydrophilicity and good corrosion resistance. The common alloys are 1100,1200, 3102 and 8011,etc.There are two processing crafts for the converter foil:1. Ingot- homogenization annealing- hot rolling- cold rolling- trimming- cold rolling- box rolling- slitting- finished product annealing - packaging2. Casting and rolling- cold rolling- trimming- cold rolling- box rolling- slitting- finished product annealing- packagingDuring the hot rolling process, the aluminum ingot produced by the DC casting method is hot-rolled into a strip of 2.0-10.0mm, and then cold-rolled and foil-rolled. The crystal structure of the ingot is composed of quenched structure of the outer layer and the columnar crystal and the equiaxed crystal structure in the central part.The cast rolling has the characteristics of rapid solidification and directional crystallization. Its crystalline structure consists of columnar crystals on the surface and equiaxed crystal structure in the center.Due to the rapid cooling characteristics of twin-roll casting, the internal grains of the cast-rolled strip are greatly refined, and the supersaturation of alloy elements such as Mn, Fe, Cr are achieved. And the particle size of the intermetallic compound is smaller, about Only 1/5 of hot rolled billet.The difference in structure results in that under the same rolling and annealing conditions, the aluminum foil of the cast-rolled billet has higher strength and lower elongation than that of the hot-rolled billet. At the same time, the cast-rolled billet also has a relatively high working speed.However, with the continuous advancement of aluminum processing technology and the development of new alloy materials, the current air conditioner aluminum foil by the cast-rolling method has been able to fully meet the performance requirements of various air-conditioning cooling fin forming processes.At present, the air conditioner foil produced by cast rolling has been the mainstream product on the market. As a big aluminum foil producer, Haomei Aluminum can offer you both hot rolled or cast rolled aluminum foil.

Aluminum is of oft texture and good ductility. It can be rolled to obtain aluminum foil, which is often used for packaging material, air conditioner, foil tape, cap material,etc. Air conditioner foil is one of its man kind.Air conditioner foil is used as the raw material of the heat-conducting fin for the air conditioner radiator. It has the advantages of small density, good thermal conductivity, easy processing, no odor, environmental protection and low price.Aluminum foil has been used in the production of air conditioner at home for more than 20 years and get rapid development in the pat 10 years. With the rapidly spread of the use of air conditioner year by year, the demand for aluminum foil for air conditioners is also rising.As a professional aluminum foil producer, Haomei Aluminum has two processing methods for air conditioner aluminum foil:Casting and rolling- cold rolling- trimming- cold rolling- box rolling- slitting- finished product annealing- packagingIngot- homogenization annealing- hot rolling- cold rolling- trimming- cold rolling- box rolling- slitting- finished product annealing- packagingAt present, the common air conditioner foils are 3102 and 8011 aluminum foil for sale. The common tempers are H22/H24/H26, and the thickness range is 0.08-0.2 mm. There are certain differences in strength and plasticity in each temper. As for which alloy and temper of aluminum foil to choose, it depends on the actual situation.

The annealing process is the most critical process to control the temper of air conditioner aluminum foil. The cold-deformed structure is work hardened, and as the temperature increases during annealing, recovery and recrystallization will occur.When the heating temperature is low, the cold deformation mainly recovers, and the recovery process appears as a polygonal process. A sub-crystalline structure is formed. With the increase of temperature and time, the size of the sub-crystal gradually increases, and the dislocation entanglement gradually disappears.A sharp sub-grain boundary appears. Then as the temperature increases and the time increases, some the subcrystals coarsen to form the recrystallization core until recrystallization. For the aluminum foil for air conditioner with H22 temper after annealing, it should be composed of deformed fiber structure and a large number of fine, uniform, and dispersed recrystallized crystal nuclei.For 8011 aluminum foil for sale, annealing is generally carried out at about 290℃. If the raw material for annealing has not been cleaned, it is necessary to add a degreasing section before annealing to ensure that there is no oil spot on the surface of the finished aluminum foil.Annealing time depends on factors such as furnace load, product thickness, furnace temperature distribution uniformity, and annealing furnace thermal efficiency. Generally, if these conditions are not ideal, the annealing and holding time should be extended, but the holding time in the furnace should not exceed the time required for all the loaded products to reach the annealing temperature.

Aluminum strip stock can be divided into many series according to different alloys. There are some common series. Lets have a look together.Pure aluminum strip: The pure aluminum strip is one kind of the soft aluminum strips. The advantage of pure aluminum tape is that it has good thermal conductivity, electrical conductivity, and good ductility. It is often used in transformers, cable armoring, metal stamping, lampshades, radiator fins, etc.In the H24 semi-hard temper, the pure aluminum strip has good bending and stamping performance, and the tensile performance in the O temper is very good. It is suitable for the processing of the forming parts by stretching such as lamps and lanterns. At the same time, the pure aluminum strip price is the lowest among all the alloys.Al-Mn aluminum strip roll: The typical alloy is 3003 aluminum strip. It is of a certain strength and excellent rust and corrosion resistance, therefore it is suitable for the processing of hardware products with certain requirements for strength. The 3000 aluminum strip price is slightly higher than pure aluminum strip.Al-Mg aluminum strip stock: Its representative alloys are 5052 and 5754 aluminum strip, which have a relatively high content of magnesium. They are of high hardness and good bending performance, which is suitable for the hardware industry that has the clear requirements for hardness and bending performance.Al-Mg-Si aluminum strip: The most popular alloy in this series is 6061 aluminum strip with T6 temper. It is one of the highest hardness products among all aluminum strips, which is not suitable for bending.Each series of aluminum alloy strip has its application. What do you use aluminum strip for? As a big aluminum strip roll supplier, we have different alloys, different sizes and different processing craft, welcome to leave message below to get what you want.

In order to the oil stains on the surface of the aluminum strip during the production process, we can choose to add a cleaning process. However, if some manufacturers does not have professional equipment, it is not recommend to clean the aluminum bendable strips.Haomei Aluminum chooses a neutral liquid to do the cleaning to avoid the corrosion of the soft aluminum strips. At the same time, drying treatment will be carried out after cleaning to avoid oxidation of the aluminum strip.By using a wrong clean method, it will cause the following hazards to the bendable aluminum strips:It will cause damage to the surface of the aluminum strip after friction. If a relatively uneven tool is used to clean the aluminum strip stock, the surface of the aluminum strip is prone to friction grease in the repeated cleaning process. The scratches will directly affect the surface quality of the soft aluminum strips.It will lead to the corrosion of the bendable aluminum strip. If a strong acid or alkali cleaning agent is used to replace the neutral cleaning agent when cleaning the aluminum strip, it is easy to cause corrosion damage to the aluminium strips. In addition, if it cannot be dried after washing, the aluminum strip will change color.It is likely to reduce the service life of the aluminum strip. As improper cleaning will cause damage to the aluminum plate, the service life of the aluminum strip will be shortened to a certain extent. Therefore, we must ensure the right cleaning process and tools.As an experienced aluminum strip roll supplier, we suggest that the professional aluminum cleaning agents can be used to remove black oxide spots, rust spots, mold spots, carbonate deposits, mechanical particles, oil stains, stamping oil stains, fingerprints, and aluminum slag on the surface of aluminum strips.

As a downstream processing enterprise of aluminum bendable strip, if you want to get a quality product, the quality of the raw materials is very important. How to check the quality of the aluminum bendable strip? There are four factors to help us to make judgement.1. The chemical elements of aluminum strip. The content of various alloying elements in the soft aluminum strip plays a vital role in the performance of the aluminum strip. The increase or decrease of the content standard will affect the mechanical properties of the aluminum strip. So the chemical composition content of the aluminium strip is one of our judging standards.2. The dimensional tolerances of aluminum strip. We mainly look at the dimensional tolerances of aluminum strips, such as thickness, length and width, diagonal and flatness. If the bendable aluminum strip does not meet the standard, it will affect the further processing.3. The mechanical properties of aluminum strip. The mechanical properties of the soft aluminum strip include tensile strength, yield strength, elongation, hardness, etc. These indicators are what we need to pay attention to. If they are not properly controlled, they will also affect the subsequent processing.4. The surface quality of the aluminum strip. In the factory, if the aluminum strip is not carefully produced, it is easy to cause scratches, scratches, abrasions, etc., and it will also cause emulsion marks and macula due to pollution. These surface quality problems are not conducive to the following processing. It may affect the use of the product, not to mention that the surface of aluminum strip is not beautiful.As a big aluminum strip roll supplier and manufacturer, Haomei Aluminum has always had a strict control of the aluminum strip stock, therefore we has won many customers’ trust worldwide. Sample test is supported.

In recent years, Apple mobile phones have been the industry benchmark, leading the trend of mobile phone development.Apple has been using an all-aluminum alloy body since the iPhone 5, because of its light weight, high temperature resistance and gorgeous metallic luster. In addition, aluminum alloy is easier to recycle, which is more in line with the contemporary environmental protectioniPhone 6 is the last generation version of the Iphone6s in 2016 and was released in September 2014. The iPhone 6 uses the 6000 series aircraft aluminum sheet , but due to the insufficient strength of the 6000 series alloy, it is easy to bend. Therefore, the iPhone 7 uses the higher-grade 7 series aluminum alloy.The 7 series aluminum alloy is mainly made of zinc, and a small amount of magnesium and copper are added. The hardness of the aluminum alloy is closer to the hardness of the steel, which means that the iPhone 7's shell is less likely to bend, and the shell is more rigid.The specific aluminum alloy is 7075 aluminum plate. It is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one most powerful alloys commercially available. Among this series, the 7075-T651 aluminum alloy is especially the top grade. It is known as the best product among the aluminum alloys.It has high strength and far better than any mild steel. This alloy also has good mechanical properties and anodizing reaction. It has been used for the smart phone shell of OPPO N3 for the first time in 2014. Now more and more smart phone manufacturers choose 7075 as the phone shell. If you like to find a reliable 7075 aluminum plate supplier, welcome to leave message below.
