<p>
Since February of this year, China <strong>aluminum wholesale prices</strong> have gone out of the extremely strong “V”-shaped reversal market after experiencing a panic-stricken decline caused by the new coronary pneumonia epidemic. On July 10, the main contract of Shanghai Aluminum closed at 14,375 yuan/ton, a new high for the year; it was 3,120 yuan/ton higher than the lowest point of 11,255 yuan/ton on April 2, up 27.7%. During the same period, Lum Aluminum also rebounded from a low level, closing on July 9 at 1659 US dollars/ton, up 16.5% from the low point of the year.<br></p>
<p>
This round of rises in <strong>wholesale aluminum sheets</strong> prices was driven by multiple factors. First, with the improvement of epidemic situation in China, domestic demand for <strong>aluminum plate</strong> sheets is reviving gradually; Second, the epidemic has led to a significant decline in domestic scrap aluminum recycling, while imports have continued to decline, and the supply of scrap aluminum was once tight, leading to the substitution of primary aluminum for scrap aluminum About 350,000 to 400,000 tons increased; Third, after the <strong>wholesale aluminum sheet metal</strong> price plunged at the end of March, the entire industry chain stored aluminum: upstream reluctant sales, active stocking by distributors, advance orders in the field of aluminum processing terminals, and large purchases of raw materials by processing companies; fourth, Explicit inventory quickly declined from a high of 1.68 million tons at the end of March to 710,000 tons on July 10, and there was a strong tension in spot supply. Fifth, abnormal speculation in the spot and futures markets appeared to contribute to the rise in aluminum prices.</p>
<p>
Will prices for wholesale aluminum sheets continue to rise in the near future? As the basic raw material, the price of aluminum should be stable, especially for large-demanded products like <strong>wholesale 5083 aluminum plate</strong> for shipbuilding. Historical experience tells us that after a big rise, there must be a big fall, and a suitable and relatively stable whole aluminium sheet metal price is conducive to the healthy development of the aluminum industry chain. Considering comprehensively the factors such as the cost of electrolytic aluminum, the profitability of each link of the industrial chain, downstream consumption and alternative competitiveness, combined with the historical trend of aluminum whole prices, and from the perspective of building a community of destiny in the aluminum industrial chain, we should strive to keep a suitable and relatively stable aluminium price. This will benefit both the suppliers and purchasers from abroad.</p>

<p>
Both the <strong>5052 aluminum plate </strong>and the <strong>5083 aluminum plate</strong> belong to the 5-series aluminum-magnesium alloy, but their magnesium contents are different, and other chemical components are also slightly different.</p>
<p>
Their chemical compositions are as follows:</p>
<p>
5052 Si 0+ Fe0.45 Cu0.1 Mn0.1 Mg2.2-2.8 Cr0.15-0.35 Zn 0.1</p>
<p>
5083 Si 0.4 Fe0.4 Cu0.1 Mn0.3-1.0 Mg4.0-4.9 Cr 0.05-0.25 Zn 0.25<br></p>
<p>
The differences in chemical compositions of the two result in their varied developments in mechanical performances. 5083 <strong>aluminum plate</strong> is much stronger than the 5052 aluminum plate in either tensile strength or yield strength. Different chemical substance compositions lead to different mechanical equipment performance, and different mechanical product properties also lead to different uses of the relationship between the two.</p>
<p>
5052 alloy aluminum plate has good forming processability, corrosion resistance, candleability, fatigue strength and moderate static strength. It is used to manufacture aircraft fuel tanks, fuel pipes, and sheet metal parts for transportation vehicles and ships, instruments, street lamp brackets and rivets, hardware products etc. Many manufacturers claim that 5052 is a <strong>marine grade aluminum plate</strong>. In fact, this is not accurate. The commonly used marine aluminum plate is 5083. The corrosion resistance of 5083 is stronger and it is more suitable for use in harsh environments. It is used for applications requiring high corrosion resistance, good weldability and medium strength, such as ships, automobiles and aircraft plate welded parts; pressure vessels, cooling devices, TV towers, drilling equipment, transportation equipment, missile components and so on.</p>

<p>
<strong>3.5mm aluminum sheet</strong> 5754 is a regularly thick aluminium plate. Aluminium plates fall on five groups divided by thickness: thin sheets (below 2mm thick), regular sheets (2mm-6mm), medium sheets (6mm-25mm), thick sheets (25mm to 200mm) and super thick sheets (200mm-600mm). Most founderies supply only those below 450mm thick. 3.5mm aluminum sheet, among the most frequently applied thickness group, covers a vast scope of alloys and finds its applications in vehicles, marine building, electric products, furniture, exterior decoration, interior decoration and so on.<br></p>
<p>
<strong>5754 aluminum sheet</strong> has magnesium as the main alloying element. It is in medium to high strength, has good fatigue performance and welding performance, and is resistant to marine atmospheric corrosion. 5754 aluminum alloy sheets with different heat treatment status are the main materials used in automobile manufacturing (car doors, molds, seals) and can manufacturing industries. The surface of Haomei 3.5mm aluminum sheet 5754 is smooth, without cracks, corrosion spots or traces of nitrate. As a product of regular thickness, 5754 3.5mm aluminium sheet can be made into patterned aluminum plate, embossed aluminum plate, pre painted aluminium sheets, anodized aluminum sheet, and mirror finish aluminum sheet.</p>
<p>

<p>
A <strong>10mm thick aluminum circle</strong> is a die-casting aluminium flat sheet product. Regular thickness for aluminum circles is from 0.6mm to 5mm. Thus aluminium circles with a thickness of 10mm exceeds the regular specification scope. And discs of over 8mm thick are more expensive than those below 8mm, for their production entails hot rolling which involves extra cost in energy and material.<br></p>
<p>
There are three processing methods for aluminum circles: stretching, die casting and anodizing, and die casting circles fall on the the thicker group of the three. They serve as raw materials for heavy soup pots, kettles, cookers and baking trays. Alloys for 10mm thick die casting aluminum circle include 3003, 1100, 1060, 1070 and 5052. Diameter ranges between 30mm to 1200mm. Usually the circles are hot rolled rather than cast rolled, thus the price is more expensive than thinner ones.</p>
<p>
<strong>Aluminum circle suppliers</strong> usually have 10mm thick aluminium circles mill finished or anodized. Most of the circles will be further compounded with other metal pieces before becoming a thick cooking tool. Owing to its extraordinary thickness, 10mm round sheets are rarely in stock, unless we happen to have some stock from a previous order. If you need thick aluminium discs, please do not hesitate to contact us!</p>

<p>
The process method for aluminium circle falls on three types: stretch, die-casting and anodizing, and <strong>aluminum circle pressure cooker</strong> is obtained by die-casting. By thickness it belongs to the thick type, more suitable for boiling soup for a long time. Pressure cooker aluminium circles are slower in heat conductivity, for they contain numerous micro holes in the inner structure.<br></p>
<p>
By alloy types there are pure industrial aluminium circles and alloyed aluminum disc circles. Industrial ones include 1050, 1060, 1070 and 1100, which are not fitted to be made into high pressure cookers owing to weak hardness and corrosion resistance. Alloyed circles, incorporating 3003, 5052, 3004 and 6061, prove to be appropriate materials for pressure cookers. Thickness for these circles ranges between 1.0mm and 5.0mm, and tempers cover O, H22, H24 and H18. The most popular among these are 3000 and 5000 series of circles featured by proper hardness, tensile strength and erosion resistance. In particular, 5052 aluminum circle shows excellent anodizing effect. The anodized aluminium circle discs are coated with an anodizing film keeping the aluminium icons away from possible access to elements in the food.</p>
<p>
Pressure cooker <strong>aluminium circle price</strong> is a little higher than that for regular industrial circles, ranging from $2300 to $2600 per metric ton. Usually the circles are anodized or coated. The hard anodizing film and coating cover are durable and safe, greatly enlarges the application scope of aluminum circle pressure cooker. As an aluminium disc circle supplier, Haomei overshadows other alu circle suppliers in strict quality control and high precision of raw materials. We adopt superior aluminum circle blanks and highly automatic cutting lines, guaranteeing both efficiency and quality of our aluminum circle for pressure cookers.

| Aluminium sheet plate used for bridge building |

<p>
<strong>Aluminium sheet plate</strong> is being regarded as a new star in bridge building because of its obvious advantages: bright and aesthetic appearance, high corrosion resistance, no maintenance in the entire life cycle, lower construction and maintenance cost, and high recovery rate. Almost all of the aluminum can be recycled, and more than 95% of the recycled aluminum can be obtained with the performance equivalent to the original aluminum, leaving steel far behind in this regard, which is less than 70%. with these superior performances, aluminium is considered to be the most dynamic and vital new material in bridge building.<br></p>
<p>
In 2008, a study conducted in Canada fully proved this point. Of the 9 aluminum bridges built between 1946 and 1963, there are still 6 as newly built; the density of <strong>aluminium plate</strong> products is lower, so the weight of the bridge is lower than that of the steel bridge. The low concrete bridge is conducive to manufacturing, transportation and installation. At the same time, the width of the bridge can be increased, and the supporting members can be reduced and lightened. This is particularly important for the load limitation of the bridge and the repair of historical bridges . Generally, aluminum bridge decks are 70% to 80% lighter than concrete bridge decks and most other metal bridge decks.</p>
<p>
Research shows that a steel bridge made of galvanized steel 3.24 meters wide and 28.6 meters long costs 28% to 167% higher than an aluminum bridge after 50 years. The study also shows that the cost of aluminum bridges in 33 years is lower than that of galvanized steel bridges. This is only a comparison of the cost of bridges made of two materials in the general atmospheric environment. The corrosion resistance of aluminum plate under severe corrosion conditions is higher than that of steel. At this time, the advantages of aluminum bridges will be more prominent. The advantages of aluminum in the construction of floating bridges and movable bridges are self-evident.</p>
<p>
Of course, not all aluminium alloys are suitable as materials in bridge building. <strong>3003 aluminium alloy</strong>, for example, is neither strong nor corrosion resistant enough to shoulder such a responsibility. Only stronger ones like 6061 and 7075 are sufficiently capable to fill the gap.</p>

| Differences between 5083 and 6061 aluminum sheets |
|
Posted by: BretDonogh - 08-12-2020, 03:30 AM - Forum: Knowledge & Technique

<p>
5083 aluminum sheet and 6061 aluminum sheet are different in composition, performance, application and price.</p>
<p>
<strong> Composition</strong></p>
<p>
5053 Al: residual silicon Si: 0.4 Cu: 0.1 mgmg: 4.0 -- 4.9 Zn: 0.25 Mn: 0.40 -- 0.10 Ti: 0.15 CR Cr: 0.05 -- 0.25 Fe: 0.4</p>
<p>
6061 Cu0.15-0.4-, Si0.4-0.8, Fe0.7-, Mn0.15-, Mg0.8-1.2-, Zn0.25-, Cr0.04-0.35-, Ti0.15-<br></p>
<p>
<strong> Performance</strong></p>
<p>
The comparison between 5083 aluminum plate and <strong>6061 5mm aluminium plate for sale</strong> in composition is relatively obvious. 1.6061 alloy reaches a medium strength after heat treatment (T6) which is higher than 5083 material; 2. Aluminum plate 6061-T651 is easier to process than 5083. 3.6061 alloy has excellent surface treatment and anodic oxidation characteristics, and its effect on hard oxidation is slightly better than 5083. 4.6061 also has a certain corrosion resistance that will not decrease under the exposure to the air, but it is weaker than 5083.</p>
<p>
<strong> Application</strong></p>
<p>
5083 aluminum plate has the highest strength, corrosion resistance, good fusion joint in non heat treatment alloy aluminum plate, and its hardness is obviously higher than 5052 series. <strong>5083 aircraft aluminum sheet</strong> plate is one of the representative products of super hardness aluminum plate in 5000 series. It is used in the situation where high corrosion resistance, good weldability and medium strength are required.</p>
<p>
The main alloy elements in 6061 alloy are magnesium and silicon, which have medium strength, good corrosion resistance, weldability and good oxidation effect. The internal stress of 6061 t6 aluminum plate will be relatively large, which will lead to deformation of the plate in further processing steps. The most suitable processing state should be T651, which is based on T6 for stretching to eliminate internal stress. 6061 t6 t651 aluminium sheets are widely used in all kinds of industrial structural parts with certain strength and high antimicrobial resistance.<br>
<br>
<strong>Price</strong><br>
6061 is more expensive than 5083.</p>

<p>
The density of <strong>6061 t6 aluminum plate</strong> for tooling and cake molds is 2.9g/cm3, much higher than pure aluminium grades. With two alloying metals of silicon and magnesium, 6061 aluminium plate has high strength, good corrosion resistance and good oxidation resistance. It is widely used in automatic mechanical parts, precision machining, automobile chassis, cake molds, etc., and is deeply loved by users.<br></p>
<p>
6061-T6 aluminum alloy plate has high strength, high hardness (up to HV90 degrees or more), good processing effect, and good oxidation effect. There are no trachoma pores, and the flatness is better. Conducive to improving processing efficiency and reducing material costs. T6 state is the most used 6061 aluminum alloy. It refers to the combination of solution treatment and artificial aging, and the code is CS. 6061t6 medium and heavy plate undergoes medium and heavy plate quenching, medium and heavy plate slicing, stretching machine, aging treatment, sawing, polishing, packaging and other treatments. The entire production cycle is about 10 days. After solution heat treatment, cold working is not required, and straightening and leveling can be carried out, but the mechanical properties are not affected. The 6061-T6 series is an alloy of aluminum, magnesium, and silicon. It is a heat-treated corrosion-resistant alloy. The strength and corrosion resistance are relatively good, and the uniformity is good. It is the best choice for the pursuit of low price and high quality materials.</p>
<p>
While being used in tooling and cake molds, 6061 t6 <strong>aluminum plate</strong> shows eliminated internal stress and excellent mechanical properties. After being processed by lathes, milling machines, etc., 6061 t6 alloy plates are affected by multiple forces during processing, and they have a certain degree of elasticity which does not change under the action of external force, but the external force is removed after processing, and only left internal stress that will drive the elastic recovery of the workpiece, so the size of 6061 aluminium work pieces will inevitably change.</p>
