Differences between 5052 and 5083 aluminum plate

Both the 5052 aluminum plate and the 5083 aluminum plate belong to the 5-series aluminum-magnesium alloy, but their magnesium contents are different, and other chemical components are also slightly different.
　　Their chemical compositions are as follows:
　　5052 Si 0+ Fe0.45 Cu0.1 Mn0.1 Mg2.2-2.8 Cr0.15-0.35 Zn 0.1
　　5083 Si 0.4 Fe0.4 Cu0.1 Mn0.3-1.0 Mg4.0-4.9 Cr 0.05-0.25 Zn 0.25

　　The differences in chemical compositions of the two result in their varied developments in mechanical performances. 5083 aluminum plate 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.
　　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 marine grade aluminum plate. 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.

Slitting of 1mm 2mm 4mm aluminium strip

图片
What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

Diamond Embossed Aluminum Sheet Application

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
