5083 belongs to Al-Mg alloy, which is widely used and especially in the construction industry. It is the most promising alloy. 5083 Aluminum Alloy has good corrosion resistance, good weldability, good cold processing and moderate [TJC STEEL]strength. The main alloy element of 5083 is magnesium, which makes this kind alloy be with good forming performance, corrosion resistance, weldability and medium strength. It is used for manufacturing aircraft fuel tank, oil pipe, as well as sheet metal parts of transportation vehicles and ships, instruments, street lamp supports and rivets, hardware products, electrical shell and so on.  

 

Introduction of 5083 Aluminum Alloy:  

5083 Al-Mg alloy, is one of the most widely used antirust aluminum, this alloy has high strength, especially with fatigue strength: high plasticity and corrosion resistance, can not be heat treatment strengthening, in the semi-cold hardening plasticity is good, cold hardening plasticity is low, good corrosion resistance, good weldability, poor machinability, polishing.  It is mainly used for low load parts which require high plasticity and good weldability in liquid or gas medium, such as fuel tank, gasoline or lubricating oil [TJC STEEL]conduit, various liquid containers and other small load parts made by deep drawing: wire is used for rivets.  

 

Applications:  

5083 aluminum alloy plate is often used in ships, ships, vehicle materials, automobile and aircraft plate welding parts, pressure vessels that need strict fire protection, refrigeration devices, TV towers, drilling equipment, [TJC STEEL]transportation equipment, missile components, armor, etc.

Technical Standards:

Representation Method:  

1) The brand of processed products  

Aluminum [TJC STEEL]Association of America (AA) on the deformation of aluminum and aluminum alloy brand expression method, namely four numbers code expression method, as early as 1957 was accepted as the United States national standard (ANSIH35.1), the main aluminum production enterprises in the United States have gradually adopted this brand expression method, later, the United States military standard (MIL),  American Society of Automotive Engineers (SAE), American Society of Materials and Testing (ASTM) have been adopted, but also in other countries.  In 1970, based on the four-digit code of AA standard, the international four-digit system of deformed aluminum and aluminum alloy was produced, referred to as IDS.  As a result, the deformed aluminum and aluminum alloy parts of AA standard have become international standards.  1) The first digit of the AA standard four-digit code indicates grouping by major alloy elements. The group is divided as follows:  

1XXX pure [TJC STEEL]aluminum (aluminum content not less than 99.00%),  

2XXX Al-Cu alloy;  

3XXX Al-Mn alloy;  

4XXX Al-Si alloy;  

5XXX Al-Mg alloy;  

6XXX Al-Mg-Si alloy;  

7XXX Al-Zn alloy;  

8XXX aluminum and other alloys;  

2) The second digit of the four-digit code, indicating the modification, or the control of impurities and combined elements,  

3) The last two digits of a four-digit code (i.e. the third and fourth digits) have the following meanings:  

For group 1XXX, the last two digits represent the two digits after the decimal point of the lowest percentage of pure[TJC STEEL] aluminum (99.00%), for example: grade 1085, ψ AL9985%.  

For groups 2XXX-8XXX, the last two digits have no specific meaning and are used only as serial numbers to identify different aluminum alloys in the same group.
