I. Introduction of 5083 aluminum plate
5083 belongs to Al-Mg-Si series aluminum alloy, which is widely used. Especially in the construction industry, it is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability and medium strength. The main alloying element of 5083 is magnesium, which has good forming and processing properties, corrosion resistance, weldability and medium strength. It is used in the manufacture of aircraft fuel tanks, oil pipes, and sheet metal parts for transportation vehicles and ships, instruments, street lamp brackets and rivets. Hardware, electrical enclosures, etc.
AL-Mn aluminum alloy is the most widely used rust-proof aluminum. This alloy has high strength, especially fatigue resistance: high plasticity and corrosion resistance, no heat treatment strengthening, and semi-cold hardening. Good plasticity, low plasticity during cold work hardening, good corrosion resistance, good weldability, poor machinability and polishing. AL-Mn aluminum alloys are mainly used for high-load plasticity and good weldability. Low-load parts working in liquid or gaseous media, such as mailboxes, gasoline or lubricating oil pipes, various liquid containers and other deep drawing Small load parts made: wire used to make rivets
2, the application range of 5083 aluminum plate
5083 aluminum plates are commonly used in ships, ships, vehicle materials, automotive and aircraft welded parts, pressure vessels requiring strict fire protection, refrigeration equipment, television towers, drilling equipment, transportation equipment, missile components, armor, etc.

6, 5083 aluminum plate representation
1) Grades of processed products
The Alcoa Association (AA) has a four-digit code representation for the deformation of aluminum and aluminum alloys. It was accepted as a US national standard (ANSIH35.1) as early as 1957, and the major aluminum producers in the United States gradually Using this type of branding method, the US Military Standards (MIL), the American Society of Automotive Engineers (SAE), and the American Society for Testing and Materials (ASTM) have been adopted in succession and are being extended to other countries. In 1970, based on the four-digit code of the AA standard, the international four-digit system grade of deformed aluminum and aluminum alloy was produced, which is referred to as IDS. As a result, the deformed aluminum and aluminum alloy parts of the AA standard have also become international standards. 1) The first digit of the AA standard four-digit code indicates that it is grouped by major alloying elements. The grouping is as follows:
1XXX pure 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 alloy of aluminum and other elements;
2) The second digit of the four-digit code indicates the modification, or the control of impurities and combined elements.
3) The last two digits of the four-digit code (both the third and fourth digits) have the following meanings:
For the 1XXX group, the last two digits indicate the two digits after the decimal point of the lowest percentage of pure aluminum (99.00%), for example: grade 1085, which means ΨAL9985%.
For the 2XXX-8XXX group, the last two digits have no specific meaning and are only used as sequence numbers to identify different aluminum alloys in the same group.
