 Introduction of a 5083 aluminum 
 5083 belongs to the Al-Mg-Si alloy, using a wide range, especially the construction industry is inseparable from this alloy is the most promising alloys. Good corrosion resistance, good weldability and cold better, and has a moderate intensity. 5083 the main alloying elements of magnesium, has good forming properties, corrosion resistance, weldability, moderate intensity, for the manufacture of aircraft fuel tanks, sheet metal pieces of tubing, as well as transport vehicles, ships, meters, street lighting bracket and rivets. metal products, electrical appliances such as Shell. 
 AL-Mn alloy is the most widely used as a rust-proof aluminum, the strength of this alloy, especially with anti-fatigue strength: plasticity and corrosion resistance, high heat treatment can not be strengthened, in the semi-cold hardening plasticity good low plasticity when cold hardening, good corrosion resistance, good weldability, can be cutting performance bad, can be polished. The purpose for the requirements of high plasticity and good weldability, low-load part of the work in the liquid or gaseous medium, such as mailboxes, gasoline or lubricating oil conduit, a variety of liquid containers and other deep drawing production load parts: wire used to do the rivet 
 Second, the 5083 aluminum range of applications 
 5083 aluminum is commonly used in ships, vessels, vehicles, welding materials, automobile and aircraft plates, stringent fire, pressure vessels, refrigeration devices, television tower, drilling equipment, transportation equipment, missile components, and armor.

 Five, the relevant technical standards 
 Aluminum with a national standard (GB / T 3880-2006), uniform standards applicable to the aluminum alloy strip materials. 
 Six, the 5083 aluminum 
 1) The grades of processed products 
 U.S. Aluminum Association (AA) on the deformation of aluminum and aluminum alloy grades, both the four-digit code, as early as in 1957 was accepted as American National Standards (ANSIH35.1), primary aluminum production enterprises in the United States gradually have This grade is expressed, the U.S. military standard (MIL), Society of Automotive Engineers (SAE), the United States Society for Testing Materials (ASTM) and so have been using, but also extended to other countries. 1970 again the AA standard set of four-digit code based on the international four-digit system to produce a deformation of aluminum and aluminum alloy grades, referred to as the IDS. Thus, the deformation of aluminum and aluminum alloy part of the AA standard also become an international standard. 1) AA standard four-digit code the first digit represents the major alloying elements into groups, the groupings are as follows: 
 The 1XXX pure aluminum (aluminum content not less than 99.00%), 
 2XXX alloy AL-CU; 
 3XXX alloy AL-MN; 
 4XXX AL-SI alloys; 
 5XXX AL-MG alloy; 
 6xxx AL-MG-SI alloys; 
 7XXX AL-ZN alloy; 
 8XXX aluminum and other elements of the alloy; 
 2 of 2) four-digit code number that represents the modified or the control of impurities and the combination of elements, 
 3) four-digit code the last two digits (both three and four digits), its meaning is as follows: 
 The 1XXX group, the last two digits after the decimal point of pure aluminum the lowest percentage (99.00%), two digits, such as: grade 1085, said ΨAL9985. 
 2XXX-8XXX group, preferably a two-digit no specific meaning only as a sequence number to identify the different aluminum alloys in the same group.
