5083 alloy is not widely used in the manufacture of aerospace vehicles. European Airbus uses a certain amount of this alloy in the manufacture of aerospace vehicles. In addition, some foreign companies use 5083 alloy to manufacture cruise missiles. The 5083 forged aluminium parts are used in railway vehicles, special automobiles, tanks, petrochemical containers, ship inspection, power electronics industry, etc.
 
 
The thermoplasticity of 5083 aluminium alloy forgings is low, and the processing rate of several passes is not too high at the beginning, which is controlled at 3%-5%. In the middle stage of forging, the hot-working structure increases, but the core of ingot is still as-cast structure and there is no plastic deformation. At this time, the processing rate should be increased so that the forgings can cross the fragile zone as soon as possible and the processing rate should be controlled at 5%-15%. In the later stage of forging, in order to compensate for the heat loss of forging, the same is true. In order to ensure the final structure and properties of hot rolled products, 15%-35% pass processing rate can be adopted.
