5083 High Precision Aluminum Cast Plate

Aoyin 5083 high precision aluminum cast plate has finer and homogeneous grain structure, with special state of stress digestion. Which makes almost no deformation after high speed of machining and cutting. Aluminum rolled plate sheet has orientated structure with strip distribution of grain along the processing direction, which makes more or less deformation of the parts after machining.

Characteristics of  5083 high precision aluminum cast plate

1.    Homogenised and stress relieved

2.    Precision milled, roughness Ra0.4um, foiled on both sides

3.    High strength, good corrosion resistance and oxidation resistance.

4.    Isotropic homogeneity, higher dimension stability.

5.    Anti-magnetic, anti-radiation.

6.    Fine surface milling as requirement. Good surface quality, the finished product can be double side filmed.
