5083 aluminum aluminium tooling plate is a machined product, with flat surfaces and a surface finish equal to 32 micro-inches or better on both sides (top and bottom). It is readily machined with very little distortion. Using proper aluminum machining methods, tolerances in the thousandths can be maintained.
 

 
Characteristics of 5083 aluminum aluminium tooling 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.
