Precision cast aluminum plate have a precision machined surface for superior flatness, flat within . 015'', and +/- . 005'' thickness tolerance, and are protected with PVC plastic on both sides. precision cast aluminum plate typically has a surface finish of 25 RMS or better.
 
 applications include, but are not limited to, Computer & Electronics, Pharmaceuticals, Machining fixtures, Drill jigs, Index tables, Semi-Conductor, Automotive Molds
 
Characteristics of precision cast aluminum 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.
