High Precision Ultra Flat Aluminum Plate


High Precision Ultra Flat Aluminum Plate

High Precision Flat Aluminum Plate Features
Surface is polished by sand belt of 400 mesh,so anodized oxidation can be done directy without milling.Excellent quenching process leads to small deformation,which is better than T651,and less internal stress.The best thickness tolerance is 0.0,+0.05mm,the same quality as plates from Germany,Japan & Taiwan.

O
(1) It is intermediate strength alloy,and it is also the most representative one.it has good corrosion resistance,weldability,and formability.although it is intermediate strength alloy,it has good anti-fatigue strength,and excellent seawater corrosion resistance.
(2) It has good corrosion resistance.it is practical nonheat treated alloy,but its strength is the best among the practical.nonheat treated alloy,it is suitable for welding structure,it has excellent seawater corrosion resistance and low temperature resistance.
(1) Heat Sink
(2) Radiator
(3) Liquid crystal semiconductor manufacturing devices injection molding mold rall transit,tank storage.
