Anodising is a process for producing decorative and protective films on articles made from alumnium and its alloys. It is essentially a process where a thick film of aluminium oxide is built up on the surface of the aluminium through the use of a direct current electrical supply. After anodising the surface may be coloured with a dye or by an electrolytic method using appropriate metal cations, and then sealed by placing in boiling water, the pores in the oxide layer being closed off.
Anodize finish allows aluminium extrusion to be more corrosive resistant compared to Mill Finish. Our anodizing product thickness range from 5-25 micron, with available choices, such as: natural anodizing, color anodizing (bronze, black, silver satin and gold).
