Anodized Aluminum Square Tube - Processing Instructions
Anodized aluminum square tubes are available in a large selection of cross-sections. The anodized layer is electrically non-conductive, very hard, and can be colored upon request. The anodized layer consists of Al2O3 and is very thin and firmly bonded to the aluminum substrate. The hardness of the anodized layer is approximately 8-9 on the ten-point Mohs scale. The surface treatment, anodizing, is carried out before cutting – i.e., the cut edges are bare.
