Frequently Asked Questions

A coating of aluminum oxide is grown from the aluminum by passing an electrical current through an acid electrolyte bath. The coating thickness and surface characteristics are tightly controlled to meet end product specifications.

The purpose of anodizing is to form a layer of aluminum oxide that will protect the aluminum beneath it. The aluminum oxide layer has much higher corrosion and abrasion resistance than aluminum. There are some types of anodizing that produce a porous oxide layer that can be colored with organic dyes or metallic pigments giving the aluminum a decorative and protective finish.

Hardcoat anodizing has a greater hardness and thicker oxide layer that makes it well-suited for applications that require excellent engineering characteristics. Hardcoat anodizing has a thickness of 1-3 mills.

Softcoat anodizing is a thin, highly porous, clear coating that will easily receive colorant dyes. Softcoat anodizing also has a thickness of 0.3-0.8 mils thick.
