Surface treatment of aluminum screw fastenal, chrome

When the aluminum screw is not surface treated, its color is silver. It is still beautiful without surface treatment, but sometimes it is necessary to change the performance of the aluminum screw or change the color according to the product requirements, then the surface of the aluminum screw is needed. The treatment is carried out to change the surface color of the aluminum screw fastenal, or to make the performance of the aluminum screw superior.

Aluminum alloy screws can be chrome-plated or anodized. aluminum screw fastenal chrome plating can improve wear resistance. For example, aluminum engine cylinders are chrome-plated. The chrome plating has no flatness, the substrate has a high finish, and the plating finish is high. If anodized, the finish can be improved by chemical polishing/electropolishing, and then anodized. The cost of chrome plating is higher than that of anodizing.
If you want to make your aluminum screw performance even better, you can surface your aluminum screws.
