electroplating on aluminum alloy

electroplating on aluminum alloy
The widespread use of aluminum alloys has led to the development of various electroplating and electroless plating techniques compatible with these materials. In addition to aerospace, aluminum alloy plating also meets the needs of companies in industries such as telecommunications, energy, medical and defense. Various metals can be electroplated onto aluminum alloys, including nickel, tin, and precious metals such as silver and gold.

A common problem when working with aluminum and aluminum alloys is their tendency to form oxides which prevent proper adhesion of coatings. Using a galvanized film as a primer before nickel plating the workpiece can often alleviate this problem.
