Your Metal Finishing Solution

Gold Plating

Advanced Surface Technologies offers Type III pure Gold and Type I and II Nickel hardened Gold on a wide variety of substrates including Aluminum, Brass, Copper, Steel, Stainless Steel and Magnesium. Our functional Gold coatings conform to MIL-G-45204, ASTM B488 and AMS 2422. With gold’s resistance to oxidization, good electrical conductivity, solderability and reflective properties it’s an extremely dependable material used in aerospace, electronics and medical applications. As the gold plating process requires a controlled environment, we perform operations in an area with independent air systems, separated from other plating processes.
