Unrivaled Conductivity and Corrosion Protection

Metal Finishing Group provides Gold Plating services, applying a thin, high-performance layer of gold to various substrates. Gold plating is a premier choice in metal finishing, valued for its exceptional electrical conductivity, superior corrosion resistance, excellent solderability, and aesthetic appeal.

Gold plating is chosen when components require the highest levels of electrical performance, absolute reliability in corrosive environments, or a luxurious, non-tarnishing finish. It is ideal for critical applications across electronics, aerospace, and medical industries where compromise on quality is not an option. This precious metal coating ensures long-term functionality and contact integrity.
