Hard Gold Plating

sample of Hard Gold Plating

Our Hard Gold Plating is engineered for superior durability, achieving a high hardness range of HV190 to HV250, significantly surpassing conventional bright gold. This hardness is achieved by adding a small amount of hardener, specifically Cobalt (1-3%wt), to the deposit.

While the Cobalt additive slightly increases the contact resistance compared to pure or bright gold, our hard gold plating maintains an excellent overall performance profile:
・Superior Wear Resistance
・High Electrical Conductivity
・Excellent Soldering Characteristics
・Low Contact Resistance

Hard Gold Plating is the preferred choice for components that experience constant movement or friction and required a combination of hardness and conductivity.

Contact resistance of Bright gold and Hard gold are almost the same
