Hard Gold Plating
Hard gold plating contains a small amount of hardener.
Our hard gold plating has a cobalt content of 1 to 3 wt% in order to increase the hardness compared to bright gold plating, and has a high hardness of Hv190 to 250.
Therefore, contact resistance of the hard gold plating deposit is higher than that of pure gold plating or bright gold plating.
Even with high-hardness, the hard gold plating of Mitsuya is superior in wear resistance, electric conductivity, soldering characteristics and low contact resistance.
Hard gold plating is required particularly in the following components:
・The sliding parts that require conductivity and hardness.
・The slip ring that require conductivity and sliding property.
Contact resistance of Bright gold and Hard gold are almost the same
Functional property
- Abrasion & Wear Resistance
- Low Contact Resistance
