Low Contact Resistance platings

Low contact resistance plating is applied to areas where metals need to be joined together. The presence of oxidation or sulfuration on metal surfaces can increase contact resistance, necessitating the use of highly corrosion-resistant plating to prevent such issues. Additionally, continuous micro sliding, often caused by external vibrations, can lead to abrasion and oxidation on the contact surface over time, resulting in increased contact resistance—a phenomenon known as fretting corrosion. Therefore, low contact resistance plating must exhibit corrosion resistance, abrasion and wear resistance, as well as good insertion and extraction performance.

Bright gold plating (with cobalt content) is a popular choice due to its low contact resistance and hardness. However, apart from gold plating, we also offer rhodium plating, bright silver plating, hard silver plating, and hard gold plating as effective low contact resistance plating options. These alternatives provide similar benefits, ensuring optimal performance and longevity in applications requiring low contact resistance properties.
