Silver plating in accordance with QQ-S-365, ASTM B700
Our silver plating process is applied electrolytically. Silver has a very high electrical conductivity, excellent heat conductivity and a low contact resistance compared to other metals except for gold. This makes silver plating ideal for the communication applications, microwave application, electronics, medical and aerospace industry. It is often chosen as a less expensive alternative to gold for electrical connections. Below are the various specifications that EMIRFI Shield Plating Inc. provides for your various applications.
