Silver plating is an electro-chemical process which puts a thin layer of silver over another metal. It is principly used for lubricity, conductivity and decoration. It is used on products like gears and seals for lubricity, buss bars and contacts for conductivity and pieces of art for decoration. We are very successful in plating silver for each of these purposes. A typical thickness for silver plating is 0.0001" to 0.0005".
When silver is applied for lubricity and conductivity, it is typically plated directly on the base metal, unless an undercoating is required for adhesion such as a nickel stike to help the plating adhere to nickel alloys. For decorative applications the silver may have an undercoating of bright nickel to take advantage of the nickel's ability to shine.
Frequently Asked Questions
Why is silver used for electrical connections even though it tarmishes so fast? Tarnished silver or silver oxide is almost as conductive as silver and it is still more conductive than gold.
