Silver Plating Glossary
Silver in its purest form is a soft, white, lustrous metal which is extremely malleable and ductile and capable of taking a high polish. It may be electrodeposited in either a soft dull finish or a hard semi-bright finish, suitable for use in the aerospace industry and the electronic and electrical industries. The two types of finishes available are:
Semi-Bright Silver
Semi-bright silver posseses certain qualities which make it particularly suitable for use in many aerospace applications. It will resist the effects of fretting between two different metal components when they come into contact with one another, it has extremely good wear resistance, making it suitable for the finishing of bearings, and it is extremely easy to solder given its ultra-fine grain structure.
Dull Silver
This coating is more versatile than semi-bright silver because it can be applied to components from varying industrial sectors. This silver is good for use on electrical contacts and relays as it is silver in its purest form (99.9%) and therefore a very efficient electrical conductor. The finish is also very lubricious which makes it suitable for use in aerospace components where resistance against rubbing wear are essential.
Silver plating can be applied to various base metals, some of the most common types are copper, brass and even aluminium.
Silver can be plated to various specified thicknesses depending on each customers requirements, or to the relevant BS or Aerospace spec.g/m².
