SILVER-GRAPHITE FIBRE TYPE MATERIALS USED FOR MAKING CONTACTS

The present work studies a new type of silver-graphite fibre materials used for making contacts and their new process e.g.extruding, silcing,decarburizing,etc. The physical properties and electrical life of the contacts can be greatly improved. The materials have a good welding resistance,hence they are the ideal contact materials for automatic switches which require reliable welding resistance as well as long electrical life.
