Description
Silver-Copper Alloy is widely used for welding various precise instrument.And also used in the contact wire of electrization railway,the contact of the air circuit breakers,voltage controller,telephone relays,contactors,starters devices, conductive ring and the fixed contacts,vacuum brazing , but also to manufacture coins, decorations and tableware.
