PURE PRECIOUS METALS
Pure precious metals like silver, copper, nickel, tungsten, palladium originate from ores extracted from deposits around the world. After successive stages of extraction, metallurgical reduction, refining, and purification, they are processed into various forms to meet industrial requirements: bars, metal strips, rivets, pads or machining parts.
Thanks to their high electrical conductivity (up to 105% IACS for pure silver), they represent a preferred solution for applications requiring high performance, reliability, and stability. They are mainly used in relays, small switches and devices operating at low current levels, typically ranging from 1A to 100A.
