Features
The arc resistance of the tungsten contact produced by cutting the tungsten rod or pressing the high temperature sintered tungsten sheet and iron rivet furnace by tungsten rod cutting or powder pressing reduces the current consumption. Dynamic performance hits.
Tungsten-nickel-copper: Tungsten-nickel-copper alloy is an alloy composed of tungsten as the matrix (W content is 90-95%) and added with Ni, Cu and other elements, and its density is as high as 16.8-18.8 g/cm³.
Mainly used in electric products, such as automotive relays, car horn switches, etc.
