W75Cu25 Tungsten Copper Welding Rods For High Arc ResistanceTungsten Copper Welding Rods are a composite of tungsten and
copper, which has excellent properties of tungsten and copper, such
as heat resistance, ablation resistance, high strength, excellent
thermal conductivity and conductivity. Tungsten copper alloys are
easy to machine. Tungsten copper alloys are widely used in engine,
power, electronics, metallurgy, aerospace and aviation industries.
Using CIP molding, sintered tungsten skeleton and copper (silver)
infiltration technology, tungsten copper composite products with
large size and special shape containing 6-90% copper, such as
electrical contacts, electrodes, refractory parts, radiators and
rocket components, are produced.
