75/25 CuW alloy Tungsten copper alloy rods for industrial
Copper tungsten alloy bar is composed of tungsten and copper, which own the excellent performances of tungsten and copper, such as good heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity.
Copper Tungsten Alloy Heat Sink
Tungsten copper alloy heat sink
Copper tungsten alloy is widely used as heat sinks concerning with radiator for car, refrigeration and air conditioning systems because of its low thermal expansion, heat-resistant, ablate-resistant, excellent thermal and electrical conductivity.
Copper tungsten alloy heat sinks galvanically plated with Ni or NiAu or electroless Ni plated Semi-finished products: up to 100x100mm with a thickness of 0.5 to 50mm. Tungsten copper heat sink with advantages of high thermal conductivity, excellent hermeticity and excellent flatness.
Copper Tungsten Electrical Contacts
Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing.
Our copper tungsten alloy materials are used owing to their unique physical properties.
Copper tungsten alloy electrical contacts have good resistance to arc erosion, mechanical wear, contact welding and good conductivity.
Copper tungsten alloy electrical contacts are widely used as contact tips and contact electrode.
