Main applications: For making rotors of aircraft wings, shileding materials for radioactive isotope (Cobalt 60),and for materials of armor piercing bullets and mould , etc
WCu alloys are used where the combination of high heat resistance, high electrical and/or thermal conductivity, and low thermal expansion are needed. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks. As contact material the alloy is resistant to erosion by electric arc. WCu alloys are also used in electrodes for electrical discharge machining and electrochemical machining.
The CuW75 alloy, with 75% of tungsten, is widely used in chip carriers, substrates, flanges and frames for power semiconductor devices. The high thermal conductivity of copper together with the low thermal expansion of tungsten allows thermal expansion matching to silicorn, gallium arsenide, and some ceramics. Other materials for this applications are CuMo alloy, AlSiC, and Dymalloy.
Alloy with 70-90% of tungsten is used in liners of some specialty shaped charges. The penetration is enhanced by factor 1.3 against copper for homogeneous steel target, as both the density and the break-up time are increased. Tungsten powder based shaped charge liners are especially suitable for oil well completion. Other ductile metals can be used as binder in place of copper as well. Graphite can be added as lubricant to the powder.
Tungsten heavy alloyWe supplies tungsten heavy alloy in a wide range of shapes and sizes, including milled forms like plates and sheets, cubes, rods, tubes, spheres and custom fabricated forms according to specific drawings.Applications Radiation Shielding for x and γ rayWeights and CounterbalancesBoring Bars and Grinding QuillsCrankshaft BalancingRotating Inertia MembersOrdnance ComponentsHigh Temperature ToolingTechnical datasheet for tungsten heavy alloyTungsten heavy alloy | W-Ni-Fe | W-Ni-Cu | |||||
