Tungsten copper alloy bar is widely used in boat building, war industry, car industry and communication industry where the components need good wear proof and great corrosion resistance, anti-deformation and deflection. It is used for making drills, end mills, reamers cutting punching and measuring tools. And it is also used in self-lubricate axletree field. Because of the high electrical conductivity and low consumption, tungsten copper alloy bars are widely used to make grid siderod, lead, support, tungsten electrode for the gas discharge lamp.
Application as resistance welding electrode
Tungsten copper alloy bar is integrates the advantages of tungsten and copper, such as temperature resistance, good resistance to arc erosion, high density, high melting point, excellent hardness, superior wearing resistance, high ultimate tensile strength, high electric and heat conductivity. What's more, it is easy to be cut in machine. Especially for its transpiration cooling advantage, tungsten copper alloy bar is available as good wear proof and great corrosion resistance materials, such as projection welding electrode and butt welding electrode.
Application as spark electrodes
High temperature resistant and super hard alloy mould is made of tungsten steel, but when it comes to galvanic corrosion, general electrode runs slow and has much consumption. While tungsten copper alloy bar's advantages of good resistance to arc erosion, low loss rate, precise shape of electrode, excellent processability can ensure the precision of the Mechanical machining parts.
Application as high-pressure discharge tube electrode
When high voltage vacuum tube begins to work, it raises the temperature of the contactor material up to several thousand degrees within a time of several tenths of a second. Thermal shock resistance, high toughness, electrical and thermal conductivity of the tungsten copper alloy bar provides discharge tube with necessary conditions of stable work
Application as electronic packaging materials
Tungsten copper alloy bar integrates the advantages of tungsten and copper, not only has tungsten advantages of low expansion features but also possesses copper superiority of high thermal conductivity. What is more, thermal expansion coefficient and thermal/heat conductivity of the tungsten copper alloy bar could be balanced by adjusting the composition of the material. All of those are convenient for the use of electronic packaging materials.
