CuW/Copper Tungsten Alloy Plate

Model Number: CTMP-P02A Brand Name: CHENTIAN Key Specifications/Special Features: Tungsten copperalloy (copper tungsten alloy, CuW, or WCu) is a pseudo-alloy of copper and tungstenAs copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other oneMicrostructure is therefore rather a metal matrix composite than a true alloyCopper tungsten alloyis a sintered copper tungsten material, and it is always manufactured by powder metallurgyForms dense composite offering hardness, wear resistance and a high softening temperature of tungsten combined with the good electrical conductivity of copper

Copper tungsten characteristics:

• Copper tungsten alloy commonly contains from 10 to 50WT% of copper, the remaining portion being substantially all tungsten
• Typical properties of the alloy depend on its composition, which is of less WT % of copper has higher density, higher hardness and higher resistivity
• Typical density of CuW90 alloy, with 10% of copper tungsten is 16.75g/cm3 and 11.85g/cm3 for CuW50 alloy
• CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 Ω.cm than CuW50
• Copper tungsten alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine
• Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper
• Sheets, rods and bars of the alloy are available as well

Copper tungsten alloy main uses:

• Copper tungsten alloy is used when a product or part needs to have a high heat resistance, low thermal expansion and high electrical or thermal conductivity
• Used to make engines and electrical devices, and it is also used in the fields of aviation and spaceflight
• Electrodes, refractory parts, heatsinks, rocket parts and electrical contacts are all made out of copper tungsten alloy
• Made into sheet metal, tubing and plate metal, which is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and switches
• Copper tungsten heat sink is used to conduct heat away from computer chips and integrated circuits, preventing thermal damage
• Depending on the electronic device, heatsinks come in different sizes and shapes
• Copper tungsten composites, with copper content (by weight) of 15 to 20 percent, are often used to make heatsinks
