W80Cu20, Tungsten Copper Electrodes (Copper Tungsten Alloy, CuW, or WCu) is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, 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.
The electrical and thermal properties of the alloy vary with different proportions. Copper increases the thermal conductivity, which plays a huge part when being used in circuit breakers.
Electrical resistivity with an increase in the percentage of tungsten present in the alloy, ranging from 3.16 at 55% tungsten to 6.1 when the alloy contains 90% tungsten.
An increase in tungsten leads to an increase in ultimate tensile strength up until the alloy reaches 80% tungsten and 20% copper with an ultimate tensile strength of 663 MPa.
After this mixture of copper and tungsten, the ultimate tensile strength then begins to decrease fairly rapidly.
W80Cu20 Tungsten Copper Electrodes is used in a product or part requires high heat resistance, low thermal expansion and high electrical or thermal conductivity. Tungsten copper is used to fabricate engines and electrical devices. It is also used in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts are all made by copper tungsten alloy. The alloy is also made into sheet metal, tubing and plate metal. Copper tungsten alloy is used to make contacts for both high and medium voltage electrical devices, and for high speed steel devices and switches.
