Tungsten copper W90 block is composed of 90% W and 10% Cu, its density is up to 16.75g/cm3, hardness reaches more than HB260, the bending strength is 1160MPa, the conductivity is 27%IACS and the softening temperature is more than 900℃.
Owing to W takes up the most of parts, tungsten copper W90 block is hard, but its toughness and ductility is not so good so that it is not suitable for bending and drawing with large angle.
Since 1990s, tungsten copper has been used as new material for electronic packaging and heat sink. At present, we can see tungsten copper everywhere, such as CPU of computer, large scale intergrated circuit, high-power microwave devices and some radiators.
| The standard length and width of tungsten copper block we are able to provide is less than 300mm, and the thickness is more than 0.1mm (±0.05mm), customized sizes and tolerances are also accepted.
