Tungsten copper bar is a combination of tungsten and copper. The manufacturing process is as follows: press the refractory metal, sinter the pressed compact at a high temperature, and infiltrate it with copper. All this is done under very closely controlled conditions. The result is a relatively hard material with superior arc and wear resistance, high physical Properties: at elevated temperatures, and good electrical and thermal conductivity.
After being discovered, tungsten sheet became a new type of lead-free shielding piece, which is commonly used for radiation protection in hospital X-ray rooms, CT rooms and other radiology departments, and has a good shielding effect on X-rays as well as γ-rays.
Copper tungsten alloy integrates the advantages of tungsten and copper, within which tungsten's melting point is higher( about 3410 ℃) and density is larger (about 19.34g/cm3). Copper has good electro conductivity, so tungsten copper alloy (ingredients range from Wcu7-Wcu50) whose micro-structure is even and it is high temperature resistance, high intensity, and large intensity. As tungsten copper has appropriate electro conductivity and heat-conductivity, so it is widely used in high temperature-resistance material, electrician alloy used in high voltage switch, electronic processing electrode, and micro-electronic material.
