Tungsten - Copper / Plate
Description
Tungsten-Copper (W-Cu) alloy is a material composed of tungsten and copper. It has an extremely high melting point which depends on the ratio of the two metals used in the alloy but typically ranges between 1400 and 1800℃, making it suitable for many applications that require materials with a high degree of heat resistance. In addition, tungsten copper alloy’s mechanical properties make it an excellent choice for use in components with high wear resistance.
Alfa Chemistry specializes in providing high tungsten-copper plates on the market today. We can also customize various shapes of tungsten-copper alloy products according to your requirements or drawings.
