Factory Direct W75Cu25 Tungsten Copper Flat Bar High Hardness Copper Tungsten Plate Strip

Our W75Cu25 Tungsten Copper Flat Bar (CuW75) is a pseudo-alloy composed of 75% Tungsten and 25% Copper. Manufactured via the vacuum infiltration method, our copper tungsten strips combine the high hardness, high melting point, and anti-adherence of tungsten with the outstanding electrical and thermal conductivity of copper. It is widely used in EDM sparking electrodes, resistance welding, electronic packaging, and heat sink applications. Email this page Submit your Inquiry
