Tungsten Copper Alloy Round Bar W Cu Alloy Bars W80 W75 W70 For Airplane Industry
Tungsten copper alloy combines the properties of both tungsten and copper metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to be machined.
Main Sizes of Tungsten Copper Alloy Round Bars:
Diameter: 1 - 100 mm
Length: 50 - 500mm
Diameter Tolerances: +/-0.05mm - 0.1mm
Length Tolerances: +/- 0.1mm, +/-0.5mm
Advantages of WCu Alloy Round Bars:
High arc resistance
High thermostability
High strength
Lighter weight than pure tungsten
Good electrical conductivity
