Tungsten copper EDM trapezoidal electrode

Our create shape electrode is made by tungsten copper alloy. the unique design( shape and copper tungsten proportions), this edge allows the operator create inside radius on the finished tool that previously could only be eroded using a wire machine. Our CuW alloy have high physical and mechanical properties, as well as high thermal and electrical conductivity, these properities make our materials very sutitable for the die inserts and electode facing.Our Copper tungsten alloy are designated as ASTMB702, RWMA Class 10, RWMA Class 11, RWMA Class 12, GB/T8320-2003Typical properties:MaterialCompositionDensityElectrical ConductivityHardnessRWMA(%by weight)(g/cm³)(% IACS)(Rockwell )ClassCuW5555W:45Cu12.34976 HRB10CuW6060W:40Cu12.754782HRBCuW6565W:35Cu13.34488HRBCuW7070W:30Cu13.84294HRB11CuW7575W:25Cu14.53898HRB12CuW8080W:20Cu15.1534109HRB
