Rolling State Tungsten Copper Alloy Preparation Materials

The present invention provides a method for preparing tungsten-copper alloy rolled state, which involves a tungsten copper alloy materials.

Characterized in that:

It can solve the poor compatibility and a density of less than 99%, the high manufacturing cost of equipment, process complexity, energy consumption, low productivity among the existing problem of tungsten-copper alloy phase to phase. Tungsten copper alloy rolled state is made of tungsten powder and copper powder.

Preparation:

1) Prepared mixed powder;

2) Produced blank;

3) The billet was subjected to vacuum degassing;

4) Made tungsten copper alloy extruded material;

5) The tungsten-copper alloy extruded material is heated, pressurized after too.

The present invention rolling state phase and phase tungsten-copper alloy material has good compatibility, density increased 0.2% to 0.5%. The preparation method is simple and low cost of the necessary equipment, simple process, high energy consumption and production efficiency. The present invention is suitable for EDM electrodes, welding electrode, electronic packaging, and the preparation of the application of heat sink materials, and other fields.
