Tungsten Copper Disk

tungsten copper disk

Introduction

Tungsten copper disk is pseudo-alloy between tungsten and copper. It has the thermal stability of tungsten and good electrical conductivity of copper. Because different of melting point between tungsten and copper, we can use traditional casting process to manufacture the tungsten copper alloy.

Application

Tungsten copper disk is used widely in EDM electrodes, resistance welding electrodes, high temperature resistance parts and other industrial fields. Tungsten copper disk has high physical and mechanical properties, which can answer the need of PCD rotary tools disk erosion machining. We pay a lot of effort to research and develop and optimize our process, so that we develop quantity of products for such application.

Manufacturing Process

Tungsten copper disk machining process is powder mixed - pressing - sintering - infiltration routing. Tungsten and copper mixed powder after pressing, sintering at 1300-1500 ° phase. Preparation of this legal material is uniformly bad, there are more closed the gap, the density is usually less than 98%, but by adding a small amount of nickel activated sintering, mechanical alloying or oxide reduction method for ultra-fine, nano-powder can improve the sintering activity, thereby increasing tungsten, copper, molybdenum density copper alloy.
