Tungsten Copper EDM Electrode

Introduction

Tungsten copper EDM electrode is a kind of electrode, which are also called copper tungsten electrode, tungsten copper alloy electrode. And the tungsten copper electrode are owns the both advantages of tungsten and copper.

In view of tungsten steel, high temperature super-hard alloy die to be produced by corrosion, the common electrode wear big, slow, and the W-Cu electrical corrosion of high speed, low loss rate, precise electrode shape, excellent processing performance, to ensure the accuracy of processing pieces of greatly increased.

Properties

1, Material: 50-90% Tungsten / 50-10% Copper

2, Density: 11.80~ 16.80 g/cm3

3, Conductivity (IACS %): 54~27

4, Resistivity: 3.0~6.5 µΩcm

5, Techniques: Copper unfiltered tungsten block in vacuum high-temperature stove.

Application

Tungsten copper EDM electrodes can be used to erode any type of work piece and highly recommended when eroding tungsten carbide, nickel super alloys and other exotic materials. Copper tungsten electrodes can be machined using high speed steel cutting tools, tungsten carbide cutting tools and standard grinding wheels.

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.
