Product Description

Electrodes for Tungsten Copper Alloy High Voltage Discharge Tubes


1. Tungsten Copper Alloy High Voltage Discharge Tube Electrodes Specifications:


The temperature of the contact material will rise by several thousand degrees Celsius in a split second while the tungsten copper alloy high-voltage vacuum discharge tube is operating. The tungsten copper's strong ablation resistance, high toughness, and good electrical and thermal conductivity offer the parameters required for the discharge tube to operate steadily.


Electrical materials made of tungsten copper alloys are primarily separated into electrical contact materials and electrical processing materials.

(1) Electrical contact material. The most significant category of electrical materials is this one. They have high resistance to arc ablation and fusion welding, and are used as electrical contacts, electrical contacts and electrodes in various high and low voltage switching appliances and certain instruments. Electrical contacts are the most widely used type of tungsten-copper materials, especially tungsten-copper materials with a copper content of 20% to 40%. They are mainly used in medium and high voltage and medium and large current switching appliances. Such as the protection circuit breaker contacts and other contacts and contacts of the power transmission network. Tungsten copper contacts containing 15% to 20% Cu can be used on circuit breakers with voltages up to 500,000 V or higher.

(2) Electrically processed materials. Refers to electrode and mold materials used in resistance welding, electric riveting, electric upsetting, and electric discharge machining. EDM requires electrode or mold material to have good electrical conductivity and arc ablation resistance to ensure machining accuracy, so tungsten copper materials are mostly used. Resistance welding also uses tungsten copper materials. Electric riveting and electric upsetting also use tungsten copper material in some occasions.


2.Size of High Voltage Discharge Tube Electrodes Made of Tungsten Copper Alloy:


1). Composition: tungsten copper alloy (WCu);
2). Type: round rod and square rod;
3). Outer diameter: 3.0mm~380mm;
4). Length: up to 1000mm;
5). Wall thickness: minimum 0.3mm.

We can customize/cut into required shapes and specifications according to the different needs of customers.
Copper-tungsten discharge tubes provide stable machining performance in carbides and other refractory metals. It is widely used for machining tungsten carbide, thin sheets, small diameter rods and pipes when a fine surface finish is required.
