Resistance Welding Electrodes for Industrial

Wholesale W75 copper tungsten electrodes for resistance welding

Consisting of pure tungsten (W) powder suspended in a matrix of copper (Cu), these alloys are known for good thermal and electrical conductivity, low thermal expansion, and resistance to erosion from arcing.  Thus, they are often used as electrical contacts, particularly in high voltage applications. Most sizes and shapes can be supplied with short lead times. We can also manufacture parts from these materials to your specifications.

Advantages:

*  High arc resistance combined with good electrical conductivity
*  High thermal conductivity
*  Low thermal expansion

Applications:

*  Arc contacts and vacuum contacts in high/medium voltage breakers or vacuum interruptors
*  Electrodes in electric spark erosion (EDM) cutting machines
*  Heat sinks for passive cooling of electronic devices
*  Electrodes for resistance welding

Tungsten copper electrodes is used to satisfy the demand of combination of electrical conductivity resistance to arccorrosion. Tungsten Copper Electrode are use as High electrical and High thermal conductivity in for various welding Process. For racking contacts.electric discharge machine and but welding etc.

In the resistance welding process, the parts to be joined are pressed together and heated by an electric current until pools of molten material form at individual points between them. This operation requires high currents and large pressing forces.

Welding electrodes made from our refractory metals and their alloys have a relatively high level of electrical conductivity while also exhibiting outstanding stability at high temperatures. They therefore have a considerably longer service life than conventional materials such as copper and copper alloys.

Our welding electrodes made of tungsten, molybdenum and their alloys are particularly suitable for welding highly conductive materials such as copper. They are used in the following processes: Spot welding, Roller welding, Projection welding, Upset welding.

We supply 100% infiltrated tungsten-copper comprising 75% tungsten and 25% copper for your projection welding process according to RWMA standard. This composite brings together the best of both materials: The strength of tungsten and the excellent thermal and electric conductivity of copper.
