For PCD Tools Disk Erosion tungsten copper electrode/EDM electrode/welding electrode

Tungsten copper electrode for EDM and ECM
Our tungsten copper electrode for EDM and ECM is manufactured by the press, sinter, and infiltrate process. In order to reach a consistent homogeneous material giving high and even burning rates, we use virgin and excellent powders. Tungsten copper alloys are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) as electrodes. Tungsten copper is used in plunger/sinker applications where intricate definition is required.

Application:
Copper tungsten electrodes and tungsten silver electrode are widely used for machining tungsten carbide, PCD tools and high speed steel. The electrical conductivity increases with the amount of copper and the electrode wear increases with the amount of tungsten. The majority of copper tungsten electrodes for EDM is a 70% tungsten, 30% copper mixture. (except rolled sheet which is 60% tungsten, 40% copper. ) Other mixtures are available such as 80% tungsten, 20% copper; 75% tungsten, 25% copper, etc.

Tungsten copper welding electrode
Tungsten copper (Class 10) is used for flash and butt welding electrodes in applications in which high heat resistance, higher electrical and thermal conductivity, high malleability, and low thermal expansion are required. This metal is created by combining 45% copper and 55% tungsten, resulting in a dense, hard metal with superior wear resistance and strength.
Tungsten copper (Class 11) contains 25% copper and 75% tungsten. Like Class 10, it has superior wear resistance and strength and good thermal and electrical conductivity. However, it is harder than Class 10 and used in applications that require moderate pressure. Common uses include projection welding electrodes, flash and butt welding electrodes, light upsetting and seam welding bushings, and spot welding low conductivity steels. It is also widely used in chip carriers, substrates, flanges, and frames for power semiconductor devices.
Tungsten copper (Class 12) contains 20% copper and 80% tungsten. Being stronger than Class 10 and 11 tungsten copper, it is commonly used in heavy duty projection welding electrodes, electro-forming and forging electrode facings for upsetting studs and rivets, and cross wire welding. It is also used in the liners of some specialty shaped explosive charges for the defense and oil and gas industries.
