W75Cu25 Tungsten Copper alloy welding electrodes

Product Description

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.
