Metal Cutting offers specialty refractory metal electrodes. Our electrode materials expertise is in tungsten, molybdenum and their alloys, including copper tungsten and silver tungsten as well as carbide compositions and heavy metal electrodes. Our electrodes are used in high speed large volume automated resistance spot welding manufacturing environments and are also excellent for die sinker EDM.
Copper Tungsten is by far our most popular electrode material for both applications. Die Sinker EDM requires various compositions and we offer all the standard ratios in small to large sizes with uniform blending throughout the block and superior density to eliminate porosity. Our powder metallurgy expertise produces materials that are easily machined to your final shape.
We even have a new proprietary composition that has been specifically formulated for exceptional speed and wear performance for the electrical discharge machining of carbides. This exclusive new material grade is C-EDM and it outperforms even our own standard Copper Tungsten electrodes. C-EDM has been shown to have a 52% longer life and cuts at 25% faster speeds, resulting in significant manufacturing advantages.
Copper Tungsten Electrodes
A best-selling product for resistance spot welding and die sinker EDM applications, Metal Cutting’s copper tungsten electrodes resist cracking and offer superior performance. Our unique non-defective bonding (NDB) technology creates a copper tungsten electrode that provides the desired levels of thermal conductivity while reducing wear and increasing electrode life. The result is optimal productivity and weld quality for your electrode applications.
Silver Tungsten Electrodes
Our high-performance electrodes for high-speed, automated welding applications include silver tungsten electrodes made from a complex alloy that exhibits the desired levels of thermal and electrical conductivity and moderate hardness at high temperature.
