TanSpark® 80/20 – The Ultimate Tungsten-Copper composite for precision EDM
TanSpark® 80/20 is a premium tungsten-copper (WCu) material manufactured from ultra-pure, fine-grain tungsten powder and copper infiltration. With its high density, porosity-free structure, and freedom from impurities, it is engineered for the most demanding EDM applications .
Superior performance and durability
Higher material removal rates (MRR) compared to conventional WCu composites.
Lower edge wear thanks to uniform grain size and high final micro-hardness.
Outstanding surface finish and machinability – ideal for micro-EDM and complex electrode geometries.
Optimized for minimal electrode wear
When paired with advanced dielectric fluids such as Oelheld Ionoplus IME-ET or IME-82 , TanSpark® 80/20 ensures minimal edge wear. This makes it the go-to choice for EDM of tungsten carbide, PCD, and other high-value materials , where precision and consistency are critical.
Summary – TanSpark® tungsten copper
TanSpark® 80/20 combines strength, precision, and efficiency . For manufacturers requiring long electrode life, superior accuracy, and reliable process stability, it is the clear choice.
TanSpark® – quality without compromise.
