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.
