TanSpark® 80/20

is a high end copper tungsten material manufactured from a very pure and fine grain tungsten powder.
The material has high density and is completely free from porosity and other impurities.


provides higher metal removal rate and lower edge wear than most other tungsten copper composite materials.
The uniform and small grain size of the tungsten powder used in combination with the final micro hardness makes our TANSPARK 80/20 the ideal material for true precision machining. A superior surface finish and excellent machinability is to be expected from this premium material.

A very low wear is also guaranteed if used in combination with Oelheld Ionoplus IME-ET or IME-ZK.

This is the obvious choice of material when eroding/edming expensive tungsten carbide and PCD when the requirment on the final result is very high.

TanSpark® tungsten copper – Highest quailty without any compromise!
