As erosion electrodes, it is useful to choose copper electrodes with high electrical conductivity and hardness.
Electrolytic copper should not be preferred. Because, Due to not contain any alloying elements, its mechanical properties are extremely low and difficult to machining.
The hardness of a copper alloy such as our product CuproMax (zirconium copper) is high and its electrical conductivity is sufficient.
CuproEL's durability is 5-6 times longer than electrolytic copper, that is, it allows to sinking five or six eyes instead of one eye with single electrode.
Although this rate varies depending on the work done, the biggest reason of our product Cupro Max (CuCrZr) got attention is it has better tooling ability than electrolytic copper.
In case of complex geometric machining to hardened steels or hard metals and high precision parts, TunCop 80/20, a tungsten alloy, can be used in sinking erosion electrodes with high expectations , such as fragile models and parts.
