Elmedur® Hard Copper Alloys for Tool- and Mould-Making

Characteristic of copper materials is their high thermal conductivity. Regarding the cooling of plastic moulds, their advantage over steel is the possibility of a controllable cooling process in case of material accumulations.

The good thermal fatigue resistance of Duro Metall copper alloys is exploited in ingot mould making for non-ferrous metal casting.

When our materials are used as FE electrodes, the high modulus of elasticity reduces the oscillation of the electrodes in the erosion gap, thereby enabling tighter die sinking tolerances. Thin root faces are less sensitive to handling errors and mechanical damage.
