Copper Iron (CuFe) Master Alloy

The Copper-Iron master alloys are mainly used in the production of copper alloys, offering important savings in terms of dissolution time and energy compared with pure iron. In many cases the use of pure iron is not even feasible at all.

The Copper Iron master alloys have a solidus temperature of 1094 °C, hence they dissolve easily in a molten copper alloy. Iron improves the corrosion resistance and the resistance to impingement attack of copper nickel alloys. Iron acts as a grain refiner in brass.

In aluminium bronzes, iron refines the structure and has a beneficial influence on the mechanical properties, in particular on the tensile strength. Grainsize stabilised copper alloys with 2% iron are used in electrical engineering applications.
