The copper-indium-gallium (CuInGa) alloy is in particular to be used for the production of sputter targets, tubular cathodes and similar coating material sources. It has a phase corresponding to a Cu5Zn8 prototype phase in which the lattice sites of the zinc atoms (Zn) are occupied by gallium atoms (gallium-substituted Cu5Zn8 phase) and in which indium is simultaneously introduced into the elementary cell or phase, making up a proportion of up to 26 wt %.
