This patent discusses a gold based electrical contact material comprising an oxide of an oxidizable element in the gold matrix formed by subjecting the solid solution to an oxidizing atmosphere for internally oxidizing the oxidizable element is presented. Such internal oxidation forms hard second phase oxide particles dispersed throughout the solution having high wear resistance, high hardness, high strength and high conductivity with homogeneous and uncontaminated structure.
