The present disclosure provides a method of manufacturing a composite material. The method can include compacting a copper alloy powder into a plurality of substantially uniform compressed sub-assemblies such that the copper alloy powder has a density that is greater than 50%. The plurality of compressed sub-assemblies can be layered relative one another within an aperture of a shell, the plurality of compressed sub-assemblies to form a consecutive assembly of compacted copper alloy. The shell may include one of the following: a precipitation hardened copper alloy, copper alloy, and carbon steel. The consecutive assembly can be sealed within the shell to form a billet. The billet can be hot-extruded to form a rod, and the extruded rod can be further drawn to form a composite wire of a desired diameter. The composite wire may be used to create a composite welding electrode.
