1. A method of forming a composite component having a sintered copper alloy powder metal portion and a ferrous portion, the method comprising:
compacting a copper-containing powder metal to form an unsintered copper-containing powder metal compact, the copper-containing powder metal including copper and at least one alloying element; positioning the unsintered copper-containing powder metal compact adjacent to the ferrous portion; and sintering the unsintered copper-containing powder metal compact to form the sintered copper alloy powder metal portion, wherein the at least one alloying element of the copper-containing powder metal provides the sintered copper alloy powder metal portion with a material composition selected from the group consisting of bronze and brass; whereby, during sintering the unsintered copper-containing powder metal compact to form the sintered copper alloy powder metal portion, a dimensional change in the unsintered copper-containing powder metal compact results in an interference fit of the sintered copper alloy powder metal portion with the ferrous portion to join the sintered copper alloy powder metal portion and the ferrous portion together to form the composite component.
