    Abstract: This disclosure is directed to copper-lead alloys for lubricants and bearings. The copper-lead alloys have a fine and even dispersion of the lead particles in a copper matrix. The alloy is made by adding an effective amount of a homogeneity promoter to a mixture of molten lead and copper. The promoter comprises elemental carbon and an alkali and/or alkaline earth metal compound capable of reacting to form a gas, or a rare earth metal compound in the form of an oxide or carbonate. The lubricants comprise the copper-lead alloy in powdered form, as a dry lubricant, in a carrier, or in a base of a grease or oil. The bearings comprise the copper-lead alloy as a load-bearing surface.
