An aluminum thrust washer (10) that has a wrought aluminum matrix (38) that includes from 2 to 20 weight percent silicon, 0.1 to 4 weight percent of copper, with the remainder pure aluminum. The aluminum thrust washer is formed of a mono-metal structure without a backing layer. The wrought aluminum matrix has mechanical properties such that the aluminum matrix wears away, leaving silicon particles (36) exposed at a thrust face of the washer, such that the density of the silicon particles (36) is continually increasing as the thrust washer is utilized.
