A high strength aluminum bronze alloy consisting essentially of 8.0 to 11.8 percent aluminum, 0.05 to 2.0 percent zirconium, 0.5 to 4.0 percent cobalt, 0.1 to 2.0 percent manganese, balance essentially copper, wherein the alloy has a metallographic structure containing 5 to 100 percent beta phase, remainder alpha phase, with a uniformly fine metallographic grain structure with a grain size of less than 0.065 mm., and a method of obtaining exceptional formability in these alloys.
