As the metals industry evolves, we are witnessing a rise in demand for special copper alloys with more strenuous requirements. To meet our customers' needs, we've developed several aluminum bronze alloys with excellent mechanical properties. The first of these was developed by our founder, Dr. Shigeru Hagino, when he was with Mitsubishi Steel Manufacturing in the 1940s. His aluminum bronze would make a major impact in the industry over the next 70 years, and marked the start of Yamato Gokin's history as a special copper alloy manufacturer.
