Al-Bronze・Al-Ni-Bronze・Bronze
Yamato Gokin offers a wide range of aluminum bronze alloys. The first of our aluminum bronze alloys was developed by company 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. For our aluminum bronze material, we have two manufacturing processes: extrusion and forging, and mainly manufacture them as bars and pipes/hollow bars. Our aluminum bronze material is mainly used for landing gear bushings and bearings.
