Bronze Round Bar 630 contains a high amount of nickel and aluminum, giving it an exceptionally high strength, as well as high wear resistance, corrosion resistance, and ductility. Additionally, 630 maintains its strength even at elevated temperatures and for prolongued periods. It is typically used in aerospace and marine applications such as valve stems, high strength bushings, valve seats and guides, gears, cams, nuts, shafts, and ship propellers.
