C86300 High-Strength Manganese Bronze, also known as SAE 430B, offers some of the highest mechanical properties available in cast bar. C863 Manganese Bronze has good corrosion and wear resistance and is well suited for applications involving high loads and low speeds. C86300 Bronze is available as centrifugal cast, continuous cast and sand cast bar. CDA 863 Manganese Bronze is ideally suited for heavy duty applications, including bridge pins, bushings, wear rings, clamps hydraulic cylinder parts and rudders.
Available in round, tube & rectangle. Also cast to size.
