863 Manganese Bronze


863 is a high strength manganese bronze or high tensile brass (HTB3). It is an exceptionally strong material that has higher hardness and strength ratings than even 304/316 stainless steel. 863 also has good wearing properties and good ductility, making it suitable for extra heavy duty slow speed bearings and for hydraulic cylinder components. Good lubrication is required for components made from 863. This material has reasonable corrosion resistance but de-zincification can occur under certain conditions.
