Overview
Manganese Bronze 863 is a high strength 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.
863 manganese bronze (C86300) is supplied across New Zealand and Australia — cast to order (indent) for heavy-load applications.
