A continuous cast high leaded tin bronze to BS1400 LB5 CuPb20Sn5, meeting the requirements of BS EN 1982-2008 CC497K CuSn5Pb20-C. This very high leaded bronze is ideal for a wide range of bearing applications, especially where there could be a loss of the lubrication boundary. This range of alloys performs excellent in unforgiving environments where foreign matter may be present such as dust and dirt, and the ability to lubricate is an issue.
