Cast High Lead Bronze
(Copper-Lead-Tin cast alloys)
DIN 1716 bzw. DIN EN 1982

Alloy	EN number	Density ca.	Composition in % of weight	Properties and use
CuSn10Pb10-C DIN EN 1982	CC495K	9.0	Cu 78,0 - 82,0 Sn 9,0 - 11,0 Pb 8,0 - 11,0	Bearing material with good sliding and dry-running properties. Good corrosion resistance and good to moderate wear resistance, suitable for high surface pressures. Very good machinability.

Important tempers	Tensile Strength R_m N/mm²	Yield Stress R_p0,2 N/mm²	Elongation A %	Hardness HB
GC GZ	≥ 220 ≥ 220	≥ 110 ≥ 110	≥ 8 ≥ 6	≥ 70 ≥ 70
Product with information obligations to REACH-Legislation
Comparable Specifications:: CuPb10Sn, 2.1176, DIN 171 C93700 UNS LB 2, BS 1400

Alloy	EN number	Density ca.	Composition in % of weight	Properties and use
CuSn7Pb15-C DIN EN 1982	CC496K	9.1	Cu 74,0 - 80,0 Pb 13,0 - 17,0 Sn 6,0 - 8,0 Ni 0,5 - 2,0	Soft bearing material with very good sliding and dry-running properties when there is a sporadic lack of lubricant and with water lubrication. Bearings with very high surface pressures in which high edge pressure can occur. Unsuitable for temperatures above 120 °C. Resistant to sulphuric acid. Very good machinability.

Alloy	EN number	Density ca.	Composition in % of weight	Properties and use
CuSn5Pb20-C DIN EN 1982	CC497K	9.3	Cu 70,0 - 78,0 Pb 18,0 - 23,0 Sn 4,0 - 6,0 Ni 0,5 - 2,5	Very soft bearing material with excellent sliding and dry-running properties when there is a sporadic lack of lubricant and with water lubrication. But problematic with casting and rarely commercially available. For this reason usually replaced with Cu Sn7 Pb15-C.
