Schreier Metall GmbH: Cast High Lead Bronze

Cast High Lead Bronze

Alloy			Density approx.	Composition in %	Important tempers	Tensile Strength R_m N/mm²	Yield Stress R_p0,2 N/mm²	Elongation A %
CuSn10Pb10-C DIN EN 1982	CC495K	9,0	Cu 78,0 - 82,0 Sn 9,0 - 11,0 Pb 8,0 - 11,0	GC GZ	≥ 220 ≥ 220	≥ 110 ≥ 110	≥ 8 ≥ 6	≥ 70 ≥ 70
Comparable Specifications: CuPb10Sn, 2.1176, DIN 1716 C93700 UNS LB 2, BS 1400 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. Product with information obligations to REACH-Legislation
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	GC GZ	≥ 200 ≥ 200	≥ 90 ≥ 90	≥ 8 ≥ 7	≥ 65 ≥ 65
Comparable Specifications: CuPb15Sn, 2.1182, DIN 1716 C93800 UNS LB 1, BS 1400 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.

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	GC	≥ 180	≥ 90	≥ 7	≥ 50
Comparable Specifications: CuPb20Sn, 2.1188, DIN 1716 C94100 UNS LB 5, BS 1400 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. Product with information obligations to REACH-Legislation
