Alloy		Density approx.	Composition in %	Important tempers	Tensile Strength R_m N/mm²	Yield Stress R_p0,2 N/mm²	Elongation A %	Hardness HV
CuSn6 DIN EN 12163 - 167 12449 1652 1654	CW452K	8,8	Sn 5,5 - 7,0 P 0,01 - 0,4 Cu bal.	Plates M H160 H180	*	*	*	* 160-190 180-210
Comparable Specifications: CuSn6, 2.1020, DIN 17662 C51900 UNS PB 103, BS 2870-2875 Good corrosion resistance and strength properties. Hard-wearing, good solderability. Good cold formability. Springs of all kinds, especially for the electrical industry. Applications in the paper, pulp and chemical industries, in shipbuilding and mechanical engineering.
CuSn8 DIN EN 12163 - 167 12449 1652 1654	CW453K	8,8	Sn 7,5 - 8,5 P 0,01 - 0,4 Cu bal.	Bars M R390 R450 R550 Tubes M R450	* ≥ 390 ≥ 450 ≥ 550 * ≥ 450	* ≤ 280 ≥ 280 ≥ 400 * ≥ 250	* ≥ 45 ≥ 26 ≥ 15 * ≥ 25	* *
Comparable Specifications: CuSn8, 2.1030, DIN 17662 C52100 UNS PB 104, BS 2870-2875 Better corrosion resistance than tin bronzes with lower tin content, higher strength and very good sliding properties and wear resistance. Good cold formability, good solderability. Sliding components, slide bearings (especially thin-walled ones) and sliding guides. Highly stressed worm and gear wheels, screws and bolts.
CuSn8P DIN EN 12163 12449	CW459K	8,8	Sn 7,5 - 8,5 P 0,2 - 0,4 Cu bal.	Bars M R390 R450 R550 Tubes M R460	* ≥ 390 ≥ 450 ≥ 550 * ≥ 460	* ≤ 280 ≥ 280 ≥ 400 * ≥ 280	* ≥ 45 ≥ 26 ≥ 15 * ≥ 30	* *
Like CuSn8. The increased phosphorus proportion is aimed at improving wear resistance and sliding properties still further.
