Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Successor
2.1090 (DIN 1705 : 1981-11)	2.1090	DIN 1705 : 1981-11	DIN 1705 : 1981-11 replaced by DIN EN 1982 : 1998-12	Replaced	Germany	CuSn7Zn4Pb7-C	1)
1) Remark: G-CuSn7ZnPb (former Rg7) is a medium hard material for slide bearings. It has good dry-running operation properties and is resistant against sea water. It is used in machine engineering (allowed are max. loads up to 4000 N/cm^2) for slide bearings and coupling rods, for moderate stressed sliding plates, sockets (when the axe is made of surface annealed steels), for piston pins up to 4000 N/cm^2... Machining properties: Grindability: very good Soft soldering: good Hard soldering: restricted Gas fusion welding: poor Gas-shielding welding: poor Grindability (mech): good Galvanisability: good Immersing tin-plating: good
