3.1655 (DIN 1725-1 : 1983-02) 3.1655 DIN 1725-1 : 1983-02 DIN 1725-1 : 1983-02 replaced by DIN EN 573-3 : 2003-10 and DIN EN 573-4 : 2004-05 Replaced Germany EN AW-Al Cu6BiPb 2.1 1)
1) Remark: The material AlCuBiPb is a free-cutting alloy (boring and turning quality). Because of the splinter-breaking alloying elements Bi and Pb, it is especially suitable for machining (particularly fine splinter). This alloy is hot and cold hardenable. Strength grade can be achieved by the appropriate heat treatment by F 28 to F 37. In the strength grade F 37 (hot-hardened) strength and cutting property are optimal, and turned parts can be worked on during high cutting performance with high dimensional accuracy and small surface roughness. A surface treatment is always recommended with corrosive attack which can be expected, because the corrosion resistance under certain conditions is insufficient. Anodising for decorative purposes is not possible. Welding is conditionally possible, but because of the hot cracking danger and the serious strength waste, its employment is not recommendable in welded structures. The alloy AlCuBiPb is standardised only as bar and pipe (DIN 1747 part of 1 and/or part of 2 and DIN 1746 part of 1 and/or part of 2). Heat treatment for hardening: solution annealing: 515 to 525 °C, quenching in water to 65 °C cold ageing: 5 to 8 d at ambient temperatures hot ageing: 8 to 16 h at 165 to 185 °C Application: In the automobile engineering for brake piston, clutch parts in brake systems, turned parts for tax aggregates, parts for pneumatic suspensions, core material for flexible motor attachments, parts of liquefied petroleum gas tanks, speedometer parts, valve spools for automatic clutches, transmission axles generally for operating sectors in mechanical engineering axles for photocopying machines, coupling plug (television sets), cylindrical fuseholders, turned parts at the percussion drill and/or for seismometer, coils for fishing rod linen and/or spinning machines, housings and valve spools for pneumatics and hydraulic pistons and for lugs.
