Definitions
- the invention relates to an aluminum alloy according to the preamble of claim 1.
- Wrought alloys suitable as machine materials on the Basis AlCu and AlMgSi contain as a chip-breaking additive Lead, possibly in combination with bismuth. Alloys of this type are designated according to EN 573: 1994 as follows: EN AW-AlCu6BiPb, possibly EN AW-AlCu6BiPb (A) and EN AW-AlMglSiPb, EN AW-AlMglSiPbMn, possibly EN AW-AlMgSiPb.
- the inventor has the Task, a suitable as a machine material, to provide lead-free aluminum alloy with good machinability, compared to conventional machine materials comparable or better mechanical properties having.
- the preferred range lies in the alloy according to the invention for tin at 0.7 to 1.0, preferably 0.7 to 0.9% by weight, the preferred range for bismuth at 0.3 to 0.6, in particular 0.4 to 0.6, the preferred range for copper at 0.15 to 0.40, and the preferred range for titanium is 0.04 to 0.10% by weight.
- the alloy according to the invention can be made in a known manner through semi-continuous casting and extrusion are processed. Usually they become semi-continuous continuously cast ingots subjected to an annealing; however, this can also be omitted. The extruded Products are then subjected to a heat treatment or thermomechanical processing in various final states transferred.
