Audited Supplier A91100 is one of the widest used alloys, with excellent forming properties in annealed states and may be suitable for bending, spinning, drawing, stamping, roll forming, and many other applications.
A91100 Aluminium alloy is an aluminium-based alloy in the "commercially pure" wrought family (1000 or 1xxx series). With a minimum of 99.0% aluminum, it is the most heavily alloyed of the 1000 series. It is also the mechanically strongest alloy in the series. At the same time, it keeps the benefits of being relatively lightly alloyed (compared to other series), such as high electrical conductivity, corrosion resistance, and workability. It can be strengthened by cold working, but not by heat treatment.
Alternate designations include Al99.0Cu and A91100. 1100 and its various tempers are covered by the ISO standard 6361 and the ASTM standards B209, B210, B211, B221, B483, B491, and B547.
A91100 is known to have very good machinability, and the best results are obtained when machining in the hard temper. Carbide tooling is preferred, but high speed steel tooling can also be used.
