General fabrication properties of the various alloy series are given in the Table below.
For non-heat treatable alloys additional strength is imparted on the alloy by work hardening. The alloy can then be softened to the desired properties by heating in an annealing stage.
For heat treatable alloys, strength is imparted by heating followed by quenching and ageing. Quenching is a rapid cooling process using air or water.
1XXX Excellent formability, weldability and corrosion resistance. Low strength
2XXX Excellent machinability & high strength. Poor formability, weldability & corrosion resistance
3XXX Formable, corrosion resistant and weldable. Moderate strength
4XXX Formable, weldable, corrosion resistant
5XXX Formable, weldable, excellent corrosion resistance
7XXX Machinable, poor corrosion resistance & weldability. High strength
8XXX Excellent formability
