Current Practice in aluminium plate Forming
* Cold forming-- forming at room temperature
* Warm forming-- forming at elevated temperature (<350℃)
The formability of aluminum alloys increases with increasing
temperature and decreasing strain rate.
The blank( and sometimes the dies) should be heated.
More complex tools are required and insulation is necessary if the
dies are heated.
Cycle time is longer than cold forming due to heating process.
Lubricants that perform well at elevated temperatures should be
used.
Springback is reduced.
Density, Elastic modulus and anisotropy of aluminum vs. That of
steel
* The density of aluminum(2.7g/cm3) is one third of
steel(7.85g/cm3), Thus, weight can be reduced.
* Elastic modulus of aluminum(70 Gpa) is one third of steel
(210Gpa). As a result, the parts previously designed for steel need
to be redesigned to achieve the same stiffness.

UTS(Mpa) | 270 | 450 | 800 | 1520 | 130 | 245 | 430 |
* Smaller elastic modulus also results in more springback
compensation(assuming the strengths are the same).
* Anisotropy values are lower than steel.
