The thickness of a typical aluminium plate is at least 0.25 inches. Soft aluminium is much more ductile than several high-strength materials. Owing to its high ductility, aluminium can be bent into very sharp radii. Relatively hard aluminium samples are known to have lower ductilities when compared to its soft form. However, it is important to note that aluminium retains its plasticity at extremely low temperatures. It can be bent even at temperatures as low as -270oC. Therefore, aluminium can be bent at any temperature.
Aluminium is often bent at room temperatures. The precision of the aluminium fixtures can be increased by machining the aluminium (and its alloys). Bending of aluminium at relatively high temperatures (in the range of 660 to 700 oC) is not very cost-efficient. However, these temperatures enable the casting of several high-resistance alloys of aluminium in many complex shapes. Thus, ambient temperatures are the most efficient temperatures at which aluminium can be bent.
