Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a strong, lightweight alloy of aluminium discovered in 1910 by Alfred Wilm, a German metallurgist. Aluminium alloys of 2000 series are alloyed with copper, they can be precipitation hardened to strengths comparable to steel.
