Duralumin


Duralumin (also called duraluminum, duralum, duraluminium, duralium or dural) is the trade name of one of the earliest types of age-hardenable aluminium alloys. Its use as a trade name is obsolete, and today the term is mainly used to describe aluminium-copper alloys, designated as the '2000' series by the International Alloy Designation System (IADS).
