Fire-damaged Duralumin cross brace from the Zeppelin airship Hindenburg (DLZ129) salvaged from its crash site at Lakehurst Naval Air Station, NJ on May 6, 1937 Corrosion of duralumin. Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age-hardenable aluminium ...
[1] [2] In older systems of terminology, 2XXX series alloys were known as duralumin, and this alloy was named 24ST. 2024 is commonly extruded, and also available in alclad sheet and plate forms. It is not commonly forged (the related 2014 aluminium alloy is, though).
Duralumin is the oldest variety in this group and goes back to Alfred Wilm, who discovered it in 1903. Aluminium could only be used as a widespread construction material thanks to the aluminium-copper alloys, as pure aluminium is much too soft for this and other hardenable alloys such as aluminium-magnesium-silicon alloys (AlMgSi) or the ...
Duralumin (copper, aluminium) Hindalium (aluminium, magnesium, manganese, silicon) product of Hindustan Aluminium Corporation Ltd, made in 16ga rolled sheets for cookware; Lockalloy is an alloy that consists of 62% beryllium and 38% aluminium.
AA-8000: used for electrical building wire in the U.S. per the National Electrical Code, replacing AA-1350. [1] Al–Li (2.45% lithium): aerospace applications, including the Space Shuttle; Alnico (nickel, cobalt): used for permanent magnets; Aluminium–Scandium ; Birmabright (magnesium, manganese): used in car bodies, mainly used by Land ...
Like duralumin, this was a 4% copper alloy, but with the addition of 2% nickel and 1.5% magnesium. [4] This addition of nickel was an innovation for aluminium alloys. These alloys are one of the three main groups of high-strength aluminium alloys, the nickel–aluminium alloys having the advantage of retaining strength at high temperatures.
At the time Wilm was developing an aluminium alloy to replace brass in ammunition. The patent on Duralumin was ignored and breached by many firms, and he struggled without success to protect his rights under it. In 1919, Wilm retired from research and became a farmer. He died at his farm in Saalberg on 6 August 1937. [2] [6] [7]
Following the all-metal Silver Streak of 1920, Short Brothers produced a series of military aircraft with duralumin monocoque fuselages and wings which were at first duralumin covered, then fabric. [1] The last of this series was the Short S.6 Sturgeon, a three-seat fleet reconnaissance aircraft designed to meet Air Ministry specification 1/24 ...
