Duralumin, strong, hard, lightweight alloy of aluminum, widely used in aircraft construction, discovered in 1906 and patented in 1909 by Alfred Wilm, a German metallurgist; it was originally made only at the company Dürener Metallwerke at Düren, Germany. (The name is a contraction of Dürener and aluminum.)
How is duralumin created?
Duralumin is actually a metal, which is an alloy of aluminum, copper, magnesium, and manganese. Duralumin is a special kind of metal and is made strong by subjecting it to heat treatment. It may be well spun, tempered, riveted, welded, or machinated.
Who was Alfred Wilm and what significant treatment for aluminum did he discover?
Whilst working in military research NUTZ in Neubabelsberg in 1901, Wilm discovered age hardening, in particular age hardening of aluminium alloys. This discovery was made after hardness measurements on Al-Cu alloy specimens were serendipitously found to increase in hardness at room temperature.
