Alfred Wilm ( born June 25, 1869 in Lower Schellenberg, Silesia, † August 6, 1937 in Hall Mountain, Giant Mountains ) was a German chemist and metallurgist metallurgist.

Life

In 1901, Wilm was appointed as a metallurgist at the central office for scientific and technical studies in Neubabelsberg, where he was to do research on aluminum. In 1903, he filed his first patent on a "method for improving aluminum alloys by annealing and quenching " to. In 1906 he discovered the phenomenon by " swap space " hardening aluminum alloys. It is said that an apprentice in the laboratory have forgotten a Ausgießprobe over the weekend next to the furnace. The next Monday, they had a higher strength than on Saturday.

1909 A. Wilm announced a patent for a "method for refining of magnesium-containing aluminum alloys" to. The licenses for this purpose were soon purchased by the Duerener metal works, which marketed the product as duralumin. At the International Airship exhibition in Frankfurt in 1909, the new alloy was awarded the third prize at the airship exhibition 1910 in Petersburg the Great Silver Medal for the best airship material as well as the Grand Gold Medal for " advances in military technology ."

Soon asked many companies duralumin forth without the patent to be observed. Wilm overturned long with the infringers around, but his powers and royalties aufbrauchte so that he retired from his profession in 1919 and was a farmer. He remained there to his death. In 1937, he died on his Berghof mountain hall in the Giant Mountains.
