Stronger and Lighter Than Aluminium.
British scientists in the Metallurgy Department of the National Physical Laboratory at Teddington have developed two important new teries of light alloys of magnesium, which will be of great importance in the production of aircraft, Magnesium alloys are lighter than those of aluminium, but hitherto have lacked their strength. This has been the main obstacle to their greater use.
The report states that one of the new series of alloys containing magnesium, with small amounts of aluminium, silver and other metals, has greatly increased strength of Ordinary temperatures, and is considerably lighter than good aluminium alloys. The second series, containing cerium—a rare metallic element—and small próportions of other metals, retain their strength at high temperatures better than the light alloys previously in use,
