Fremgangsmåte for å forbedre korrosjonsmotstanden for magnesium-aluminium-silisiumlegeringer og magnesiumlegering medforbedret korrosjonsmotstand

摘要

Magnesium alloy with improved corrosion resistance comprising magnesium, 1.5-5 weight % Al, 0.6-1.4 weight % Si, 0.01-0.6 weight % Mn and 0.01-0.4 weight % RE. Method of improving the corrosion resistance of magnesium, aluminium, silicon alloys where Mn is added in order to reduce FE impurities, by keeping both Mn and Fe at a low level by adding small amounts of RE.
