\u00a0 \u00a0 \u00a0 3A21 ist eine Legierung auf Al-Mn-Basis, die sich hervorragend als rostfreie milit\u00e4rische Aluminiumlegierung eignet. 3A21-Aluminiumblech ist ein weit verbreitetes rostfreies Aluminium mit geringer Festigkeit (nur geringf\u00fcgig h\u00f6her als industrielles Reinaluminium) und kann nicht durch W\u00e4rmebehandlung verst\u00e4rkt werden. Daher werden h\u00e4ufig Kaltverarbeitungsmethoden eingesetzt, um die mechanischen Eigenschaften zu verbessern. Es hat eine hohe Plastizit\u00e4t im gegl\u00fchten Zustand, und es ist immer noch gut, wenn geh\u00e4rtet halb gek\u00fchlt arbeiten, geringe Plastizit\u00e4t w\u00e4hrend der H\u00e4rtung, gute Korrosionsbest\u00e4ndigkeit, gutes Schwei\u00dfen, und schlechte Schneidleistung.<\/span><\/p>\n
