Recent Advances in the Technology of Aluminium- Magnesium Alloys

ALLOYS of aluminium with copper. to which smallamounts
of manganese. magnesium and silicon are added, belong
to the well known group of alloys termed "'Duralumin ', and were amongst the earliest of aluminium alloys to
be used commercially on account of their age-hardening characteristics.
Alloys of aluminium with magnesium as the principal
alloying element, first attracted the interest of
investigators as early as 1900, and since then, cast
alloys containing as much as 10% magnesium have
been used for specified purposes
