The solubility of magnesium is very high in aluminium and reaches a maximum at 450 °C with 14% to 17% depending on the literature reference. At 34.5%, there is a Eutectic with Al 8 Mg 5 (sometimes referred to as Al 3 Mg 2), an intermetallic phase (-phase).
Alloys with small amounts of magnesium (about 5%) exhibit greater strength, greater corrosion resistance, and lower density than pure aluminium. Such alloys are also more workable and easier to weld than pure aluminum. [1] Alloys with high amounts of magnesium (around 50%) are brittle and more susceptible to corrosion than aluminum.
Marking AZ91A for example conveys magnesium alloy with roughly 9 weight percent aluminium (between 8.6 and 9.4) and 1 weight percent zinc (between 0.6 and 1.4), and the final A means it was the first alloy with this composition at the time of registration. Exact composition should be confirmed from reference standards.

The content of magnesium is greater than that of silicon, otherwise they belong to the aluminum–silicon–magnesium alloys (AlSiMg). AlMgSi is one of the hardenable aluminum alloys, i.e. those that can become firmer and harder through heat treatment. This curing is largely based on the excretion of magnesium silicide (Mg 2 Si). The AlMgSi ...
5083 aluminium alloy is an aluminium–magnesium alloy with magnesium and traces of manganese and chromium. It is highly resistant to attack by seawater and industrial chemicals. [1] Alloy 5083 retains exceptional strength after welding.
There are several different formulations of magnesium supplements on the market, but let’s consider two of the most commonly used kinds: magnesium citrate and magnesium glycinate. These two are ...
5052 is an aluminium–magnesium alloy, primarily alloyed with magnesium and chromium. 5052 is not a heat treatable aluminum ... Magnesium - 2.2%-2.8% by weight;
