Aluminium-magnesium alloys are considered to be very corrosion-resistant, making them suitable for marine applications, but this is only true if the -phase exists as a non-contiguous phase. Alloys with Mg contents below 3% are therefore always corrosion-resistant, with higher contents, appropriate heat treatment must ensure that this phase is ...
Magnesium provides advantages over aluminium, in being of even lower density (≈ 1.8 g/cm 3) than aluminium (≈ 2.8 g/cm 3). [15] The mechanical properties of magnesium alloys tend to be below those of the strongest of the aluminium alloys. [16]
T651 temper has similar mechanical properties. The typical value for thermal conductivity for 6061-T6 at 25 °C (77 °F) is around 152 W/m K. The fatigue limit under cyclic load is 97 MPa (14 ksi) for 500,000,000 completely reversed cycles using a standard RR Moore test machine and specimen. [ 12 ]
5052 is an aluminium–magnesium alloy, primarily alloyed with magnesium and chromium. 5052 is not a heat treatable aluminum alloy, but can be hardened through cold working. [ 2 ] Chemical properties
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.
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.
