Aluminium and its alloys
Published in William Bolton, R.A. Higgins, Materials for Engineers and Technicians, 2020
The commercial grades of aluminium (1200) are sufficiently strong and rigid for some purposes, and the addition of up to 1.5% manganese (3103) will produce a stronger alloy. The aluminium-magnesium alloy with 1.2% manganese and 1% magnesium (3004) is used for beverage cans. It combines strength with ductility to make it possible to deep-draw the cans. The aluminium-magnesium alloys have a very good resistance to corrosion, and this corrosion-resistance increases with the magnesium content, making them particularly suitable for use in marine conditions (Table 17.6). The aluminium-magnesium alloy with 4.5% magnesium and 0.35% manganese (5182) is used for the lids of beverage cans since it is harder than 3004 and so more able to withstand the forces involved with ring pulls.

Wrought aluminium alloys are also produced with a wide range of compositions. In the classification scheme adopted by many countries and described in BS EN 573, these are divided into eight series depending on the principal alloying element: 1000 series: ≥99% pure aluminium2000 series: aluminium–copper alloys3000 series: aluminium–manganese alloys4000 series: aluminium–silicon alloys5000 series: aluminium–magnesium alloys6000 series: aluminium–magnesium–silicon alloys7000 series: aluminium–zinc–magnesium alloys8000 series: miscellaneous alloys.

The quest for lighter and stronger materials has triggered interest in aluminium alloys as a substitute for steels in body panels of automotives. Aluminium-magnesium alloys are potential candidate for many structural applications because of their low density. These alloys have been investigated for quite some time in order to render them suitable for specific applications as these materials exhibit reasonable strength along with good corrosion resistance. Further, Al–Mg alloys could be the model materials for examining the effect of change in stacking fault energy on the evolution of texture and microstructure.
