Magnalium is an aluminium alloy with magnesium and small amounts of copper, nickel, and tin. Some alloys, intended for particular uses at the cost of poor corrosion resistance, may consist of up to 50% magnesium. It finds use in engineering and pyrotechnics. ==Properties== Alloys with smaller amounts of magnesium (about 5%) exhibit greater strengt...

Magnalium is an alloy of magnesium and aluminium, in forming which the air is excluded when the metals are melted together and the mass is cooled down in a vacuum or under high pressure (100-200 atmospheres). The metals may be in various proportions, the properties of the alloy differing accordingly, so that it may be either brittle or very extensi...
