Magnesium

[AucontraireII]

Is one of the most corrosion susceptible metals in the periodic table. This is usually handled by using surface treatments to prevent surface corrosion and by alloying with other metals. But it's even more corrosion susceptible than aluminum. So corrosion resistance is a disadvantage of magnesium, really only it's light weight and ability to alloy with other metals and still be reasonably strong give it advantage.

Corrosion of magnesium alloys increases with relative humidity. At 9,5% humidity, neither pure magnesium nor any of its alloys exhibit evidence of surface corrosion after 18 months. At 30% humidity, only minor corrosion may occur. At 80% humidity the surface may exhibit considerable corrosion. In marine atmospheres heavily loaded with salt spray, magnesium alloys require protection for prolonged
