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.
