Magnesium ingots are mainly used to make magnesium alloys.

At present, the most widely used magnesium alloys are magnesium-aluminum alloys, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. Mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors. It is the lightest metal in practical use, and the specific gravity of magnesium is about 2/3 of that of aluminum and 1/4 of that of iron. It is the lightest metal among practical metals, with high strength and high rigidity. Magnesium ingot is a new type of lightweight corrosion-resistant metal material, with low specific gravity, high strength per unit weight, and high chemical stability. It is widely used in automobile manufacturing, light industry, metallurgical industry, chemical industry, electronics industry and instrument manufacturing.
