Magnesium ingots themselves are less used as structural components, and their core value lies in serving as raw materials for downstream processing.
Production of magnesium alloys: This is the main use of magnesium ingots. Magnesium ingots are fused with other metals (such as Al, Zn, Mn, Zr, RE, etc.) to produce various high-performance magnesium alloys. These magnesium alloys are widely used in:
Automotive industry: steering wheel frames, seat brackets, instrument panel brackets, transmission cases, cylinder head covers, etc. (weight reduction, energy conservation).
3C electronics: Notebook computer casings, mobile phone frames/back covers, camera bodies, projector casings, etc. (thin and light, heat dissipation, electromagnetic shielding).
Aerospace: aircraft seats, engine components, gearbox housings, missile components, etc. (ultimate weight reduction).
Tools and equipment: electric tool housings, chainsaw frames, sports equipment, etc.
Additives in aluminum alloy production: When smelting high-quality aluminum alloys, adding a small amount of magnesium can significantly enhance the alloy's strength, corrosion resistance and weldability.
Steel desulfurization: It serves as an efficient desulfurizer in the steelmaking process. Magnesium reacts with sulfur to form magnesium sulfide slag, which can significantly reduce the sulfur content in steel and improve the quality of steel (enhancing toughness and weldability).
Ductile iron production: As a spheroidizing agent added to molten iron, it causes graphite to precipitate in spherical form, greatly enhancing the strength, plasticity and toughness of cast iron.
Chemical reduction: Reducing agents for the production of rare metals such as titanium, zirconium, hafnium and uranium; Produce Grignard reagents.
Fireworks manufacturing and flares: Utilizing the property of magnesium powder to produce dazzling white light when burning.
