Metallurgical Silicon – The Foundation of Advanced Aluminum Alloys
Metallurgical silicon (MG-Si), with a purity range of 98.5–99.5%, is the backbone of aluminum alloy production. Produced via carbothermic reduction of quartz in electric arc furnaces, its high silicon content enhances alloy strength, corrosion resistance, and thermal stability. Key applications include:
Automotive alloys: Adding 7–12% Si reduces engine component weight by 20% while maintaining durability (e.g., ASTM B85 standards).
Aerospace alloys: High-purity Si (Fe < 0.4%, Al < 0.2%) prevents micro-cracking in turbine blades under extreme temperatures.
Packaging foils: Silicon-modified aluminum alloys improve formability for food-grade packaging.
Technical Specifications: Our MG-Si is available in multiple grades:
Standard Grade (98.5% Si): Lump size 10–100mm for foundry applications.
Ultra-Refined Grade (99.5% Si): Low boron (<10ppm) and phosphorus (<15ppm) for solar polysilicon feedstock.
Nodularized Si (2–5mm granules): Pre-alloyed with strontium for rapid dissolution in molten aluminum.
