Silicon Metal & Aluminum Technology FAQs

What is silicon metal and how is it used in aluminum alloys? +

Silicon metal is a high-purity form of silicon (typically 98-99.9% Si) used as an alloying element in aluminum production. When added to molten aluminum, it improves fluidity, reduces shrinkage, and enhances overall casting properties. Learn about our silicon metal grades optimized for aluminum ingot production.

What are the main silicon metal uses in the aluminum industry? +

Silicon metal is primarily used to produce aluminum-silicon alloys (like A356, A357) for automotive and aerospace castings. It also improves grain refinement when used with ferro silicon inoculants. For tailored solutions, request a custom quote from our experts.

How does silicon metal improve aluminum ingot quality? +

Adding silicon metal to aluminum increases strength and hardness while reducing thermal expansion. Proper silicon content (usually 7-12% Si) also minimizes hot cracking and porosity in ingots. Read our article on silicon content in aluminum alloy ingots for detailed guidance.
