Silicon Metal 441 10-50 mm Lumps
441 Silicon Metal Description
441 Silicon Metal
Silicon Metal 441 is a non-ferrous metal alloy with a hexagonal crystal structure, renowned for its high thermal conductivity (148 W/m·K), low toxicity, and resistance to acids and alkalis. In metallurgy, it is alloyed with magnesium to create magnesium-silicon alloys for aerospace components, where a 10% silicon addition increases strength by 30% without compromising ductility.
We operate as a direct manufacturer, eliminating markups and offering free samples, technical manuals, and certified test reports (lab and industry) to help you select the right grade (441, 553, etc.) for your application.
With 30+ years of expertise, 1.5 million tons annual capacity, and 300 skilled employees, we maintain large inventories to ensure timely delivery and customize products (e.g., alloy grades, packaging) to your exact specifications.
Quality is non-negotiable: every order undergoes ≥4 spectral/chemical tests-including raw material screening, in-production batch checks, and final product validation-to meet ASTM, RoHS, and customer-specific criteria, ensuring consistent, reliable supply.
We prioritize your peace of mind: our metal silicon is packaged in 10kg/25kg waterproof bags within 1MT bulk sacks (or custom formats) to prevent moisture damage, while our dedicated account managers provide real-time order updates, and our after-sales team addresses concerns within 24 hours, ensuring your satisfaction.
