High-purity silicon metal in multiple grades for the aluminum, semiconductor, chemical and solar industries.
Metallic silicon — also known as crystalline silicon or industrial silicon — is a non-metallic element with a characteristic blue-gray, metallic appearance. It is hard, brittle and one of the most widely used industrial materials in the world.
AL-LINX supplies silicon metal in multiple industrial grades, sourced directly from our certified manufacturing facility in Anyan, China — a leader in silicon production and processing. Our close factory relationships mean consistent quality, competitive pricing and the ability to meet custom specifications.
We supply all major industrial silicon grades with full documentation and CoA. Custom sizing and packaging available on request.
