High Purity Si Metal 441 Lump

Silicon Metal is processed by excellent industrial silicon and including full varieties. It is silver gray or dark gray with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance. Metal Silicon is a very important industrial product can be used in steel-making, cast iron, silicon optoelectronic device and many other industries. The silicon metal lumps also can be further processed into higher purity silicon and then used as an additive in aluminum alloy ingot smelting, steel production, aluminum alloy production, and electronic component production.
