Silicon metal is also called industrial silicon or crystalline silicon, metallic gray, hard and brittle. Silicon metal has attributes such as high melting point, excellent heat resistance, high resistivity, and strong anti-oxidation.
We own five 12500KVA silicon furnace,withannual silicon metal production capacity of 50,000 tons. The main silicon grade including 2202, 2502, 3303, 411, 421, 441, 553,etc., which are widely used in variety of industries,such as, aluminum alloy,organosilicone, ploysilicon, electronics, refractory materials and so on.
