供应Silicon metal (Si Metal), also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is smelted from silica and carbonaceous reducing agents in a submerged arc furnace. It is an important industrial raw material. The main component is silicon, and other impurities are iron, aluminum, calcium, etc. Silicon metal can be used for steelmaking, cast iron, and aluminum (production of iation, aircraft and automobile parts). Industrial silicon is purified through a series of processes to produce polycrystalline silicon and monocrystalline silicon for use in the photovoltaic industry and the electronics industry. Due to its wide application, Silicon metal is known as the “salt” of modern industry

Silicon metal lumps are produced from quartz and coke in an electric heating furnace. Quartz will undergo oxidation and reduction and become molten silicon liquid. Once cooled, it will turn into a solid as we can see. The chunks of raw silicon metal are very large. It is then made into smaller pieces, which we call standard sizes. The size of silicon metal lumps i0-100mm， silicon metal powder (particle size 100, 200, 325 mesh).

Silicon can be alloyed with other metals to enhance its metallic properties. Alloys made of silicon mainly include: silicon aluminum alloy, silicon copper alloy, ferrosilicon alloy, silicon manganese alloy, etc. The presence of silicon elements in silicon-aluminum alloy can improve the fluidity of the alloy, reduce the tendency of hot cracking, reduce porosity, and improve air tightness. This type of alloy has good corrosion resistance and moderate machinability, has medium strength and hardness, and has low plasticity. It is used to manufacture castings with low and medium strength and complex shapes, such as cover plates, motor casings, and brackets. etc., also used as brazing solder.
