Use of Silicon Metal 421
Alloying agent (hardener) in iron and aluminum, the production of silicones, an addition to ceramics, welding rods, powder metallurgy, pyrotechnics, ammunition, ordnance, refractories, electronic substrates, cement, vapor deposition, plasma spray, chemical formulations, and grinding wheels.
Purpose of Silicon Metal 421
1. Use for Al alloy product: could be added in aluminum alloys, to enhance the strength of the alloy, increase its anti-oxidation and corrosion resistance, decrease its density and coefficient of thermal expansion, meliorate its casting performance, and make the alloy have a high impact resistance and pressure resistance.
2. Used for cold-rolled silicon steel product: After add silicon metal in steel, it could greatly improve the magnetic properties of steel, increase its permeability, reducing the hysteresis and eddy current losses.
3. Use for organic silicon product: silicone, silicon resin, silicone oil Silicone: Maintain flexibility in the range of-700℃ to 2000℃, could be used for high temperature gaskets and cold insulation materials. Silicon resin: For the production of insulating paint, heat temperature of 180 ~ 2000℃, can also be used for the production of high temperature coatings. Silicone oil: For the production of senior lubricant, polishing agent, fluid spring, and the dielectric liquid, also could be processed into a colorless transparent liquid, sprayed on the building for waterproofing. Silicon metal is more and more widely used in organic silicon industry, the usage amount is tend to exceed aluminum alloy industry.
4. Use for heat-resisting material product: For the production of Si3N4, heat-resistant, wear-resistant, and corrosion-resistant. Making the coated material can prevent oxidation. Siliconized steel surface can improve the corrosion resistance of the steel.
