Factory Price Sale High Grade Silicon Metal 441/421/553/2202/3303 For Steelmaking Additives
What is metal silicon?
Silicon metal manufacturing process
1.In China, Silicon metal lump is widely used in smelting alloy
elements,as a reducing agent in many kinds of metal smelting.
2.Silicon metal lump widely applied to refractory material and
power metallurgy industry to improve the heat resistance, wear
resistance and oxidation resistance.
3. Silicon powder is regarded as alloy additive, improve the steel
hardenability in metallurgy and foundry industry.
4.It is mainly used in production of alloys,polycrystalline
silicon,organic silicon materials and high-grade refractor .

Silicon metal uses
Mainly used in the steel industry and foundry industry.
1. Used in aluminum: An additive to aluminum alloys, silicon is
used to increase the fluidity and tenacity of Aluminum and its
alloys, which enjoy good castability and weldability accordingly.
2. Used in organic chemicals: Silicon metal lump is used in
manufacturing a number of sorts of silicones, resins, and
lubricants.
3. Used in electronic parts: Silicon metal lump is used in
producing monocrystalline and polycrystalline silicon of high
purity for electronic parts, such as semi conductors, etc.
