Silicon Metal 421 grade
Metal silicon is a kind of industrial pure silicon, which is mainly used in the production of organic silicon, the preparation of high-purity semiconductor materials and the preparation of alloys for special purposes.
Silicon aluminum alloy is the most widely used silicon alloy. Si Al alloy is a kind of strong Compound Deoxidizer. It can improve the utilization rate of deoxidizer, purify liquid steel and improve the quality of steel.
Silicon aluminum alloy has low density, low coefficient of thermal expansion, good castability and wear resistance. The alloy castings cast with silicon aluminum alloy have high impact resistance and good high pressure density, which can greatly improve the service life.
