Uses of silicon metal grade 441 553 3303

Silicone oil is an oily substance whose viscosity is little affected by temperature. It is used to produce high-grade lubricants, polishes, fluid springs, dielectric liquids, etc. It can also be processed into a colorless and transparent liquid and sprayed on the surface of buildings as a high-grade waterproofing agent.

Manufacturing high-purity semiconductors

Modern large-scale integrated circuits are almost all made of high-purity silicon metal, and high-purity silicon metal is also the main raw material for the production of optical fibers. It can be said that silicon metal has become the basic pillar industry of the information age.

Silicon-aluminum alloy is the most widely used silicon alloy. Silicon-aluminum alloy is a strong composite . Replacing pure aluminum in the steelmaking process can improve the utilization rate of the deoxidizer, purify molten steel, and improve the quality of steel. Silicon-aluminum alloy has a low density, low thermal expansion coefficient, good casting performance and wear resistance. The alloy castings cast with it have high impact resistance and good high-pressure density, which can greatly improve the service life. It is often used to produce aerospace vehicles and automotive parts.

Silicon-copper alloy has good welding performance, is not easy to generate sparks when impacted, has explosion-proof function, and can be used to make storage tanks.
