Unveiling the Versatility of Silicon Metal 421

Silicon metal 421 is an alloy made by smelting coke and quartz (or silica) as raw materials through electric furnace. The main ingredient silicon content is about 98%, and the rest of the impurities are iron, aluminium, calcium and so on.
Silver grey or dark grey lump, high melting point, good heat resistance, high resistivity, excellent oxidation performance
Resistance. It is called “industrial glutamic acid”, which is indispensable in high-tech industry. It has good chemical properties and is widely used in industry.

Product category

The classification of metal silicon is usually classified according to the content of three main impurities of iron, aluminum and calcium contained in the metal silicon component. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.

Product Usage

1、silicone rubber, silicone resin, silicone oil and other silicone production.

Silicone rubber has good elasticity and high temperature resistance, used in the manufacture of medical supplies, high temperature gaskets and so on.

Silicone resin is used to produce insulating varnish, high temperature coatings and so on.

Silicone oil is an oil whose viscosity is very little affected by temperature. Used in the production of lubricants, varnish, fluid spring, dielectric fluid, etc..

2、 high-purity semiconductor manufacturing

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

3、Manufacture of alloys

Aluminium alloy is the industry with the largest amount of silicon metal. Silicon aluminium alloy has low density, small coefficient of thermal expansion, good casting performance and wear resistance. With its casting alloy castings with high impact resistance and good high-pressure densification, can greatly improve the service life. Commonly used in the production of aerospace industry and automotive industry and other parts. Silicon-copper alloy welding performance is good, by the impact is not easy to produce sparks. It is explosion-proof and can be used to make storage tanks. Silicon aluminium alloy is a strong compound deoxidiser. It can replace pure aluminium in the steelmaking process, improve the utilization rate of the deoxidant, purify the steel and improve the quality of steel.
