Silicon Metal 553 | Si≥98.5%, Lumps, Grain, Powder


How to Name Silicon Metal 553?

The numbering principle of silicon metal 553 is: the first and second represent the percentage content of iron and aluminum, and the third (and fourth) represents the content of calcium. So, silicon metal 553 means that the iron element is greater than 0.5%, the aluminum element is greater than 0.5%, the calcium element is less than 0.3%, and the silicon content is not less than 98.7%.

Specific Application of Silicon Metal 553

  • It is used as a reducing agent when smelting aluminum alloy.
  • The high temperature fluidity of alloy can be improved when smelting alloy. Reduce shrinkage; Reduce the tendency of hot cracking; Improve wear resistance. The alloy castings cast with it have high impact resistance and good high-pressure densification, which can greatly improve the service life, and are often used in the production of auto parts and aerospace fields.
  • Adding silicon metal in steelmaking, it can play the role of deoxidizer.
