Which grades are industrial silicon metal powder

Many people know a little about metallic silicon powder, especially girls. As we all know,silicon metal powder has industrial metal silicon powder and chemical metal silicon powder . Then, among the common metal silicon powder grades, which are industrial metal silicon powder .

What is industrial silicon metal powder ?

Industrial metal silicon powder generally refers to a grade containing more than or equal to 98.5% silicon. Also known as metallurgical metal silicon powder . Metallurgical grade metal silicon powder is mainly used in the production of silicon aluminum alloy, which is widely used in the production of aluminum products. Compared to chemical grade metal silicon powder , the purity is relatively low.

Which grades belong to industrial silicon metal powder ?

These grades 553, 441, 331, and 2202 are industrial metal silicon powder . The general grade is named after the three impurity contents of iron, aluminum and calcium.

For example, 553 represents that the industrial silicon contains less than or equal to 0.5% iron, aluminum content is less than or equal to 0.5%, and calcium content is less than or equal to 0.3%. For customary reasons, 2202 is also abbreviated as 220 to represent calcium less than or equal to 0.02%. The industrial silicon powder at the beginning of 2 is generally called chemical silicon powder .
