What is Magnesium?

Magnesium (CAS 7439-95-4) is a lightweight structural metal and reactive reducing agent used in manufacturing, metallurgy, and agriculture.

Where is Magnesium used?

  • Automotive and aerospace: lightweight structural components that improve fuel efficiency and load capacity
  • Steel and aluminum production: desulfurization and deoxidation agent that improves metal purity at the refinery stage
  • Agriculture: soil amendment and fertilizer input that corrects magnesium deficiency in crops
  • Pharmaceutical and food manufacturing: precursor for magnesium salts such as magnesium oxide, carbonate, and stearate used in tablets, supplements, and food fortification
  • It also serves as a functional raw material and processing agent in industrial operations.

Commercial specifications

  • Purity levels typically range from 99.0% to 99.9%+.
  • Packaging is generally offered in drums or bulk quantities depending on the physical form and end-use specification.
  • Compliance with FCC, USP, and Ph. Eur. standards where applicable.
  • Supply chain supports BP, EP, and ACS quality standards.
