Magnesium powder (0–2 mm) is a highly reactive, silvery-gray metal used in pyrotechnics, fireworks, and as a reducing agent in chemical synthesis. Its rapid combustion makes it essential for flare compositions and metallurgical applications. This product has a CAS number of 7439-95-4, a molecular weight of 24.3 g/mol, and requires ambient storage with strict handling due to its flammability. The signal word is *Danger*, indicating severe hazards if improperly managed. Molekula supplies Magnesium Powder 0–2 mm from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
