Magnesium turnings are highly reactive metallic flakes primarily used in pyrotechnics, alloy production, and as a reducing agent in chemical synthesis. They ignite easily in air, producing intense white flames, and are essential for applications requiring strong exothermic reactions. Magnesium turnings (CAS 7439-95-4) have a molecular weight of 24.31 g/mol and are stored at ambient conditions. They carry a **Danger** signal word due to their high flammability and reactivity. Molekula supplies magnesium turnings from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
