RudCo supplies high-purity magnesium pieces commonly used in foundry operations that require precise additions of magnesium, particularly in the production of ductile iron through plunging and converter processes. Magnesium pieces help foundries achieve tight control over alloy chemistry while minimizing magnesium losses during melt. Magnesium is also well-suited for direct alloying applications, where accurate dosing of pure magnesium is critical to meeting final specifications.
