Mg

Primary magnesium ingot at Mg ≥ 99.9% is a high-purity reductant and alloying metal. Its strong affinity for oxygen and sulphur drives the core mechanisms: in hot-metal desulphurization, injected Mg reacts to form stable MgS that floats into slag, cutting S toward ≤ 0.005% for clean-steel and pipeline grades. In ductile-iron production it is the active element behind nodulizer (FeSiMg) chemistry, converting flake graphite to spheroidal form. In aluminum alloys it is the primary strengthening element of the 5xxx series and pairs with Si as Mg2Si in 6xxx, and it sets strength in many die-cast grades. Typical additions run roughly 0.1-0.5% Mg in cast-iron treatment and up to several wt% in Al alloys, with melt loss compensated per practice. The tight residual ceiling — Al ≤ 0.02%, Si ≤ 0.01%, Fe ≤ 0.005%, Cu ≤ 0.005%, Ni ≤ 0.001% — keeps recovery predictable and protects downstream alloy targets; the same purity suits titanium-sponge (Kroll) reduction. Supplied as 7.5 / 12 kg ingot with COA and MTC, multi-regional sourcing, CIF Marmara or Gebze bonded stock, 20 MT FCL. Send your grade and tonnage for an RFQ.
