Primary magnesium ingots — 99.90% to 99.98% Mg.
Produced on our own reduction lines and supplied to Mg9990, Mg9995 and Mg9998 grades against GB/T 3499 and ASTM B92.
Pure Magnesium Ingots
Primary magnesium ingot is the base feedstock for aluminum alloying, steel and iron desulphurisation, titanium sponge reduction and magnesium alloy production.
CHM operates its own primary magnesium capacity, so ingot supply is not dependent on the spot market — a material advantage for customers running annual contracts.
Standard grades are Mg9990, Mg9995 and Mg9998, cast as 7.5 kg ingots and bundled for direct charging.
What this material delivers in production.
Own primary capacity
60,000 t/year reduction capacity supports contract volumes and stable pricing.
Three standard grades
Mg9990, Mg9995 and Mg9998 to GB/T 3499 and ASTM B92 chemistry.
Low iron and nickel
Controlled Fe and Ni for corrosion-critical downstream alloys.
Clean surface condition
Ingots are skimmed and inspected; no flux residue or heavy oxide.
Traceable heats
Lot marking and mill certificates on every bundle.
Contract supply
Scheduled monthly release with North American warehousing.
