Magnesium‑Calcium (Mg‑Ca) Master Alloy | Eco‑Friendly Grain‑Refiner for Magnesium

Magnesium‑Calcium (Mg‑Ca) Master Alloy | Eco‑Friendly Grain‑Refiner for Magnesium

Vacuum‑smelted Mg‑Ca master alloy. Calcium‑magnesium modifier for grain refinement, flame‑retardant performance and corrosion‑resistance improvement. Custom calcium grades supported.

Our Magnesium‑Calcium master alloy is vacuum‑melted inside our Ganzhou workshop. This rare‑earth‑free intermediate alloy is widely applied as grain‑refining and flame‑retardant additive for magnesium melt. Homogeneous calcium distribution greatly optimizes casting safety, reduces burning loss and improves microstructure uniformity of finished magnesium castings.

Standard industrial grades and custom calcium‑content products are available, with rigorous impurity control for automotive, die‑casting and biodegradable magnesium material projects.

Chemical Composition:

Grade	Ca Content	Magnesium (Mg)	Max Impurities (Fe, Si, Cu, Ni, Al, Mn)
Standard Mg-Ca	Customizable 10%–30%	Balance	≤0.05% total

Custom calcium proportion and special specifications are available on request.
