Calcium / Aluminum Master Alloy

Advanced master alloy engineered for lead grid alloying in modern maintenance-free lead-acid batteries, providing rapid dissolution, minimal oxidation loss, and superior casting homogeneity.

Calcium / Aluminum Master Alloy (Ca-Al)

Lead-calcium (Pb-Ca) grid alloys enhance grid mechanical strength, minimize electrolyte electrolysis (water loss), and improve corrosion resistance.

Due to the reactive nature of pure calcium and the challenges of direct alloying, Ca-Al master alloys provide a highly efficient, protected mechanism to introduce calcium and aluminum simultaneously into molten lead baths with minimal dross.
