Calcium-Aluminum master alloy (Ca-Al).
A stable calcium carrier for lead-calcium battery grid alloys, secondary steelmaking and aluminum melt treatment.
Calcium-Aluminum Alloy
Calcium-aluminum master alloy is the standard route for introducing calcium into lead, aluminum and steel melts where pure calcium is impractical to handle.
CHM supplies Ca-Al in calcium contents from 10% to 75%, cast as ingot, waffle plate or briquette with tightly controlled iron and silicon levels.
The alloy is widely used in maintenance-free lead-calcium battery grids, in ladle metallurgy for inclusion modification, and in aluminum casting alloys for structure control.
What this material delivers in production.
Consistent Ca content
Every heat spectrometer-verified; composition held within a narrow band lot to lot.
Low impurity levels
Controlled Fe, Si, Mg and Na for battery-grade and steel-grade applications.
Fast dissolution
Alloy form dissolves quickly and predictably, reducing melt hold time.
Stable in storage
Does not require inert-gas storage under normal warehouse conditions.
Multiple cast forms
Ingot, waffle plate and briquette sized for automatic and manual charging.
Bulk supply
Container-scale supply with scheduled release to North American consignment stock.
