Master Alloys

Calcium-Aluminum master alloy (Ca-Al).

A stable calcium carrier for lead-calcium battery grid alloys, secondary steelmaking and aluminum melt treatment.

Product introduction

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.

Product features

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.
