Frequently Asked Questions

What is aluminothermal calcium?

Aluminothermal calcium is produced by reducing calcium oxide with aluminum at high temperatures. It is further refined to achieve high purity (≥99.0%) for industrial use.

What are the main applications of calcium metal?

Calcium metal is primarily used in the steel industry for deoxidation, desulfurization, and inclusion modification. It is also used in aluminum alloys, chemical synthesis, and as a getter in vacuum tubes.

How is Mg-Ca alloy used in foundries?

Mg-Ca alloy (70/30) is used to nodularize cast iron, improving ductility and strength. It also acts as a modifier in aluminum-silicon alloys.

Is your packaging safe for international shipping?

Yes. We comply with all UN and EU regulations for reactive metals. Products are vacuum-sealed in steel drums or moisture-proof bags for safe transport.

Do you provide test reports?

Yes. SGS test reports are available for Mg-Ca alloys. ISO-certified quality documentation is provided with every shipment.
