Product details

Alloys are produced as continuous cast or mold cast ingots. The products are stacked and strapped into bundles of various sizes. Depending on the particular production source, our foundry alloy ingots are supplied in weights of 7-22 kg, and bundle weights can range from 700-1200 kg.

Frequently used alloy groups:

  • AlSi7Mg – alloys
  • AlSi9Mg – alloys
  • AlSi11(Mg) alloys
  • AlSi10MgMn alloys
  • AlSi5-9MgCu alloys

Other alloys that can be supplied are;

  • AlMg3 alloys
  • Al 99.5E, 99.7E (rotor alloys)
