Aluminium Alloys

Aluminum Alloys industry is an important part of non-ferrous cast metal industry. Aluminum alloys encompass a combination of aluminum metal and other alloying elements. It supports maintaining the precise chemical specifications in the finished products.
Aluminium foundry alloys are used for aluminium castings.

Gravita’s production is based on Secondary aluminium. Consistent high metal quality is ensured using top-grade raw materials and applying best practices. Our foundry alloys are produced to meet individual customer specifications in the main alloy groups meeting specifications in accordance with BS and JIS standards.
