Unalloyed Grey Cast Irons

Ductile Irons Spheroidal Graphite (SG) Irons

Austenitic Irons (Ni-Resist)

High Chrominium Irons For Wear and Heat resistance

Aluminium Alloys

We produce castings in grey cast iron, ductile iron(also known as nodular or SG), austenitic iron, high chromium irons for heat or wear resistance and aluiminium alloys.

Listed on this page are typical examples of the metal specifications that we can produce castings to. This is not an exhaustive list as we can produce castings to international specifications or to individual customer's requirements.

 

We regularly produce castings to individual customers metal specifications and to international specifications.

Please contact us with your requirements.
