VIM Alloys
For Aerospace and other critical applications
We take pride in satisfying individual and OEM global requirements from our specialist alloy manufacturing facilities which include Vacuum Induction Melting (VIM), alongside Vacuum Arc Remelting (VAR) and Electro-Slag Remelting (ESR).
These facilities are coupled to our unique integrated mill, machined part and service centre offering, which allows us to deliver around the world as ingot, bar, cut piece or machined part.
All our specialist alloy products are manufactured in the UK and are used in the production of engine components, landing gear, controls, aero structure and helicopter powertrain components.
