Vacuum Furnace added to Alfreton division

July 2, 2020


Curtiss -Wright Surface technologies are pleased to announce the addition of in-house Vacuum Brazing, Sintering and Heat treatment within our Component Coating and Repair facility based in Alfreton Derbyshire UK.


The new Vacuum Furnace has a working area of 600mm x 450mmx 900mm and is fitted with a sealed cooling system meeting the latest environmental legislation.

The vacuum brazing process uses a filler alloy which is pre-placed on the component in a location that as the furnace temperature is raised and the filler metal alloy melts, it flows into the assembly capillary joints and affects a strong bond.


The Vacuum Furnace also brings Sintering and Heat Treatment capabilities to Curtiss-Wright Surface technologies for components such as:

  • Stators
  • Nozzles
  • Honey Comb Seals
  • Rings
  • Blades
