BRAZING
Facilities are available for brazing components, in vacuum, or reducing atmosphere, up to 250mm diameter × 300mm long. The braze material normally employed will be Silver/Copper eutectic. This preferred material produces a high seal strength at low cost. For applications where higher operating temperatures or other design constraints are involved, Gold/Copper, Gold/Nickel or Copper braze materials are employed, the latter braze material having a liquidus point of approximately 1100°C.
