Annealing & Brazing in High Vacuum

Molybdenum high-performance-material hot zone (operating temperature 1400 C)

High-vacuum annealing and brazing imposes exacting demands on the purity and cleanliness of the furnace, on temperature uniformity and on the capability to achieve rapid-cooling.


Depending on the operating conditions and the products to be processed, metallic hot zones and charge carriers made of molybdenum and tungsten are used.
  • Vacuum brazing for applications in aerospace  (brazing repair of turbine blades, brazing of honeycombs)
  • Outgassing and clean annealing in electronics and medical technology
  • Production of vacuum switches for power engineering
  • Laboratory, production and special furnaces in development departments and in materials research
