PDF Print

High-quality soldering work is done in our own clean high-vacuum furnace. FMB can also offer the right quality when soldering different materials and combinations of high-grade steel, copper, Glidcop or ceramic.

We are able to offer the following technologies and services :

° UHV–proof brazing on components made of copper,Glidcop, stainless steels, molybdenum, tungsten, mu–metal, ceramics
° Brazing under partial pressure (Ar and N2)
° Stress relief annealing
° Annealing for reduction of residual permeability
