Brazing Foils

VITROBRAZE® - Amorphous brazing filler material

Amorphous VITROBRAZE® foils are used as 100% metallic filler materials in brazing processes. The different Qualities of VITROBRAZE are optimized for joining of steel and stainless steel, nickel and cobalt alloys, or copper and brass alloys, among others. VITROBRAZE products are available as strip material and can be customized in geometry.

Benefits

  • 100 % metallic, ductile, flexible
  • Foils and preforms are simple to use in automated production
  • Create uniform, strong and leak free joints with an outstanding quality
  • The use of foils and preforms reduces waste and enhances manufacturing efficiency
  • EGR Coolers
  • Metallic Catalytic Converters
  • Heat Recovery Systems
  • Diesel Particulate Filters
  • Fuel Cells
  • IGBT Coolers
  • Brazed Plate Heat Exchangers (BPHE), including drinking water applications
  • CuproBraze® Heat Exchangers

VITROBRAZE brazing foils are used in industrial, aerospace and automotive applications.

Nickel brazing foils are used for applications where resistance against corrosion, oxidation and heat are required.

VITROBRAZE nickel and iron based products are available as strip with a width from 2.5 mm to 200 mm and a thickness from 20 μm up to 50 μm.  They have no limitation in shelf life.

Comparison of the corrision resistance of brazed VITROBRAZE / AISI 316 L joints towards exhaused gas condensate versus brazing temperature.

 

By considering the 5000 years of brazing history, the nickel based filler metals are a very young group of materials. The first Nickel-BFM (Brazing Filler Metal) was developed for joining parts of jet engines in 1947. This new group of BFMs and the according brazing procedures were therefore continuously improved in the following decades. Modern alloys of this BFM group are mainly optimized for corrosion resistance and joint strength.

Our amorphous VITROBRAZE filler metal foils are produced by the Rapid Solidification Technology which is also used for our soft magnetic VITROVAC® and VITROPERM® products. The production of amorphous metals requires a manufacturing technology that operates on the basis of the extremely fast cooling rates, which is known as rapid solidification. Amorphous structures are characterized by the absence of a crystal lattice or a long range order. With this random, spatially uniform arrangement of the constituent atoms, their structure is similar to that of liquids.

The nature of this  production process is the reason why amorphous alloys are offered in the form of thin,  ductile metal foils. Subsequently, tapes, parts and preforms can be made by e.g. slitting, cutting, stamping and etching.
