BrazeTec - the partner in brazing technology

BrazeTec - the partner in brazing technology

BrazeTec offers you a great range of brazing alloys in several delivery forms. Suitable for your application Umicore produce alloys in wire, rods, strips, preforms and brazing pastes.

BrazeTec Silver Brazing Alloys can be used with any type of steel, copper and copper alloy, also nickel and nickel alloy. They are generally capable of being used for operating temperatures from minus 200 to plus 200 degrees.

BrazeTec Active Brazing Alloys for the Brazing of Ceramic Materials

BrazeTec Active Brazing Alloys for the Brazing of Ceramic Materials

BrazeTec active brazing alloys are developed to suit the special characteristics of joining ceramics and metals. For this purpose the minimal brazing temperature is 850 °C  whereas higher brazing temperatures can improve the wetting behaviour.

Pure Argon (4.8) or vacuum (<10-3mbar) is used as the protective brazing atmosphere.

The temperature for a vacuum brazing should range between 900 °C to 1,000 °C to avoid the evaporation of silver.

BrazeTec active brazing alloys are available as strip, wire, preform as well as paste, which can be adapted accoring to customer requirements.

BrazeTec Brazing Alloys for Copper and Copper Based Materials

BrazeTec Brazing Alloys for Copper and Copper Based Materials

BrazeTec Silfos brazing alloys were especially developed for the joining of copper with copper or of copper alloys (brass, bronze, red brass) at brazing temperatures between 650 °C and 760 °C. Once joined they are suitable for operating temperatures ranging from –70 °C to +150 °C.

These brazing alloys are not suitable for joining steels (Fe) and nickel alloys due to brittle-phase-generation nor should be applied within sulphur containing ambience.

The use of an additional flux is not necessary when brazing copper to copper due to its phosphorous-content but should be used with copper alloys.

BrazeTec Brazing Pastes

BrazeTec Brazing Pastes

For innovative connection possibilities, BrazeTec also offers brazing materials as pastes, in addition to the solid forms. A brazing paste is a homogenous, ready to use, mixture of metallic brazing powder, flux and solvents. Polymers and other additives prevent the settlement of the brazing powder and determine the application and flow characteristics of the brazing paste.

 The applications can be done by the following processes:

  • dispensing
  • screen-printing
  • roller-coating
  • spraying

 Available as brazing paste are

  • silver based brazing alloy,
  • nickel based brazing alloys,
  • copper based brazing alloys (CuproBraze) and
  • active brazing pastes.

BrazeTec Brazing Fluxes

BrazeTec Brazing Fluxes

BrazeTec fluxes are used in the brazing process for removing the oxide layer. The choice of flux is made in accordance with the working temperature of the brazing alloy and the base materials.

 Please contact us and we are pleased to help you with the right choice.

BrazeTec Alloys and Sandwich Alloys for the Brazing of Tungsten Carbides

BrazeTec Alloys and Sandwich Alloys for the Brazing of Tungsten Carbides

For the brazing of tungsten carbides and materials such as wolfram, molybdenum, tantalum, and chrome that are hard to wet,  BrazeTec offers specially developed alloys and sandwich alloys.

 The advantage of sandwich alloys is that they can compensate for internal stresses caused by the different thermal expansion coefficients during cooling.

BrazeTec CoMet – Brazing Rods, Cadmium Free & Flux Coated

BrazeTec CoMet – Brazing Rods, Cadmium Free & Flux Coated

BrazeTec offers several cadmium free brazing alloys from its comprehensive range of products under the name of CoMet (coated metal) as flux coated rods. The flux is equivalent to the type FH 10 in accordance with DIN EN 1045 and is boraric acid free.

 Please contact us for getting more information of the alloys in particular.

BrazeTec BlueBraze - Silver reduced Brazing Alloy

BrazeTec BlueBraze - Silver reduced Brazing Alloy

Less silver: up to ten percent less in weight!

By substantially reducing the silver content in our new BrazeTec BlueBraze brazing alloys, you achieve permanent cost reduction. You become less dependent on silver price fluctuations in the market of precious metals and thus get more planning stability when calculating the cost of your materials.

Same processing properties:

Construction, processes and processing remain unchanged.

During the development of BrazeTec BlueBraze, apart from reducing silver content, the top priority was retaining the important properties of materials of standard brazing alloys.

The functionality of BrazeTec BlueBraze has been confirmed in extensive tests and experiments. For you as customer, this means that neither constructions nor processes must be changed.

More brazing alloy: About six percent brazing material per kilogram.

Silver is very dense, like gold. For this reason, thanks to the lower proportion of silver in BrazeTec BlueBraze, the density of our new brazing alloys is lower too.

The result: You can obtain up to four meters*) more brazing material per kilogram. Therefore, in the future you will be able to carry out about six percent more brazing joints with the same quantity of material or, conversely, save on the cost of materials – permanently!

In case of a specific application, we will gladly assist you and will also be ready to support and advise you at our Brazing Center.

Further alloys are at the ready. Please visit www.BlueBraze.com to find out more about our latest products.

 

Company profile

Umicore - BrazeTec
Your Partner in Brazing Technology
Umicore´s Business Line, BrazeTec, which was formed from Degussa Löttechnik, is a leading manufacturer of high-quality brazing alloys and solders, brazing alloy and solder pastes and fluxes.

BrazeTec materials are used to manufacture a wide range of products, from simple everyday objects to high-grade tools and bulk industrial products. Examples include spectical frames, cooking pans, hard metal tipped circular saw blades, mills, radiators and air conditioning equipment. Its products are also used in installation engineering (gas, heating and water).

BrazeTec produces and sells these products through a global sales and logistics organisation and has production facilities in Hanau (Germany), Vicenza (Italy),  Glens Falls (USA), São Paulo and Manaus (Brazil). 

Using its many years of experience and expert knowledge of brazing and soldering processes in specific sectors of industry, BrazeTec's own Brazing Center develops solutions customised to the requirements of individual clients and develops techniques for bonding metallic materials, hard metals and ceramics.

We continuously improve our alloys both in terms of performance and cost efficiency. For example you should test our silver reduced brazing alloy "BrazeTec BlueBraze"! With BrazeTec BlueBraze we accomplished it to reduce the silver content of the conventional brazing alloys by up to 20 % while maintaining its brazing characteristics.
