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.

1) The data on the silver content of sandwich brazing alloys refer only to the brazing layer.
