Our Brazing Tradition

Over 100 years ago in 1906, Mr. Wasserman started his business with the development, production and sales of brazing fluxes. In the following years, Castolin was formed and began to develop new low temperature and eutectic brazing alloys. Castolin was not only revolutionary in terms of its developments, in patents and in manufacturing processes, but also in training salesmen and customers on the brazing and soldering methods. Castolin Eutectic has always been years ahead of the competition. For example, Castolin developed the first non-corrosive aluminium fluxes in the 60s, the first

aluminium pastes in the 70s and the first nickel pastes in the late 70s. These products were 15 to 20 years before their time.

Castolin Eutectic has patented over 200 products in its history and is still developing and improving products and processes for its customers today.

Castolin Eutectic, with its 100 years tradition of developing and innovating soldering and brazing solutions, is the right partner for you.

At Castolin Eutectic, we understand that each application has individual and specific requirements. Therefore we have designed and manufactured several types of coated rods to meet the demands of our customers.

Unlike most competitors, Castolin Eutectic does not use a universal flux for all rods, each rod contains the type of flux required by the alloy being coated.

The Coating Names

Each alloy has a name, like for example 1020. Behind the name of the alloy, there are letters which specify the type of flux coating: 1020 F is a 1020 alloy with an F coating. The product name and coating type along with the batch number is printed on each rod. Additionally, each alloy has a specific flux coating colour which helps operators to know which
