Brazing – joining innovations

Pastes and filler metals

Complete solutions for your brazing needs

Höganäs offers a full range of nickel based and stainless BrazeLet® filler metals for high temperature brazing. Typically our brazing alloys are used to join stainless steel components like exhaust gas recirculation coolers (EGR), boilers, metal catalytic converters, waste heat recovery (WHR), heavy-duty oil coolers, brazed-plate-heat exchangers (BPH) or components for coffee machines.

Definition of Brazing

Brazing is a thermal process for securely joining materials. The parts are heated up to the working temperature of the brazing alloy which flows into the gap by capillary action. One big advantage of brazing is that virtually any metallic materials can be combined. A prerequisite for brazing is the spreading of the molten alloy (wetting) on the base material.

Why Brazing?

One example where brazing is superior to other techniques is for manufacturing heat exchangers resistant to corrosion and high temperatures. The core component designs often does not allow the parts to be joined by welding. Even if it is possible, welding is a serial process where production time is proportional to total joint length, whereas brazing of hundreds of heat exchangers can be done in one batch simultaneously.

Why Höganäs brazing?

Höganäs offer stainless steel filler metals for reliable braze joints fulfilling customers demand in properties, lifetime and quality of their components. As the global leader in metal powders, Höganäs has in-depth knowledge about high-temperature brazing filler metals and how to fine-tune their properties. Development of new filler metals by R&D benefit by pilot center for atomizing small batches of powder, metallographic and analytic labs and our PoP centre for testing applications, all located in Höganäs Headquarter, Sweden.

For application of the brazing filler metal the powder is offered as unique pastes. Höganäs brazing pastes have fine-tuned properties shaped for reliable and sustainable selective application methods like dispensing, roller coating or screen printing. The Höganäs Brazing filler metal powder and paste production is located in Ath, Belgium. Production is certified according ISO9001, ISO14001 and IATF16949 following automotive standards.
