ALLOYS FOR TOOLS AND HARD METALS

The combination of hard metals and steel supports and the high performance
demanded by the tool industry drive us to keep looking for new solutions.

The development of multi-layer tri-metal brazing materials and their ensuing
evolution make work processes that much easier,
while also ensuring tools have a longer service life.

TRI-METAL BRAZING ALLOYS FOR HARD METAL AND TOOL BRAZING

2 Leghe per utensili2

Tri-metal brazing alloys were developed to absorb the metals’ internal stress, which forms during cooling following the brazing process.
Said stress occurs due to the various metals having different thermal expansion coefficients.
The tri-metal alloys’ plastic deformation effectively cancels out this stress.
