TOP TEC RANGE - Alloys compatible with the ROHS standard

TOP TEC alloys have a melting range below 750°C.

These alloys are used for their high electrical conductivity, their absence of toxicity in the food industry, their ductility in processing copper and its alloys on solid pieces.

These alloys are suitable for all steels, copper and copper alloys and for nickel alloys.

Economic alloy but with low silver content; recommended for large series brazing, provided the heating method is particularly fast.

Alloy with a wider melting range (670-740 °) offers excellent fluidity but reduced capillarity. Use is recommended if joints are important.

This alloy is suitable for all jobs that require quick brazing. Alloy suitable for the assembly of copper and steel gas pipes.

All-purpose alloy that offers great fluidity and excellent capillarity. Used for assembling copper and steel gas pipes.

Alloy widely used due to its low melting point, its good fluidity and its very low melting range (630-655 °). Alloy for silver, copper, white colour.
