Product Description

3003 Aluminum Strip for Air Cooling Fin Material

Aluminium brazing material production

Complex assemblies can be turned into single unit by just one pass through a brazing furnace. Aluminium brazing facilitates the joining of parts with a near-eutectic Ai-Si filler alloy, the liquid temperature which is about 50 º C lower than that of the core. In serial heat exchanger production the filler alloy is supplied via a thin clad on a core alloy.


Cladding thickness

Signi's well established, roll bonding process guarantees tight cladding thickness tolerances, which are essential for ensuring stable brazing results. Rather thin clad layers of 5% can be manufactured, as well as brazing materials also with a cladding thickness of 20%.
