Product Description

4343/3003/4343 cladded aluminum coil/Strip for fins of condensers

 

Cladded aluminum strip sheet comprises of a core alloy clad on 1 or 2 sides with a lower melting aluminum-silicon (Al-Si) alloy. This thin layer, usually makes up 5 % to 15 % of the total thickness of the brazing sheet.

 

It melts and flows during the brazing process, to provide upon cooling a metallic bond between the components. It is common that the braze clad alloy are from the AA 4xxx series or more particularly AA 4343 (Al-6.8~8.2 wt.% Si).
