Clading Aluminum Strip Sheet

Current Position :HOME/Brazing Sheet/Clading Aluminum Strip Sheet

Cladding aluminum strip sheet
 
Cladding 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).
 
However, if larger fillets are desirable, or if in a situation where brazing is likely to occur at lower temperatures, AA4045,AA4047 is the preferred choice.
