Cladding aluminum strip sheet

Brazing is a metal joining process utilizing a filler metal that melts above 840ºF and below the melting point of the base metals. The filler metal is drawn into the joint by  capillary attraction producing a sound, leak-proof connection.

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, AA‑4045,AA4047 is the preferred choice.
