DC Cast Sheet
Alcoa Products for Brazed Applications
Alcoa produces the entire spectrum of sheet components for nearly every brazed aluminum heat exchanger
or assembly – from light-gauge fin stock, to heater core and radiator tubes, to heavy-gauge headers and
reinforcements. Alcoa alloys are used for vacuum brazing applications and for controlled atmosphere
brazing applications utilizing potassium aluminofluorate fluxes. Alcoa brazing materials are available in O-,
H1x-, and H2x- tempers, in thicknesses from 0.08 mm to 3.5 mm or more, and clad on one or two sides with
common nominal cladding ratios from 5 to 20 percent of total material thickness on each clad surface.*
