Aluminum Brazing Sheet DC Cast Sheet Technical Data White 91 SPECIFICATIONS Alcoa Products for Brazed Applications Alcoa produces the entire spectrum of 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 (VB) applications and for controlled atmosphere brazing (CAB) applications using potassium aluminum fluoride fluxes. Alcoa brazing materials are available in O-, H1x-, and H2x-tempers, in thicknesses from 0.05 mm to 4.1 mm, and clad on one or two sides, with nominal cladding ratios from 4 to 20 percent of total material thickness on each clad surface.* PRODUCT AVAILABILITY AMP 0035† AMP 0330† AMP 0333† AMP 0336† AMP 0390 AMP 0359† AA 3003 AA 3005 AA 3105 Si 0.25 0.30 0.25 0.25 0.6 0.20 0.6 0.6 0.6 Fe Cu Mn Mg Zn Ti 0.6 0.20-0.40 0.50-1.0 0.30-0.6 0.05 0.25 0.50PRODUCT 0.30-0.7 1.0-1.3 0.40-0.60 0.10 0.10-0.25 AVAILABILITY 0.6 0.20-0.40 0.8-1.3 0.10 0.05 0.25 0.40 0.40-0.6 1.0-1.3 0.10 0.10 0.10-0.20 0.7 0.05-0.20 1.0-1.5 1.3-1.7 0.35 0.40-0.6 1.0-1.3 0.20-0.30 0.05 0.10-0.25 0.7 0.05-0.20 1.0-1.5 0.10 0.7 0.30 1.0-1.5 0.20-0.6 0.25 0.10 0.7 0.30 0.30-0.8 0.20-0.8 0.40 0.10 Other 0.25 Zr 0.25 Zr 0.10 Cr 0.20 Cr AMP = Alcoa Mill Products proprietary alloys.
