摘要： This application discloses a corrosion-resistant brazing sheet package for use in manufacturing tubing. The brazing sheet package includes a core layer of aluminum-containing alloy comprising from 0.1 wt % to 0.2 wt % of titanium. The core layer has a first side and a second side. The first side of the core layer is adjacent to a first cladding layer to form a first interface. The second side of the core layer is adjacent to a second cladding layer to form a second interface. The first cladding layer and the second cladding layer each include from 2.5 wt % to 4.0 wt % of zinc.

摘要： An aluminum alloy fin stock material comprising about 0.9-1.2 wt. % Si, 0.3-0.5 wt. % Fe, 0.20-0.40 wt. % Cu, 1.0-1.5 wt. % Mn, 0-0.1% Mg and 0.0-3.0% Zn, with remainder Al and impurities at ≤0.15 wt. %. The aluminum alloy fin stock material is produced in a form of a sheet by a process comprising the steps of direct chill casting an ingot, hot rolling the ingot after the direct chill casting, cold rolling the aluminum alloy to an intermediate thickness, inter-annealing the aluminum alloy cold rolled to an intermediate thickness at a temperature between 200 and 400° C., and cold rolling the material after inter-annealing to achieve % cold work (% CW) of 20 to 40%. The aluminum alloy fin stock material possesses an improved combination of one or more of pre- and/or post-brazes strength, conductivity, sag resistance and corrosion potential. It is useful for fabrication of heat exchanger fins.
