  • Flux coated brazing sheet
    Patent number: 7337941
    Abstract: A brazing flux mixture comprised of brazing flux, a polyvinyl butyral resin binder, and an organic solvent which can be applied over an entire aluminum alloy brazing sheet, or can be applied on the brazing sheet only where metallurgical bonds or joints are required, that is sufficiently durable to withstand processing operations and also provides good metallurgical bonds upon brazing.
    Type: Grant
    Filed: April 21, 2003
    Date of Patent: March 4, 2008
    Assignee: Alcoa Inc.
    Inventors: Deborah B. Scott, legal representative, Raymond J. Kilmer, Joseph R. Dougherty, Robert P. Anthony, Darwin H. Scott

  • Corrosion resistant aluminum material
    Patent number: 4828794
    Abstract: An aluminum core alloy for use in the manufacture of brazed heat exchanger assemblies having high resistance to corrosion and moderate strength. A preferred composition of the aluminum base alloy consists of from 0.13 to 0.22% titanium, from 0.8 to 1.5% manganese, 0.4 to 0.6% copper, up to 0.7% iron, up to 0.3% silicon, up to 0.3% magnesium, with the balance being essentially aluminum and normal impurities. Another preferred composition, which is a modification of the preceding composition, includes 0.3 to 0.6% magnesium.
    Type: Grant
    Filed: March 6, 1987
    Date of Patent: May 9, 1989
    Assignee: Reynolds Metals Company

  • Aluminum battery alloys
    Patent number: 4554131
    Abstract: Aluminum alloys suitable for use as anode structures in electrochemical cs are disclosed. These alloys include iron levels higher than previously felt possible, due to the presence of controlled amounts of manganese, with possible additions of magnesium and controlled amounts of gallium.
