  • Brazed aluminum structure and method for forming same
    Publication number: 20070000969
    Abstract: A brazed aluminum alloy structure is formed that includes a first component formed of an aluminum alloy sheet, a second metal sheet component formed of an aluminum alloy and a braze fillet metallurgically bonding a faying surface of the first component to a faying surface of the second component. The braze fillet is composed of a hypoeutectic aluminum silicon alloy comprising between 0.005 and 0.045 weight percent strontium. The strontium addition produces a microstructure characterized by coral-like silicon particles that improve corrosion resistance.
