    摘要: An aluminum brazing alloy composite sheet is provided which can be utilized in both the vacuum brazing process and the controlled atmosphere brazing process for the brazing of aluminum parts. The brazing alloy composite sheet consists of an aluminum core alloy of the 3XXX, 5XXX or 6XXX type clad at least on one major surface with a lithium-containing aluminum filler alloy containing from about 0.01% to about 0.30% by weight lithium. The core alloy may contain up to about 2% by weight magnesium and is suitable for producing aluminum alloy heat exchanger assemblies, such as radiators or evaporators.

    摘要: A process for improving the fillet-forming capability of brazeable aluminum articles includes providing a brazeable aluminum article, having at least one surface; and contacting the surface with a dilute, aqueous solution of fluoridic compounds, for at least 5 seconds at a temperature ranging from about 150.degree. to 212.degree. F. to produce an oxide-free surface which can be readily brazed with a minimal drip loss.

    摘要: Minor additions of calcium (Ca) to Al--(1% to 14%) Si filler metals result in larger fillets than conventional Al--Si alloys normally used in the NOCOLOK brazing process. This new filler metal can be clad to 2XXX, 3XXX, 6XXX, and 7XXX series alloys and brazed with a fluoride flux. The filler metal contains between 0.005% Ca to 0.3% Ca. The new filler metal could have up to 0.3% Mg and up to 0.3% Li. Additionally, the brazing process can optionally include an aqueous treatment with a fluoride salt to reduce the need for NOCOLOK fluxing.
