    摘要： An improved aluminum alloy, referred to as a core material, is provided which is particularly adapted for use in manufacturing articles by vacuum brazing techniques because such core material has optimum resistance to sag at brazing temperatures and because it has a solidus of about 1160*F to 1180*F, is heat treatable to a minimum yield strength of 12,000 psi, and is corrosion resistant. A heat treatable cladding alloy is also provided for use as a brazing component either alone or with such core material and other suitable core materials. The preferred cladding alloy has a liquidus of about 1,065*-1,085*F, has a narrow melting range of about 20* to about 40*F, is corrosion resistant, and provides joints of optimum strength and quality.

    摘要翻译： 提供了一种改进的铝合金，被称为芯材，其特别适用于通过真空钎焊技术制造制品，因为这种芯材料在钎焊温度下具有最佳的下垂阻力，并且由于其具有约1160°F的固相线 至1180°F，可热处理至最低屈服强度为12,000 psi，具有耐腐蚀性。 还可以提供可热处理的包层合金，用作单独的或与这种芯材料和其它合适的芯材料的钎焊组分。 优选的包层合金具有约1,065°-1.85°F的液相线，具有约20°至40°F的窄熔点范围，具有耐腐蚀性，并提供最佳强度和质量的接头。
