摘要： An aluminum alloy composition consists essentially of controlled amounts of iron, silicon, copper, manganese, magnesium, titanium, zinc, zirconium, and free machining elements with the balance being aluminum and incidental impurities. The alloy provides improvements in combined strength, corrosion resistance, machinability, and brazeability. A component or article made from the aluminum alloy can be machined to the right configuration and can be brazed to another component to form a high quality brazed joint. In addition, the article can withstand corrosive environments and has the necessary mechanical properties to interface with other components. The alloy is adapted for particular use as a component in a heat exchanger assembly, such as a connector block having one or more machined surfaces or passageways.

摘要： An aluminum alloy article containing the alloying amounts of iron, silicon, manganese, titanium, and zinc has controlled levels of iron and manganese to produce an alloy article that combines excellent corrosion resistant with good formability. The alloy article composition employs a controlled ratio of manganese to iron and controlled total amounts of iron and manganese to form intermetallic compounds in the final alloy article. The electrolytic potential of the intermetallic compounds match the aluminum matrix of the article to minimize corrosion. The levels of iron and manganese are controlled so that the intermetallic compounds are present in a volume fraction that allows the alloy article to be easily formed. The aluminum alloy composition is especially adapted for extrusion processes, and tubing that are used in heat exchanger applications.

摘要： One free machining aluminum alloy includes bismuth as a free machining elemental constituent that functions as a discontinuity in the aluminum alloy matrix rather than a low melting point compound. Using bismuth in weight percents of the total composition ranging between 0.1% and 3.0% improves both machinability and mechanical properties. The bismuth can act as a substitute for another free machining constituent in a free machining aluminum alloy or can be added to an aluminum alloy to improve its machinability. Another free machining aluminum alloy has bismuth and tin as free machining constituents for improved machining. When using bismuth and tin, the bismuth ranges between 0.1 and 3.0% by weight and the tin ranges between 0.1 and 1.5% by weight.

摘要： Methods of improving the corrosion resistance and hot working productivity of AA7000 series aluminum alloys include, in one mode, the steps of treating a stock material to form a globular microstructure, preferably by a thermal conversion treatment, and subsequently hot working the treated stock material, quenching it and aging it. The globular microstructure permits increasing the hot working rate to attain T6 properties using only a T5 temper practice and without adverse effect on the surface of the hot worked product as a result of the increased hot working rate. Consequently, an acceptable product is made at a significantly lower cost due to the increased hot working rates and fewer processing steps. The method also improves the corrosion resistance, particularly exfoliation corrosion resistance, of the product such that corrosion resistance generally attainable using only a T7 temper practice is achieved using only a T5 temper practice.
