Abstract: 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.

Abstract: A free machining aluminum alloy contains an effective amount of one or more high melting point constituents that provide enhanced machining capability. The high melting point constituents occupy from about 0.1 to about 3.0 volume percent of the aluminum alloy. The constituents can be any material that is essentially insoluble in the aluminum alloy matrix so as to form a discontinuity and one that will resist deformation during machining to enhance the formation of voids between the matrix and the free machining constituents. The constituents include elements, nitrides, oxides, borides, carbides, silicides, aluminides and combinations thereof that have a high melting point and high strength and low solubility in aluminum at the elevated temperature so that the constituents resist deformation during the machining operation. The free machining aluminum alloy can be formed as a workpiece and subjected to any machining operation.

Abstract: An aluminum alloy article consisting 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 is adapted for use as a connector block in a heat exchanger assembly. The connector block has a connector block body with at least one machined portion therein and is configured to be brazed to a portion of the heat exchanger, particularly the heat, exchanger header. The aluminum alloy combines the properties of machinability, corrosion resistance, strength and brazeability. A connector block made from the aluminum alloy can be machined to the right configuration and can be brazed to the heat exchanger header to form a high quality brazed joint. In addition, the connector block can withstand the corrosive environment associated with the heat exchanger and has the necessary mechanical properties to interface with other heat exchanger components.

Abstract: An aluminum alloy composition includes controlled amounts of iron, manganese, zinc, zirconium, vanadium, and titanium to effectively inhibit grain growth during exposure to elevated temperatures while maintaining extrudability and corrosion resistance. The composition is especially adapted for use as micro-multivoid tubing for brazed heat exchanger applications and has a post-braze grain structure that is more resistant to intergranular corrosion so as to reduce or eliminate heat exchanger failures during service.
