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.
