Abstract:
Alcoa - Massena Operations is a totally integrated aluminum producer from primary production to fabricated rod, wire and bar products. Alcoa - Massena Operations currently offers sixteen different alloys of forging stock; eight of these have a wide usage in a variety of aerospace applications. Alcoa - Massena Operations can offer both O (annealed) and F (as-fabricated) tempers in both Class I and Class II product forms. Class II forging stock offers two to ten times tighter tolerances from a diameter standpoint than those of Class I. Available alloys now include 2219 and 2618 designed for high-temperature use and 4032 alloy for high-temperature wear performance (e.g. aircraft pistons). Alloy 7475 is also available, it offers microstructural control to provide superior fracture toughness properties.Details concerning structure-property relationships and overall facility support to these products and their respective applications will be presented. Capabilities for both aerospace cold-finished rod and bar products along with wire capabilities for aerospace fasteners are listed as well.
