Applications
Aluminum-copper alloy ASTM B26/B26M 222.0 is used for manifolds, valve bodies, ornamental grilles, reflectors and equipment frames. Foundry guidance also identifies food-handling applications. Other cast components used in this material family include housings, covers, cylinder-related castings, pump components and valve components. Applications include engines, machinery and other industrial equipment, including replacement parts.
Alloy condition and the recorded purchase specification remain applicable; broader literature does not extend that specification to aerospace procurement.
