This specification covers an aluminum alloy in the form of bars and rods 0.500 inch (12.50mm) and over in nominal diameter or least difference between parallel sides. These bars have been used typically for parts where moderate ductility, formability, and response to precipitation heat treatment are required and where distortion during machining must be minimized, but usage is not limited to such applications.
