336.0-T551 Cast Aluminum
336.0-T551 aluminum is 336.0 aluminum in the T551 temper. The graph bars on the material properties cards below compare 336.0-T551 aluminum to: ANSI/AA cast aluminums (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
