413.0 Aluminum vs. ASTM A229 Spring Steel
413.0 aluminum belongs to the aluminum alloys classification, while ASTM A229 spring steel belongs to the iron alloys. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.
For each property being compared, the top bar is 413.0 aluminum and the bottom bar is ASTM A229 spring steel.
