ASTM A228 Music Wire vs. N06007 Nickel

ASTM A228 music wire belongs to the iron alloys classification, while N06007 nickel belongs to the nickel alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is ASTM A228 music wire and the bottom bar is N06007 nickel.
