Full-hard AISI 205 vs. Full-hard Nickel 690
Full-hard AISI 205 belongs to the iron alloys classification, while full-hard nickel 690 belongs to the nickel alloys. They have a modest 28% 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 (6, in this case) are not shown.
For each property being compared, the top bar is full-hard AISI 205 and the bottom bar is full-hard nickel 690.
