Nickel 690 vs. AWS BVAu-7

Nickel 690 belongs to the nickel alloys classification, while AWS BVAu-7 belongs to the otherwise unclassified metals. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 15 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.

For each property being compared, the top bar is nickel 690 and the bottom bar is AWS BVAu-7.
