Reactor Grade Zirconium vs. Type 1 Magnetic Alloy

Reactor grade zirconium belongs to the otherwise unclassified metals classification, while Type 1 magnetic alloy belongs to the iron alloys. There are 18 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is reactor grade zirconium and the bottom bar is Type 1 magnetic alloy.
