ASTM B780 Alloy vs. C14510 Copper
ASTM B780 alloy belongs to the otherwise unclassified metals classification, while C14510 copper belongs to the copper alloys. 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 (14, in this case) are not shown.
For each property being compared, the top bar is ASTM B780 alloy and the bottom bar is C14510 copper.
