Cold-rolled Z21210 Zinc vs. Work Hardened ASTM B685 Alloy
Cold-rolled Z21210 zinc belongs to the zinc alloys classification, while work hardened ASTM B685 alloy belongs to the otherwise unclassified metals. There are 10 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 cold-rolled Z21210 zinc and the bottom bar is work hardened ASTM B685 alloy.
