Cold Worked Type 4 Magnetic Alloy vs. Work Hardened ASTM B685 Alloy
Cold worked Type 4 magnetic alloy belongs to the nickel alloys classification, while work hardened ASTM B685 alloy belongs to the otherwise unclassified metals. There are 17 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is cold worked Type 4 magnetic alloy and the bottom bar is work hardened ASTM B685 alloy.
