Extra-Hard (H06) C73100 Nickel Silver
H06 C73100 nickel silver is C73100 nickel silver in the H06 (extra hard) temper. It has the highest strength and lowest ductility compared to the other variants of C73100 nickel silver. The graph bars on the material properties cards below compare H06 C73100 nickel silver to: wrought copper-nickels (top), all copper alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
