Full-Hard (H04) C73100 Nickel Silver

H04 C73100 nickel silver is C73100 nickel silver in the H04 (full hard) temper. The graph bars on the material properties cards below compare H04 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.
