Quarter-Hard (H01) C75400 Nickel Silver
H01 C75400 nickel silver is C75400 nickel silver in the H01 (quarter hard) temper. The graph bars on the material properties cards below compare H01 C75400 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.
