Annealed (OS015) C75400 Nickel Silver

OS015 C75400 nickel silver is C75400 nickel silver in the OS015 (annealed to 0.015mm grain size) temper. The graph bars on the material properties cards below compare OS015 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.
