Annealed 85-Silver 15-Nickel Alloy

Annealed 85-silver 15-nickel is 85-silver 15-nickel in the annealed condition. It has the lowest strength compared to the other variants of 85-silver 15-nickel. The graph bars on the material properties cards below compare annealed 85-silver 15-nickel to: precious metal electrical contact alloys (top), all alloys in the same category (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.
