Quarter-Hard 90-Silver 10-Cadmium-Oxide Alloy

Quarter-hard 90-silver 10-cadmium-oxide is 90-silver 10-cadmium-oxide in the quarter-hard temper. The graph bars on the material properties cards below compare quarter-hard 90-silver 10-cadmium-oxide 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.
