90-Silver 10-Cadmium-Oxide Electrical Contact Alloy

90-silver 10-cadmium-oxide is a precious metal alloy formulated for use in electrical contacts.

The properties of 90-silver 10-cadmium-oxide include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 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.
