92-Silver 8-Tin-Oxide Electrical Contact Alloy

92-silver 8-tin-oxide is a precious metal alloy formulated for use in electrical contacts. It can have a moderately low tensile strength among the precious metal electrical contact alloys in the database.

The properties of 92-silver 8-tin-oxide include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 92-silver 8-tin-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.
