Alloy 290 strip provides the highest strength of any mill hardened copper alloy, with electrical conductivity considerably greater than other high strength copper alloys. This alloy features good stress relaxation resistance and high fatigue strength. Typical applications include high reliability spring contacts for battery contacts, audio jack contacts, and board to board contacts.
