Why this grade
Limited thermal stress relaxation, so contacts keep their force at elevated temperature.
Fatigue resistance over repeated mating and unmating cycles.
Lead addition for free machining of precision contact parts.
Used in connectors as an alternative to beryllium and cadmium copper alloys.
