C519 Bronze: Connector Qualification

C51900 belongs to the phosphor-bronze family. Material reference.

Connector Qualification

For a connector, compare alternatives at the same temper, section and contact geometry. Separate the spring-force requirement from the electrical and surface-finish requirements. A datasheet for straight strip does not qualify a formed and plated contact over its intended mating cycles.

Manufacturing and acceptance checks

Include the complete UNS designation, strip condition and stamping direction. Specify plating, contact force and the mating-cycle acceptance test. Ask how burrs and edge damage are controlled at the bend and contact surfaces, and inspect the final part rather than only the incoming strip.
