Ultra High Strength C17200 Beryllium Copper Sheet for Precision Spring Parts

C17200 is classic high-strength beryllium copper alloy,obtains supreme mechanical property after age hardening treatment,ranks top-tier strength among all commercial copper-base alloys.

Outstanding elastic limit performance,stable elastic output under complex stress environment,suitable for miniaturized thin spring structure design of high-end electronic devices.

Excellent high-temperature stress-relaxation resistance,retains stable contact force under 120-180 long-term working condition,prevents contact failure caused by elastic attenuation.

Superior anti-fatigue property,supports millions-level repeated plug-in and cyclic switching,without permanent deformation under long-term high-frequency vibration load.

Good bending performance before heat treatment; after solution annealing,it can realize complex precision stamping; non-magnetic and spark-proof property satisfies special industrial safety requiremen

Uniform plate flatness,tight thickness tolerance,stable plating performance for tin,nickel and gold plating; good corrosion resistance adapts to harsh atmospheric and electronic working environment.
