C17200 Beryllium Copper for Watch Balance Wheels in Luxury Watchmaking

NGK positions C17200 Beryllium Copper for watch balance wheels in luxury watchmaking. C17200, or CuBe2 / Berylco 25, is described by NGK as the reference beryllium copper alloy across strip, rod, wire and other forms. It reaches the highest mechanical strength and hardness of any copper alloy after age hardening while still offering good formability, fatigue strength and stress-relaxation resistance. Watchmakers value spring behaviour, formability and appearance in tightly toleranced parts. That makes it a sensible fit when engineers want reliable performance, long service life and cleaner production outcomes.
