Beryllium copper Brush 25 achieves the highest strength and hardness available among all copper alloys after age hardening, and is consequently very widely used. It exhibits excellent bendability and general formability prior to ageing, especially in the tempers A (TB00), ¼ H (TD01) and ½ H (TD02). After forming and in the fully age hardened condition, the alloy Brush 25 provides a unique combination of very high strength and high conductivity, high fatigue strength limit and an excellent thermal strength relaxation behaviour.

Typical uses
Spring contacts, diaphragms, bellows, electric and electronic contacts and connectors, switches, relays, bearings, resistance welding electrodes, various parts for the watch industry such as wheels, watch hands, balances, levers etc.
