Beryllium Copper Wire for Pacemaker Leads

Beryllium copper wire for pacemaker and defibrillator leads is drawn ultra fine and coated with platinum or gold, built to survive millions of flex cycles. With more than 50 years in high performance copper alloys, NGK Berylco supplies strip, wire, rod, plate and block from its European operations, with a dedicated UK office in Salford for local support.

In cardiac devices, high conductivity beryllium copper wire is drawn to very fine diameters and coated with platinum or gold to make leads for pacemakers and defibrillators, which endure millions of stress cycles over many years. Berylco wires are also made into springs for respiratory protection and resuscitation equipment, pressure regulators and non-return valves, chosen for their resistance to ignition in oxygen rich environments.

Beryllium copper is used in thin stamped diaphragms for stethoscopes, blood pressure monitors and other sensitive pressure instruments, improving sensitivity to mechanical and sound waves and supporting accuracy of ±2 mmHg.

It also forms the terminals of miniature and subminiature connectors in endoscopic cautery instruments, ECG and cardiac monitors and nerve stimulation systems, where connectors face frequent sterilisation and repeated mating.

The core Berylco grades are C17200 (CuBe2, Berylco 25) for high strength, C17300 (CuBe2Pb, Berylco 33/25) for free machining and C17510 (CuNi2Be, Berylco 14) for high conductivity. Where a beryllium-free option suits better, the GMX copper-nickel-tin range covers it. NGK's technical team can help match grade, temper and form to the job.

NGK Berylco is certified to ISO 9001, EN 9100, ISO 14001 and ISO 45001. It also runs a scrap recycling and buyback programme, remelting recovered material into alloy of identical composition.
