Materials / Phosphor Bronze Materials

Phosphor Bronze Materials

Phosphor bronze is a copper-tin-phosphorus alloy known for its exceptional spring properties, fatigue resistance and corrosion resistance. These characteristics make phosphor bronze stamping the preferred choice for components that must maintain contact force and electrical performance over millions of cycles.

Material Properties

Spring PerformanceExcellent elastic limit and fatigue resistance
ConductivityModerate (≈15% IACS) but stable under repeated flexing
Corrosion ResistanceVery good in atmospheric and marine environments
FormabilityGood; suitable for bending, forming and progressive stamping
FinishingTin or nickel plating; passivation for contact applications

Typical Applications

Spring contacts & clipsRelay & switch componentsConnector terminalsBellows & diaphragmsFuse clipsElectrical sockets

Stamptek produces precision phosphor bronze parts — spring contacts, clips, relay components and connector terminals — with controlled grain structure and burr-free stamping, ensuring consistent elastic behavior and long service life.
