Platinum Iridium Spring Wire for Precision Load Control with Chemical Stability and Long-Term Mechanical Reliability

Platinum Iridium (Pt-Ir) Spring Wire is a high-performance alloy designed for applications demanding precision load control, chemical stability, and long-term mechanical reliability. Composed of 90–97% platinum and 3–10% iridium, this alloy combines platinum’s exceptional corrosion resistance with iridium’s hardness and wear resistance, ensuring consistent spring properties in harsh environments.

DLX manufactures Platinum Iridium Spring Wire using vacuum induction melting, fine wire drawing, and heat treatment processes, delivering high-purity, uniform microstructure, and tight dimensional tolerances. These wires are ideal for sensors, micro-actuators, laboratory instruments, and high-reliability medical devices where consistent elasticity, fatigue resistance, and chemical stability are critical.

Applications

Platinum Iridium Spring Wire is widely applied in:

• Precision Sensors: Load cells, pressure transducers, and micro-actuators requiring exact force response.

• Laboratory Instruments: Electrodes, analytical devices, and high-precision measurement tools.

• Medical Devices: Implantable sensors, surgical instruments, and pacemaker components.

• Aerospace Applications: Micro-sensors, actuators, and components exposed to high temperatures or harsh environments.

• Energy Sector: High-temperature probe supports and corrosion-resistant spring assemblies.

• Luxury Instrumentation: Fine mechanical controls in watches and micro-mechanical assemblies.
