Pt-Ir Alloy Springs with Electrical Conductivity for Sensor Components

Platinum-iridium (Pt-Ir) alloy springs with electrical conductivity are engineered for precision, reliability, and high performance in sensor components. Typically composed of 90–95% platinum and 5–10% iridium, these springs offer a unique combination of mechanical strength, corrosion resistance, and consistent electrical conductivity.

Platinum ensures excellent chemical and oxidation resistance, while iridium enhances hardness, fatigue resistance, and high-temperature stability. This combination results in springs that maintain dimensional stability, precise spring force, and electrical connectivity, even in high-cycle, high-temperature, or corrosive environments.

DLX employs vacuum induction melting, precision wire drawing, and controlled annealing to produce springs with uniform microstructure, minimal residual stress, and superior mechanical and electrical performance. These processes ensure the springs meet the exacting requirements of modern sensor components.
