Pt30Ir Alloy Springs with Superior Fatigue Resistance

Pt30Ir alloy, composed of 70% platinum and 30% iridium, is a high-performance material engineered for exceptional fatigue resistance, mechanical strength, and thermal stability. Platinum provides excellent corrosion and oxidation resistance, while iridium enhances hardness and durability under repeated stress. This combination creates springs that maintain consistent mechanical properties, dimensional stability, and electrical conductivity in demanding applications.

DLX uses vacuum melting, precision wire drawing, and controlled annealing to ensure uniform microstructure and minimal residual stress. These processes produce springs that can withstand high-cycle loading and extreme environmental conditions without significant deformation or loss of spring force.
