Platinum Iridium Springs for Aerospace and Automotive Engineering

Platinum-iridium (Pt-Ir) springs are engineered for extreme durability, precision, and high-performance reliability in aerospace and automotive engineering. Typically composed of 90–95% platinum and 5–10% iridium, these springs offer a perfect balance of corrosion resistance, mechanical strength, and fatigue endurance.

Platinum ensures resistance to oxidation and chemical degradation, while iridium contributes hardness, tensile strength, and high-temperature stability. This combination produces springs that maintain consistent force, dimensional stability, and mechanical integrity under the high-stress, high-cycle conditions commonly encountered in aerospace and automotive applications.

DLX employs vacuum induction melting, precision wire drawing, and controlled annealing to achieve uniform microstructure, minimal residual stress, and superior fatigue performance. Each spring is crafted to perform reliably in critical engineering systems where safety and precision are paramount.
