Premium platinum-iridium (Pt-Ir) compression springs are designed for extreme durability, high fatigue resistance, and long-term reliability. Typically composed of 90–95% platinum and 5–10% iridium, these springs are ideal for high-stress industrial, aerospace, and precision engineering applications.
Platinum provides outstanding corrosion resistance, chemical stability, and thermal resilience, while iridium enhances hardness, tensile strength, and fatigue resistance. The combination ensures that Pt-Ir compression springs maintain dimensional stability, consistent force output, and mechanical integrity even under repeated high-load cycles.
DLX employs vacuum induction melting, precision wire drawing, and controlled annealing to produce a uniform microstructure with minimal residual stress, ensuring superior elasticity, wear resistance, and long-term performance.
