When it comes to high-performance materials that combine strength, elegance, and reliability, platinum-iridium alloy rings lead the way. At DLX, we focus on developing and manufacturing precision Pt-Ir alloy components that meet the needs of both high-end jewelry makers and demanding industrial users.
Platinum-iridium alloys are renowned for their exceptional mechanical properties and stability under extreme conditions. The addition of iridium—an element even harder and more corrosion-resistant than platinum—enhances the metal’s overall durability and hardness. DLX’s platinum-iridium rings are crafted from alloys such as Pt90Ir10, Pt80Ir20, and Pt70Ir30, each optimized for specific performance needs.
The alloy’s high melting point and structural integrity make it ideal for both ornamental and technical applications. Whether used in fine jewelry or high-temperature sensors, these rings offer lasting value and dependable performance.
DLX platinum-iridium alloys are refined through precision vacuum melting and forging techniques. This ensures a uniform microstructure and eliminates impurities that could affect conductivity or mechanical properties. The resulting product offers:
Excellent oxidation and corrosion resistance
High hardness and wear performance
Consistent electrical stability
Dimensional accuracy under thermal stress
