At DLX, we specialize in the production of custom platinum iridium rings that combine unmatched precision, durability, and beauty. Whether you need high-performance components for industrial sensors or luxury materials for jewelry, our Pt-Ir rings are engineered to deliver exceptional results in every environment.
Platinum Iridium alloys have long been valued for their mechanical strength and corrosion resistance. By introducing iridium into platinum, the alloy gains increased hardness and improved performance under thermal stress. This makes Pt-Ir rings ideal not just for aesthetic appeal but also for critical engineering applications.
DLX manufactures rings with compositions ranging from Pt90Ir10 to Pt70Ir30. These alloys maintain stability up to 1800°C, resist oxidation, and remain dimensionally accurate over time — key features for both scientific and jewelry-grade applications.

Pt-Ir rings have found their way into two very different but equally demanding worlds: luxury jewelry and industrial precision instruments.
In jewelry, Pt-Ir’s brilliance and durability make it an excellent alternative to pure platinum. It resists scratching and deformation, maintaining polish and shape for years.
In industrial settings, Pt-Ir rings are used in high-temperature furnaces, analytical equipment, aerospace sensors, and electrical contacts — places where both conductivity and structural integrity matter.
Our rings are tailored to meet each customer’s exact specifications, from inner diameter to surface finish and purity.
The demand for platinum group metals (PGMs) in high-tech manufacturing continues to grow. As industries seek materials that can endure harsh environments — from space exploration to clean energy — Pt-Ir alloys are becoming increasingly essential. At the same time, sustainable jewelry markets are embracing Pt-Ir for its longevity and ethical value.
DLX stays ahead of this trend by offering customized alloys and micro-fabrication capabilities that serve both functional innovation and aesthetic craftsmanship.

DLX’s production capabilities are rooted in decades of metallurgical experience. Our process begins with high-purity raw materials, refined and melted in a controlled vacuum environment. The alloy is then shaped through forging and precision rolling to achieve flawless homogeneity.
Our machining technology allows tolerances down to microns, ensuring perfect circularity and consistent wall thickness — vital for sensor rings, connectors, and laboratory instruments.
We also provide mirror-polished finishes for jewelry clients and custom alloy ratios for research institutions or aerospace projects.
Every DLX Pt-Ir ring undergoes strict inspection using:
X-ray fluorescence (XRF) for chemical composition
Optical microscopy for surface analysis
Dimensional verification using laser metrology
These measures ensure every batch meets the required DIN 17744 or ASTM B684 specifications, making DLX a trusted global supplier.

Building Stronger Partnerships
We support all kinds of testing:
1. What is a Platinum Iridium (Pt-Ir) alloy?
A Platinum Iridium alloy is a blend of platinum and iridium, typically containing 5–30% iridium. It combines platinum’s corrosion resistance with iridium’s hardness and wear resistance, resulting in an exceptionally durable and stable material.
2. Why is the Pt-Ir alloy used for rings?
Pt-Ir alloy rings are chosen for both jewelry and precision industrial applications because they maintain shape, resist scratching, and remain stable even in high-temperature or chemically aggressive environments.
3. What’s the difference between pure platinum and Pt-Ir alloy?
Pure platinum is softer and more ductile, while Pt-Ir alloy is stronger and more wear-resistant. For jewelry and precision rings, Pt-Ir offers better longevity and mechanical performance.
4. What are common iridium content ratios in Pt-Ir alloys?
Typical compositions include Pt90Ir10, Pt80Ir20, and Pt70Ir30. Each grade offers different mechanical strength, hardness, and oxidation resistance depending on the application.
5. Are Pt-Ir rings suitable for both decorative and functional use?
Yes. They are used in high-end jewelry, scientific instruments, precision measurement devices, and aerospace sensors. The alloy’s beauty and technical stability make it versatile.
6. How are DLX’s Pt-Ir rings manufactured?
DLX uses precision vacuum melting and micro-machining to ensure tight tolerances and uniform microstructure. Our production includes forging, rolling, drawing, and CNC machining for exact dimensions.
