Platinum-iridium tubes are among the most durable and stable materials used in modern industry, especially in environments that demand extreme corrosion resistance and high-temperature performance. At DZX, we manufacture Platinum Iridium (Pt-Ir) tubes that conform to ASTM B684 standards—ensuring consistency, purity, and superior oxidation resistance across every production batch. Designed for precision, durability, and chemical stability, our Pt-Ir tubes are used in aerospace, medical, laboratory, and high-tech manufacturing industries where reliability matters most.
Material Analysis
The Platinum-Iridium alloy combines the noble qualities of platinum with the extreme hardness and wear resistance of iridium. Typically available in compositions like Pt-Ir 90/10 or Pt-Ir 80/20, the alloy exhibits a rare combination of toughness, ductility, and oxidation stability. Platinum provides excellent corrosion resistance and electrical conductivity, while iridium enhances mechanical strength and hardness—resulting in a tube capable of withstanding harsh operational environments.
The ASTM B684 standard ensures tight control over chemical composition, dimensional accuracy, and mechanical performance for platinum-based tubes, making them suitable for use in demanding electronic, medical, and industrial systems.
| Property | Pt-Ir 90/10 Tube | Pt-Ir 80/20 Tube | Nickel Alloy Tube | Stainless Steel Tube (316L) |
|---|
| Melting Point | ~1,800°C | ~1,820°C | ~1,400°C | ~1,500°C |
| Density | 21.5 g/cm³ | 21.7 g/cm³ | 8.9 g/cm³ | 7.9 g/cm³ |
| Corrosion Resistance | Excellent | Excellent | Moderate | Good |
| Oxidation Resistance | Superior | Superior | Limited | Moderate |
| Electrical Conductivity | High | High | Medium | Low |
| Strength at High Temp | Excellent | Exceptional | Moderate | Moderate |
| Workability | Good | Moderate | Good | Excellent |
| Standard | ASTM B684 | ASTM B684 | ASTM B163 | ASTM A213 |
Platinum-iridium’s exceptional resistance to oxidation even above 1000°C makes it ideal for high-vacuum or high-heat systems, outperforming conventional materials that degrade or lose stability under similar conditions.
