1. What are Platinum Iridium Springs?
Platinum Iridium Springs are precision coil springs manufactured from platinum-iridium alloys. They are selected for environments requiring exceptional corrosion resistance, chemical stability, reliability, and long-term dimensional performance.
2. What platinum-iridium alloys are available?
Common compositions include Pt90Ir10 and Pt95Ir5, while custom platinum-to-iridium ratios can be sourced for specialized applications.
3. What are Platinum Iridium Springs used for?
They are used in medical devices, laboratory instruments, chemical equipment, electrical components, precision instrumentation, aerospace systems, and specialized high-temperature or corrosive environments.
4. Can custom spring dimensions be manufactured?
Yes. REG Metals can source springs with custom wire diameter, coil diameter, free length, number of turns, spring rate, working load, deflection, end configuration, and dimensional tolerances.
5. Why use platinum-iridium instead of conventional spring alloys?
Platinum-iridium provides exceptional corrosion resistance, chemical stability, oxidation resistance, and dimensional stability, making it particularly useful where conventional stainless steel, nickel alloys, or other spring materials may not provide the required performance.
6. Does REG Metals provide a Certificate of Analysis?
Yes. A Certificate of Analysis (COA) can be supplied documenting platinum and iridium composition, wire dimensions, mechanical properties, spring dimensions, tolerances, surface condition, and other applicable specifications.
