Platinum iridium alloy

WebbPlatinum-iridium alloys (5 to 10 percent iridium) are readily workable metals that are much harder and stiffer and more resistant to chemical attack than the soft pure platinum. … Webb2 sep. 2009 · Iridium, discovered in 1804, comes from the Latin word iris, meaning rainbow. It was so named because of its colorful salts. Iridium is known as a "platinum metal" because it is found in natural deposits of platinum (#78) and along with osmium (#76), its twin element. Iridium's most common application is as an alloying agent for hardening …

WebbPlatinum-rhodium alloys are employed in the production of thermocouples that are capable of measuring temperatures as high as 1,800 °C (3,270 °F). Palladium is used in both the pure and alloyed states for a variety of electrical applications (accounting for 50 percent of consumption) and for dental alloys (30 percent of consumption). WebbIridium alloys with platinum in all proportions and alloys containing up to about 40% iridium are workable, although considerably harder than pure platinum. The creep resistance of iridium–platinum alloys is better than that of rhodium–platinum alloys at temperatures below 500 °C.
