Platinum iridium alloy
WebbPlatinum-rhodium-iridium alloys, obtained by the direct fusion of crude platinum, were found to be very resistant to corrosion and were frequently employed for coinage and for chemical plant ( 1, 2 ). 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 …

Did you know?
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. WebbPlatinum-iridium alloy Firmetal, 2024-9-1 09:40:00 PM It is a platinum-based binary alloy containing iridium, which is a continuous solid solution at high temperature. The solid phase decomposition occurs when the temperature reaches 975 ~ 700℃, but the phase equilibrium process is very slow.

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. Such alloys are used for jewelry, pen points, surgical pins and pivots, and electrical contacts and sparking points.

While not as hard as iridium, it still offers good durability over time. However, they tend to be more expensive than standard copper core or nickel alloy core plugs. Another significant difference between Iridium and Platinum spark plugs is their heat range rating. got createdWebbUses of Iridium: Used with osmium to tip gold pen points, to make crucible and special containers.
