What does 10 Irid plat mean?
This means it is an alloy of very high purity. The most widely used platinum alloys are either 90% platinum with 10% iridium (shown ‘10% irid.
What is platinum iridium used for?
platinum–iridium, alloy of platinum containing from 1 to 30 percent iridium, used for jewelry and surgical pins. A readily worked alloy, platinum–iridium is much harder, stiffer, and more resistant to chemicals than pure platinum, which is relatively soft.
What is platinum iridium alloy?
The IPK is a roughly golfball-sized object made of a platinum alloy known as “Pt‑10Ir”, which is 90% platinum and 10% iridium (by mass) and is machined into a right-circular cylinder with height equal to its diameter of about 39 millimetres to reduce its surface area.

Does platinum have a resale value?
Platinum also has poor resale value as only a limited number of shops buy it back. Besides, compared with gold jewellery, making charges, close to Rs 500 per gram, are much higher for platinum jewellery. Buyers also need to be cautious when it comes to the purity of the metal and what it is mixed with.
Are platinum rings 100% platinum?
Platinum jewelry is rarely made with 100% pure platinum. Instead, platinum is mixed with similar metals or non-precious base metals. Generally, jewelry with a higher percentage of pure platinum is worth more….Platinum Jewelry.

What is the importance of using platinum and iridium in standard meter?
Pt-Ir alloy is stiffer and more resistant to chemicals and wear and tear than pure platinum. It also has a low thermal coefficient of expansion, which means that its structural fluctuations with changes in temperature is also low. These are the reasons why the Pt-Ir alloys were used for defining the IPK and IPM.
What is the importance of using platinum and iridium alloy in the standard meter?
The 10% iridium 90% platinum alloy was chosen in making prototype metre and kilogram because of its high density, corrosion resistance and stability. Was this answer helpful?
What is the price of Iridium in 2021?
The average annual price for iridium in 2020 was 2,550 U.S. dollars per troy ounce. The price of iridium dramatically increased in March 2021, to 6,000 U.S. dollars per troy ounce as a result of supply shortages combined with its prospective use to produce green hydrogen.
What is platinum/iridium Pt 90/IR 10 alloy?
Platinum / Iridium Pt 90 / Ir 10 alloy has been used in “non-standard” thermocouples, electrical contacts and for electrodes in medical research. The alloy is harder and mechanically stronger than Platinum. The key properties of Platinum / Iridium Pt 90 / Ir 10 alloy are tabulated below.
What are the uses of platinum iridium alloys?
Other uses of platinum iridium alloys include electrical contacts, spark plugs, electro explosive devices, medical leads and electrodes, thermistors, catalytic applications, jewelry, pen points, surgical pins or pivots and the kilogram and meter standards used by the department of weights and measures.
What is 80/20 plat iridium alloy?
The 80/20 Plat Iridium alloy is very hard and dense, and is sometimes used in the production of fine wirework.
What is the best iridium for jewelry?
Because of these advantages 90/10 Plat Iridium has traditionally been one of the most important jewelry alloys used in the USA, although there has recently been a swing toward alloys of 95/5 Plat Iridium. Some manufacturers in Germany and Japan also prefer the 95/5 alloy.
