Iridium is a chemical element with symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, iridium is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser, and is the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Although only certain molten salts and halogens are corrosive to solid iridium, finely divided iridium dust is much more reactive and can be flammable.

Chemical Series
Metal, Transition metal, Group 9 element, Period 6 element, Toxic heavy metal Iridium is the most corrosion-resistant material known.
It is used in special alloys and forms an alloy with osmium, which is used for pen tips and compass bearings. It was used in making the standard meter bar, which is an alloy of 90% platinum and 10% iridium. It is also used for the contacts in spark plugs because of its high melting point and low reactivity.
Rice Puller
For Iridium (Copper Iridium) in the following forms: Rice Puller, Rice Toucher, Rice Repeller (Rice Thrower), Clove Puller, Clove Toucher, Flame Bender, items which burn (ignite) match sticks also those items performing just the Torch Test. *Any item which attracts rice like a magnet is called a Rice Puller . *These are some of the terms and phrases used to search for information on the internet and outernet (i.e. the physical world): RicePuller, Rice Puller, Rice Pullers, Rice Pulling, Copper Rice Puller, Copper Coin, Copper Iridium Rice Puller, Copper Iridium Coin, Copper Iridium Rice Pulling Coin, iridiumcopper, Iridium Copper, copperiridium, Tamarind Pulp, Lebbo, Lebo, Libon, Lebbon, Libbo Iridium Copper Coin, Lebbon Iridium Copper Coin, Copper Iridium Lebbo Coin, Lebbo Iridium Copper Coin, Libo, Attract Rice, Repel Rice, Rice Repellers, Rice Repellers, Rice Repeler, Rice Repelers, Rice Throw, Rice Thrower, Rice Throwers, Ricerepellers, Ricethrow, Ricethrower, Ricethrowers, Ricerepelers, Ricerepeler, Ricerepelers, Throw Rice, Rice Dust, Rice Dusting, Clove Puller, Clove Toucher, Flame Bender, Torch Test. *Copper Iridium pulling Coins are very magical. They will stop a bus when carried in it (stop ignition), but when wrapped in carbon papers the bus starts again. A candle flame bends towards this coin. When rice is brought near this it attracts rice. There is a small device in Germany which is about 1 million dollars and it absorbs this power from the coin. And there is one more coin called 1616 it has three magical points when plucked power in entire area is lost. 0.1 million dollar chemicals are used to test this coin near sea shore and these coins are very costly.
