It is so easy to test. you have to buy a "UJALA" then take a glass of water and put the coin in it and then again put three drops of ujala.If the coins consume ujala less than 30 minutes and the water turn into white you are sure that the coin has iridium. After two days you have to do niddle test.Put the niddle near the coin and if the coin attract it towards it you are 100% sure that coin contains iridium not repeat test again and again because it might loss its power.

Are copper coins pure copper?
Pure copper has not been used to make British coins for about 150 years. From 1860, British "copper" coins were made from bronze which consisted mostly of copper varying from 95 to 97% copper. From 1992, British "copper" coins were made from copper plated steel. Ironically, copper is used to make modern "silver" coins (cupro-nickel) consisting usually of 75% copper and 25% nickel.
What element is mixed with copper to make coins?
Up until recently, copper coins contained very small quantities of tin, zinc or even aluminium, and were perhaps more accurately referred to as bronze coins. Currently, due to the increasing cost of copper, there is a trend away from minting copper coins, and many, what were previously copper coins, are now being made from copper plated steel.
Why do copper coins go dull?
because the old copper coins are made of pure copper but they had to make them out of different matierials because the copper the coin was made of was worth more than the coin itself, therefore people were melting down copper coins and selling the copper. the new coins are now made of a small percent of copper and more iron.
Why are coins made of copper?
Coins are made of copper because copper is a highly durable and malleable metal that is readily available. Its resistance to corrosion also makes it ideal for minting coins that are meant to be in circulation for a long time. Additionally, copper is a cost-effective material for producing coins.
What is the usage of iridium copper?
Iridium copper is used primarily in electrical applications due to its high conductivity and corrosion resistance. It is commonly used in switches, relays, and connectors within the electronics industry. Its high melting point and durability make it suitable for applications where extreme conditions are present.
Can we mix the iridium in melt copper?
Iridium can form alloys with copper.
Who are the buyers of copper iridium?

What is copper iridium?
Copper iridium is a binary alloy composed of copper and iridium. It is known for its high hardness, good wear resistance, and high temperature stability, making it useful for applications such as electrical contacts, spark-resistant tools, and high-performance bearings.
Where iridium coins available?

When will copper metal change into iridium?
It cannot without radioactive decay, and it is impractical to imagine copper (element 29) undergoing enough positron emissions to become iridium (element 77). There is no chemistry which can possibly turn copper into iridium, and no known physics either.
Is any business happened regarding copper iridium metal?
