Iridium can form alloys with copper.
silver and clad(clad is a mix of silver and copper).

Iridium is a very rare element in Earth's crust, however rocks that have an age equal to that of the K-T boundary are significantly enriched in iridium. It is theorised that this enrichment is due to the impact of an asteroid with Earth (as asteroids are rich in iridium and the resultant massive explosion spread iridium enriched debris all over the world). This asteroid impact is thought to have been a significant event in the mass extinction even that wiped out the dinosaurs. This is known as the Alverez hypothesis. For more information, please see the related link.
Iridium is a superconductor. As a result it probably is not magnetizable in the same sense as is iron. Substances that are capable of holding a permanent magnetic field usually are not superconductors.
Aerogel, i think. It may be hydrogen.
The buyers of copper iridium including coin minting companies.
Iridium is obtained as a by-product in the nickel or copper production.
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.
Melt copper and a small amount of zinc together. Mix thoroughly and cool.

In the year 1616, when British people had establish east India company, there was a very long solar eclipse, During that period the Indian saints had discovered a rare element Iridium, which was believed to have no-corrosion properties, it is believed that these pieces of iridium came from mateiors falling on the earth, Generally meteior burn off due to air friction when they enter the earths atmosphere. but iridium having a very high melting point survived all the heat and finally fall on earth. Iridium is a very very rare and costly metal. In those days, when the british government came to knew about these metal, they decided to mix it with copper to make non-corrosive currency and utensils. It was later found that the compound copper iridium had magical properties like pulling a rice coin , affecting electronic equipment in its vicinity and so on.

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.
Only if the acid is above the melting point of copper. However, the copper might dissolve in acid if the acid is oxidizing. If it did, copper ions would be present in the solution formed, but there would not be an metallic copper in it.
It is possible to melt metals including copper. It requires a very high level of heat, depending on the metal.ADDED@ Not sure why that "and copper". Copper IS a metal.
