7 Most Expensive Metals

7 Most Expensive Metals Metals are opaque, lustrous elements that are good conductors of heat and electricity. Each metal has its own value, depending on its rarity, its properties, and how you can find them. Metals are being used as valuable currency and they have also become a form of investment, seeing as they do not depreciate in value. There are some precious metals that are desirable for their aesthetic properties, and others that have properties that are ideal for industrial purposes. #7. Rhenium Produced in Chile, Kazakhstan, and the United States, Rhenium is one of the densest metals. It also has the third-highest melting point, which is why it is added to nickel-based superalloys as a means of improving the alloy’s temperature strength. #6. Osmium Ranked #6, this hard bluish-white transition metal, Osmium is one of the most expensive metals. This metal, even though dense, is usually used to make fountain-pen nib tipping and also for creating electrical contacts. #5. Iridium Then there’s this beautiful hard silvery-white transition metal- Iridium. It is the second densest metal on earth and also the most corrosion-resistant metal. It is special for a number of reasons. Iridium is found in meteorites and the earth’s crust. It is super rare and as such, expensive. #4. Ruthenium This precious metal is very rare with an annual production of just three tonnes. It is a chemical element with the atomic number 44 and the symbol RU. Discovered by Russian-born scientist, Karl Ernst Claus, in 1844, it is commonly found in ores with other platinum group metals in the mountains of North and South America. #3. Gold Gold is one of the most expensive metals in the world. In its pure form, this metal is a bright yellow, dense, soft, malleable, and ductile metal. It is one of the least reactive chemical elements on earth. Even though it is ranked 3rd, it is one of the most sought-after metals in the world. This is mostly because it retains its value even when there is economic deflation or inflation. #2. Palladium The Second most expensive precious metal in the world is Palladium. Palladium is a chemical element identified by the symbol Pd and its atomic number 46. Palladium has the lowest melting point and is the least dense of all metals on this list. #1. Rhodium The precious metal which is extremely rare, Rhodium, comes first on the list. It is a silver-white, hard, corrosion-resistant inert transition metal. It was named Rhodium by its founder, William Hyde Wollaston in 1803 due to its chlorine compounds. #mostexpensivemetals #preciousmetals #rhodium most expensive metals,top 10 most expensive metals in the world,most expensive,precious metals,most expensive things,metals,rhodium,platinum,gold,most expensive metals in the world,most expensive metals you didn't know,price comparison,palladium,expensive,rhenium,osmium,silver,diamonds,materials,indium,facts,in the world,expensive metal in the world,noble metal,californium,gold mining,californium 252,most expensive substances,cognitive dissonance
