Because they corrode and stain on skin contact.

Iron is more reactive than copper
Copper and iron do not typically react together to produce a specific compound or mixture. They are mainly used as individual elements for various applications due to their unique properties.
Iron is more reactive than copper, so when iron is added to copper sulfate solution, iron displaces copper in the reaction and forms iron sulfate. This process is known as a displacement reaction. This allows copper to be extracted from copper sulfate solution using iron.
No, bronze is an alloy traditionally made by combining copper with tin. Iron and zinc are not typically used in the production of bronze.
aluminum, copper, gold, iron, and petroleum products
copper, bronze and iron in that order
Yes, iron can displace copper from solutions of its salts through a displacement reaction. Iron has a higher reactivity than copper, so it can replace copper in the salt solution, forming iron salts and copper metal.
Iron is commonly used to reclaim copper from a used copper chloride solution through a displacement reaction. When iron is added to the solution, it reacts with the copper ions to form iron chloride and copper metal, allowing the copper to be easily recovered.
Since iron (Fe) is more reactive than copper (Cu) it will be 'plated' with copper when the metal iron is stuck in copper sulfate solution. Fe(s) + Cu2+(aq) + [SO42-]aq ---> Fe2+(aq) + Cu(s) + [SO42-]aq
copper is a more better conducter than iron and therefore is able to pass more heat than iron. basically copper wires are used in many instances and domestic needs as it is cheaper and can resist electricity
They use steel, iron, and sometimes copper to make a cell phone tower.
