The metal used in 2p coins is harder than pure copper because it is an alloy, primarily composed of copper and tin, or sometimes with other metals like zinc. This combination enhances the strength, durability, and resistance to wear and corrosion compared to pure copper, which is relatively soft and malleable. The alloying elements improve the overall mechanical properties, making the coins more suitable for circulation.
Copper metal is an element and thus a pure substance.

No. Copper is an element.
Hmmm...copper "is" a metal. Are you looking for a comparison between pure copper and various alloys made with copper?
Brass is harder than copper because it is an alloy made of copper and zinc, which gives it enhanced strength and durability compared to pure copper. The addition of zinc to copper alters its crystalline structure, making it more resistant to deformation and wear.
Copper coins are made of metal, as copper is a metal. However, most coins are not pure copper. In the US, the modern penny (one cent) is copper-coated zinc. There is copper in dimes, quarters and half-dollars as the inner "sandwich" of clad coins, between layers of zinc. There is also copper in the Presidential $1 coins, because the coins are made of brass (88.5% copper, with zinc, manganese, and nickel), the same alloy used in the earlier Sacajawea $1 coin.
No. Copper is a pure metallic element. Bronze is an alloy (an alloy is a mixture of two or more elements) of Copper usually with Tin as the main additive, but sometimes with other elements such as phosphorus, manganese, aluminum, or silicon. Bronze is harder and less malleable than pure metallic copper.

The metal composition of penny coins made after 1982 is 97.5 percent zinc and 2.5 percent copper. The first penny coins, from 1793 to 1837, were made from 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.
It depends on the alloy and temper of each material. Beryllium copper alloys are harder than the softest aluminum alloys, and high-strength aluminum alloys are harder than pure copper (which is quite soft). And almost every metal is harder than lead, except a few such as gold.
old ones that are pure silver, but most newer coins are mixed metal and have copper among other metals that concuct electricity mixed in!
Yes, :)
