Mild steel is made up mainly of iron. Rusting of mild steel can be prevented using a process known as galvanising. Copper is not a particularly strong metal. However, when it is combined with a suitable metal, a strong alloy called brass is formed. Which of the statements is correct?
- ACopper corrodes very quickly when wet and brass does not.
- BCopper is mixed with zinc to produce brass.
- CGalvanising mild steel changes it from a pure metal into an alloy.
- DWhen a steel object is galvanised this means it is coated with a thin layer of tin.
