| || ||Sometimes it is better to make an alloy of copper to change or improve its properties. For example, an alloy might be stronger, have better corrosion resistance or a brighter colour. |
Brass, which is made by melting copper and zinc together, is harder, stronger, more corrosion resistant and has an attractive gold colour. It still keeps its anti-bacterial properties, which makes it a great material for door knobs, handrails and plumbing fittings.
