Question

Write the general characteristics of coinage metals.

Answer 1

1. They possess high ductility and malleability, making them easy to shape.
2. These metals have excellent electrical and thermal conductivity.
3. They are resistant to corrosion and oxidation, retaining their lustre.
4. They exhibit metallic lustre with a shiny appearance.
5. Coinage metals have moderate to high melting points.
6. They show good corrosion resistance, especially gold and silver.
7. They are chemically less reactive compared to other metals.
8. Their crystal structure is typically face-centred cubic (fcc), aiding in their malleability.
