Zinc (Zn)- Lead (Pb)- Copper (Cu)
Zinc is mainly used to galvanise steel or iron – that is, to apply a zinc coating to stop it rusting. Galvanised steel is used in buildings, cars, white goods and electronics.
The strength and flexibility of zinc alloys mean they are widely used to create die casts for industrial uses – for example, in the production of car or machine parts. Zinc is also used to make brass and bronze.
Zinc oxide is mainly used in the production of rubber, while zinc sulphide has uses such as X – ray screens, in optics, and as a pigment.
Lead (Pb) & Copper (Cu)
Lead has a wide range of industrial uses including batteries, undersea cables, weights, solders and radiation protection.
Copper has a vast range of household and industrial uses.
Its superior electrical conductivity makes it ideal for electronics, such as wiring and computer connections; and its ability to heat up and cool down quickly makes it ideal for heat exchange applications such as air conditioners.
The metal is easily recycled, and also used in renewable energy technologies such as solar cells and electric vehicles – so it has a vital role to play in a sustainable future.
Copper’s antimicrobial properties also help infection control in hospitals and care environments.
