- Uses of
- ferrous Metals
- non-Ferrous Metals
Uses of Ferrous Metals:
1. High Carbon Steel: It is often referred to as shear resistant. It is used for manufacturing cutting tools, pliers, drills, punches, and hammerheads.
2. Mild Steel: Mild steel is soft to work with. It is used for manufacturing bolts, nuts, structural work, and non-cutting tools.
3. Cast Iron: Cast iron is made from pig iron. It is wear-resistant. It is used for producing piston rings and cylinder blocks.
4. Wrought Iron: This metal can withstand sudden shock. It is used for making gates, railings, chains, shackles, and couplings. This property is called Toughness and it is opposite to brittleness.
Uses of Non-Ferrous Metals:
1. Zinc: Zinc is used as a coating for steel and for roofing since it is resistant to corrosionCorrosion is defined as a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air. This reaction causes damage and... More.
2. Tin: Tin is used in the production of enamel. Enamel is used to protect metals from corrosion and to protect car bodies.
3. Copper: Copper is used in the production of electrical conductors, switches, transformers, and telecommunications.
Copper is malleable and can also be used for domestic heating systems, soldering-iron bits, and for decoration.
4. Lead: Lead is used for making lead pipes, water pipes, water tanks, in the manufacture of storage batteries, and ammunition.
5. Aluminium: It is light in weight and does not rust. It is used for manufacturing cooking pots/utensils, aircraft parts, corrugated roofs, electrical cables, and aluminium foils.
