Copper, zinc, and iron are d-block elements with atomic numbers 29, 30 and 26 respectively. Aluminium is a p-block element with atomic number 13. They are all metals and are fair to good conductors of electricity. They find usage in industrial as well as domestic fields due to their physical and chemical properties. In this article, we will discuss some of the uses of these metals.
Uses of Aluminium
- In packaging industries, for making coils, cans, wrapping materials, etc.
- For daily use items such as utensils, food containers, watches, etc.
- In construction industries, for making doors, windows, wires, and roofing.
- In transport industries, for making cycles, spacecraft, car bodies, aircraft and marine parts.
- As part of alloys, for making coins.
- For making paints, reflective surfaces, and wires.
Uses of Copper
- Being an excellent conductor of electricity, it is extensively used in making electric wires and cables.
- For making industrial tools and machines, in plumbing and roofing.
- For making alloys such as brass and bronze.
- For making circuits and PCBs.
- For making pipes, gutters, vaults, and doors.
- In making musical instruments.
Uses of Zinc
- The most important application of zinc is the hot-dip galvanization. It is the process of immersing iron or steel in molten zinc, and thus coating a layer of zinc on their surface to protect them from corrosion. Galvanised steel is an excellent and cheap substitute for stainless steel.
- For making electrical cells and batteries.
- For making alloys such as brass and German silver.
- Zinc compounds are used for making dyes, paints, anti-dandruff shampoos and diet supplements.
Uses of Iron
- Iron is one of the cheapest, strong and abundant elements on earth, finds a broad range of application.
- It is the major component of the alloy steel which is used for the manufacture of building equipment, industrial tools, machinery, furniture, weapons, etc.
- In the household, it is used everywhere from kitchen appliances to furniture to iron fences.
- Iron is used as a catalyst for commercial production of ammonia by Haber’s process.
- Wrought iron is resistant to rust and can be molded easily. Hence, it is used in the manufacture of armors, chains, bolts and agriculture tools.
- Cast iron has a property of being heated uniformly. It is used for making lasting cookware, toys, pipes, stoves, etc.
- Metallic iron is used for making magnets.
