Question

Why is aluminium a bad conductor?

Answer 1

Aluminium:

• Aluminium $\left(\mathrm{Al}\right)$, also termed aluminium, is a light silvery-white metal in the periodic table's Group $13$.
• Aluminium is the most common nonferrous metal and the most prevalent metallic element in the Earth's crust.

Reason for Aluminium is a bad conductor:

• In comparison to other metals like gold, silver, and copper, aluminium is a poor heat and electricity conductor.
• Aluminium has strong conductivity for electricity and heat because it has three electrons in the free state, but its conductivity is lower than copper since it is less dense.
• Although aluminium is a poor conductor of electricity when compared to copper, it is less expensive, hence it is occasionally utilised in everyday products.
• Another advantage of aluminium over other metals is its low density and great corrosion resistance.
• Aluminium is used in insulated power supply cables because it is less expensive and has a low density.
