Chemistry – Metals - Uses of metals | e-Consult

Metals are chosen for various applications based on their unique physical properties. Aluminium is particularly valued for its combination of properties. Here's a breakdown of its uses:

• Aircraft Manufacturing: Aluminium's key advantage is its low density. This is crucial for aircraft as it reduces the overall weight of the plane. Lighter aircraft require less fuel to fly, leading to improved fuel efficiency and reduced emissions. While strong, aluminium is significantly lighter than steel, making it ideal for structural components like wings and fuselage.
• Overhead Electrical Cables: Aluminium is also used in overhead electrical cables due to its low density. This reduces the load on supporting structures (towers). Furthermore, aluminium has good electrical conductivity, allowing electricity to flow efficiently with minimal energy loss.
• Food Containers: Aluminium's resistance to corrosion is a major benefit in food containers. It doesn't readily react with food or the environment, preventing contamination and extending the shelf life of packaged foods. It's also lightweight and easily recyclable.
