Which metal is non-ferrous, lightweight and easy to recycle and used for cans, saucepans, bikes and ladders?

• A. Copper
• B. Brass
• C. Aluminium
• D. Stainless steel

Answer: (C)

Aluminium fits this combination because it is a non-ferrous metal, meaning it contains no iron and doesn’t rust in the same way as steel. It’s very lightweight, which makes it ideal for items you want to carry or handle easily—like cans, bicycles, ladders, and cookware. Its ability to be recycled efficiently without losing quality is a big plus in producing everyday goods, especially cans, which are routinely recycled and re-melted to make new aluminium products.

Copper is non-ferrous but heavier and more expensive, so it isn’t the common choice for cans, ladders, or lightweight bike frames. Brass is an alloy of copper and zinc, not as light or cost-effective for these uses. Stainless steel is ferrous (contains iron) and heavier, so it doesn’t offer the same lightweight advantage.
