Zinc

It is mainly used for extending the life of other materials such as steel, plastics and wood through the process of galvanization. In short, it is the process of applying a layer of protective zinc coating on steel to prevent rusting. In Singapore, we use galvanized steel lamp post on our streets and roads because of its excellent resistance to atmospheric corrosion. You can find zinc metal in day to day items like our race medals and window handles and for industrial use as zinc anodes.

Aluminium

This soft but popular metal is another type of widely used metal because of its low density and ability to resist rust. Aluminium is extensively recycled because it cost lesser to recycle it than to extract it from its ores.

Aluminium encompasses so many products ranging from window frames, aluminium foils, cooking pots and to used beverage containers. Aluminium can also be used as a conductor of electricity for electrical wires. However, most of the insulated aluminium wires have no scrap value due to its nature of low value.
