Metals and Alloys For PSC

Metals and Alloys

This post lists some of the most significant metals and alloys that job aspirants must study for competitive GK examinations these days. Some of the alloys in the table below, such as brass and bronze, were often asked in previous year Kerala PSC question papers.

Metals, Alloys and their Uses

An alloy is a combination of metal and two or more other elements, which might be metallic or nonmetallic in nature. Some of these alloys, such as gold and silver, exist naturally, but the great majority are man-made.

Pure metals that stand-alone may be ineffective when compared to alloys.

Pure gold, for example, is excessively soft and malleable and ductile. Imagine crafting a ring out of pure gold; it would easily slide between our fingers, therefore jewellery makers combine it with silver or copper to strengthen the metal's endurance and hardness.

Thus, gold offers colour and corrosion resistance, while the other metals add strength.
