Metal Alloys: Examples, Properties and Uses

An alloy is a metal that is obtained by mixing two or more metals together. Alloys that contain iron are called ferrous alloys, for example, steel. Alloys that do not contain iron are called non-ferrous alloys, examples include brass, duralumin, bronze, etc.

1. Non-Ferrous Alloys:

a. Brass: Brass is an alloy. It is made up of a combination of 65% copper and 25% zinc. It can easily be worked with hand tools. If the copper content is up to 65%, brass can be ductile and can be bent when cold. It resists corrosionCorrosion is defined as a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air. This reaction causes damage and... More. It is therefore used for taps, valves, pipes, screws, etc. It is also used in producing musical instruments and ornaments.

b. Bronze: It is an alloy of copper and tin. It contains about 80% Copper and 20% Tin. It is reddish-brown in colour and has a beautiful appearance. It is used in making sculptures, producing medals, coins, springs, and architectural work.
