Alloys and extraction of metals

Metal alloys and extraction of metals. METAL ALLOYS. •By mixing a metal with other metals or some non metals, we can change its properties. This process is called alloying and the resulting metal is an alloy. •For example pure gold (24 carat) is a relatively soft element and is easily deformed. The alloy 18 carat gold is used in jewellery.
