Question

What are the uses of alloys in daily life and how are alloys made?

Answer 1

Answer:

Explanation:make medals and jewelleries etc

Answer 2

Answer:

• We see alloys being used in jewelry, utensils, tools etc. The coils in electrical appliances like electric iron, toasters etc are also made of alloys due to their high melting point compared to its constituent metals. Stainless steel cook wares that we use in the kitchen are an alloy of iron, carbon, chromium and nickel. The combination of these metals increases the corrosion resistance of stainless steel.
• Gold jewels that we possess are alloys too. 100% pure gold (24 Karat) cannot be used to make jewels. But gold alloyed with elements like copper, zinc, cobalt, silver etc (18Karat) are only used to make jewels. Bronze utensils or objects are alloys of copper and tin while brass utensils are alloy of copper and zinc.

Alloys are metals combined with other substances in order to make them better in some way. While some people assume the term ‘alloys’ means a mixture of metals, the reality is that alloys are materials made up of at least two different chemical elements, one of which is a metal. For instance, cast iron is an alloy made up of iron (a metal) mixed with carbon (a nonmetal).
