Did you ever wonder why your stainless steel plates never rust even after coming in contact with water and air?  It is because they are alloys. The application of alloys improves the property of metals. Thus, you are surrounded by alloys used in daily life. Usually, it is rare to find metals such as iron, copper, gold, silver, etc. in their pure form.  You will come across their alloys, such as brass, steel, bronze, etc. An alloy is a homogeneous blend of two or more than two metals or a combination of a metal and a nonmetal. Here, we will learn about alloys and their applications in detail.

Application of Alloys

Application of alloys is an indispensable part of our daily life since metals cannot be used in their purest state.  Let us understand the uses of alloys with the help of an example. Iron in its pure form is so soft that you can easily stretch it when hot. However, when you add 0.05% of carbon to iron, it becomes strong and hard. Furthermore, when you mix nickel and chromium with iron, you get an alloy known as stainless steel. Stainless steel is suitable for rough use in the household since it is hard, light-weight, and does not rust. Therefore, uses of alloys hold a high degree of importance in our daily lives.


Uses of Alloy Steel

Steel is the most common yet the most useful metal of all times. There are multiple uses of alloy steel in our daily lives because of its physical and chemical properties. The alloy steel is a composition of carbon steel added to the homogeneous mixture of metals and non-metals.  Alloy steel is further divided into two types – low-alloy and high-alloy. High-alloy steel is a mixture of metals where the alloying element is above 8%.

On the other hand, low-alloy steel contains less than 8% of the alloying element. Elements, such as aluminium, chromium, copper, nickel, cobalt, manganese, silicon, etc. are mixed separately in different proportions to derive the desired constituency of alloy steel.  Each element provides a specific property to the steel. Alloying provides strength, durability, and hardness to steel. 


Alloys and Their Importance

Whatever you see or use, you cannot ignore alloys used in daily life. Pure metals are chemically reactive. Due to the moisture and gases present in the atmosphere, pure metals tend to erode.  However, metals in alloy form are more resistant to corrosion. They make metals more durable and easy to use. They acquire high-tensile strength.

Alloy is prepared by melting the primary metal in liquid form and dissolving another metal or metals in accurate proportion. The mixture is then allowed to cool down and harden.  Such a composition of two or more metals prepares an alloy.  There is a vast list of metal alloys and their uses in our daily lives. Below is the name of daily life alloys and their composition, and uses in a tabular form.

Fun Fact on Uses of Alloys in Daily Life

  1. 22 Karat Gold is an excellent example of alloys used in daily life. The gold ornaments you wear to a wedding are alloys. Twenty-four-carat pure gold is an incredibly soft metal, which can be moulded with fingers easily.  A goldsmith makes 22-carat gold ornaments with a homogeneous mixture of gold and silver, or gold and copper.

  2. The steel plate that you use in your daily life to eat food is environmentally-friendly since 80% more than 80% of the old steel can be recycled into a new one.

  3. When you drink water from a brass jug, you will be free from respiratory diseases.

FAQ (Frequently Asked Questions)

Q2.  What are the Needs and Uses of Alloy Steel in Daily Life?

A2. When carbon steel is alloyed with other elements to improve its mechanical properties, it is called alloy steel. Alloying elements such as copper, aluminium, chromium, manganese, nickel, tungsten, silicon, vanadium, etc. are added to carbon steel to derive desired kinds of alloy steel to suit your need. Low-alloy and high-alloy are obtained from alloying steel. People commonly use low-alloy steel for their physical attributes. Alloy steel is of high-utility in construction of buildings, automobiles, bridges, roads, electronics, pipelines, etc. Furthermore, alloy steels are useful in medical equipment because they are highly-dependable. Alloying steels become resistant to corrosion and oxidation. Moreover, they can withstand high-temperature.
