What Are Alloys?

Alloys are metal mixtures with other elements, the precise combination of which is governed by the properties required. In general, alloys are considered metallic in nature, i.e. they have good thermal and electrical conductivity.

Definition

Alloys are combinations of metals or metals and other elements. To confer certain properties to metals, or strengthen some of their present properties, certain other metals/elements can be added to the metals in specific ratios to form alloys. In simpler words, an alloy is a homogeneous mixture of two or more metals or a metal and a nonmetal.

Example

For example, pure aluminium is a relatively soft metal. Pure copper is also quite soft. However, when aluminium is alloyed with copper, the strength of the resulting alloy is far greater than that of its parent metals. Soe other important examples of alloys are listed below

  • Steel
  • Nichrome
  • Bronze
  • Brass
  • Duralumin
  • Solder

Significance

Alloys have a wide variety of uses. The interpretation of alloys actually reduces the material’s price and maintains the metal’s desired properties. The combination of metals improves material properties and offers resistance to oxidation and mechanical strength.

Applications

Listed below are the applications of alloy in daily life

  • Used for many home decorative items and is composed of copper and zinc.
  • The alloy of bronze is used for making statues and medals as well as home decorates.
  • The carbon steel alloy is used for weapon making, while in household items it’s used in high tensile blade making. These are used in grinders, blenders and juicer.
  • The alloy amalgam, used for many medical activities has silver, tin, copper, and zinc with mercury, indium, and palladium.
  • The cookware cutlery and other major appliances like refrigerator and gas stove, surgical instruments contain stainless steel which is mainly composed of carbon, chromium and nickel with iron as the main component.
