The process of preparing an alloy involves melting the primary metal first, then adding and dissolving other elements (metals or non-metals) in definite proportions. The mixture is then cooled to room temperature to form the alloy.

An alloy is a homogeneous mixture composed of two or more metals, or a metal and a non-metal, where the elements are combined in specific proportions to alter the properties of the primary metal.

Alloying iron with nickel and chromium results in the formation of stainless steel, a material known for its hardness and resistance to rust.

Adding a small amount of carbon (about 0.05%) to iron transforms it into a harder and stronger material, making it more suitable for various industrial applications.

Iron is not used in its pure state because it is soft and prone to stretching, especially when hot.
