Mechanical parts are parts used in various machines and facilities such as industrial machines, plants, and automobiles used in factories. The materials used are generally various metals and resins such as iron, stainless steel, and aluminum. These mechanical parts are also called mechanical components, and play a significantly important role in the construction of machines and equipment.

Some mechanical parts are worn out or deteriorated by prolonged use and need to be replaced periodically. Since that, it is called consumable parts.
