Material is anything made of matter, constituted of one or more substances. Wood, cement, air, water and any other matter are all examples of materials. Sometimes the term "material" is used more narrowly to refer to substances or components with certain physical properties that are used as inputs to production or manufacturing. In this sense, materials are the parts required to make something else, from buildings and art to airplanes and computers.In chemical reactions specific materials are defined as reagents.
The study of materials and their properties is known as Materials science
Material is also used to refer to a group of ideas, facts, information or data, that may provide the basis for, or are part of some piece of work.
It is of great importance to certify materials in order to ensure their compliance with international and regional directives and regulations across the world.
Raw materials and processing
A material can be anything: a finished product in its own right or an unprocessed raw material. Raw materials are first harvested from the source and divided into a form that can be easily transported and stored, then processed to produce semi-finished materials. These can be input into a new cycle of production and finishing processes to create finished materials, ready for distribution, construction, and consumption.
Some examples of raw materials
An example of a raw material is cotton, which is harvested from plants. Cotton can be processed into rope (also considered a raw material), which can then be woven into cloth, a semi-finished material. Cutting and sewing the fabric turns it into a garment, which is a finished product.
Steel-making is another example – raw materials in the form of ore are mined, refined and processed into steel, a semi-finished material. Steel is then used as an input in many other industries to make finished products.
