How are materials classified?

1, from the point of view of use.

Raw materials can be divided into electronic materials, aerospace materials, nuclear materials, building materials, energy materials and biological materials.

2. Analyze physical and chemical properties.

Raw materials can be divided into inorganic materials, organic materials and composite materials, and inorganic materials can be divided into metallic materials and inorganic nonmetallic materials.

3. Analysis from the perspective of development.

Raw materials can be divided into traditional materials and new materials. Traditional materials refer to mature materials that have been mass-produced and widely used in industry, such as cement, steel and other materials, while new materials are a kind of materials with special properties and application prospects. There is no obvious difference between traditional materials and new materials. New materials are developed from traditional materials.

4. Analyze from the performance of the material itself.

Raw materials can be divided into structural materials and functional materials. Structural materials are based on mechanical properties, supplemented by other physical and chemical properties, and are used to manufacture stress components, while functional materials are mainly formed by using the unique physical and chemical properties or biological functions of substances.

5, from the industry to specific analysis.

Can be divided into clothing, building materials, food and beverage, household goods, office culture and education, chemical raw materials, hardware tools, machinery and equipment, rubber and plastic products and instruments and other fields.
