How to distinguish traditional materials from new materials?

Traditional materials refer to those materials that are mature, mass-produced and widely used in industry, such as steel, cement and plastics. This kind of material is also called basic material because of its large quantity, high output value and wide coverage, and it is the foundation of many pillar industries. Advanced materials refer to those materials that are developing and have excellent properties and application prospects. There is no clear boundary between new materials and traditional materials. Traditional materials have become new materials by adopting new technologies to improve their technical content, performance and added value. After long-term production and application, new materials have become traditional materials. Traditional materials are the basis of developing new materials and high technology, and new materials can often promote the further development of traditional materials.
