ABSTRACT
The tenn engineering material is used for a material designed, made and used for a practical purpose, e.g. carrying a mechanical load or perhaps providing a path for an electric current. You are surrounded by products involving a wide range of such materials, e.g. the motorcar with its shaped metal exterior surface, an electric cable with its metal core to carry the current and plastic sheath for electric insulation, the mobile phone with its plastic casing; a house with its brick structure and glass windows, a desk made of wood.
