Engineering Materials: Properties and Classification

In this article we will discuss about the properties and classification of engineering materials used in industries. Properties of Materials: Material selection should be based mainly upon the properties of material. The designer must decide the properties required of a material for a part under design and then weight the properties of candidate material. There are literally hundreds of properties [...]

Classification of Engineering Materials | Industrial Engineering

Broadly, engineering materials can be classified as: (a) Metallic materials and (b) Non-Metallic materials. Metallic materials could further be classified as: (i) Ferrous metals (consisting of iron and alloys of iron) and (ii) Non-Ferrous materials and alloys. Non-metallic materials include plastics, asbestos, rubber, wood, concrete, ceramics etc. The selection of a material for a particular application is governed by the [...]
