The machine elements should be made of such a material which has properties suitable for the conditions of operation. In addition to this a design engineer must be familiar with the effects which the manufacturing processes and heat treatment have on the properties of the materials. In this chapter we shall discuss the commonly used engineering materials and their properties in Machine Design. 2.2 Classification of Engineering Materials The engineering materials are mainly classified as 1. Metals and their alloys such as iron steel copper aluminium etc. 2. Non-metals such as glass rubber plastic etc. The metals may be further classified as a Ferrous metals and b Non-ferrous metals. 16 CONTENTS Engineering Materials and their Properties 17 The ferrous metals are those which have the iron as their main constituent such as cast iron wrought iron and steel. The non-ferrous metals are those which have a metal other than iron as their main constituent .
