WHAT IS METAL? A metal is a chemical element that is a good conductor of both electricity and heat. Metals are malleable and ductile and have lustrous appearance. They have moderate to high physical constants and high tensile strength. Metals are further divided into two main groups - ferrous and non ferrous metals. TYPES OF METAL • FERROUS METAL These are metals which contain iron. They may have small amounts of other metals or other elements added‚ to give the required properties
