Classification of Materials Metals, Polymers, Ceramics

Materials can be majorly classified in five considerable categories i.e. Metals, Polymers, wood, fabrics and Ceramics. Unlike iron aluminum has a lower melting point of 659 degree centigrade while that of iron is about 1530 degree centigrade. Aluminum can be easily manipulated through machining, casting, drawing and extrusion.
