**1. Introduction**

Materials are the key stuff of engineering to household applications which creates pursuit for commercialization. The present world is a competitive customer driven one. The need to save our mother Earth, limited primary resources and stringent norms paved the way to use of the newer materials in engineering sectors. Quality, comfort, safety and reliability of product are the major concern of survival of the industries. Product's quality is influenced by its design features, material selection and processing techniques. This emphasised the innovation of newer materials to tailor the needs of ever growing demand product for better engineering properties as well as aesthetics. Materials are playing the most vital part from the past till the current scenario as well as in upcoming future. These are substances out of which anything can be prepared. They have contributed to the development of various fields such as space, communication, transportation, medicine, agriculture and food processing industries. Light weight magnesium and its alloys are the most promising next generation materials. Magnesium and its alloys find unique place in the automotive sector due to better solidification and fluidity, high strength to weight ratio, good damping behaviour and high recycling potential in automotive, aerospace, defence and electronics for better radiation shielding effect as well in biomedical sectors as properties of bone is similar to magnesium.
