German Scientists have established an alloy with ultra-high-purity of magnesium of exceptionally low corrosion rate– Stainless Magnesium approach, via alloying of pure magnesium (Mg) with a tiny amounts of calcium (Ca) has been reported in Materials Horizons on 24 th November 2020. Mg is found to be the lightest structural metal with various properties like high strength-to-weight ratio, excellent electrochemical characteristics, Young’s modulus similar to human bone with low cost. Mg is widely used in aerospace, electronic, automotive, biomedical and energy-storage applications owing to its high strength, low weight, and excellent electrochemical properties, due to its abundance in the earth’s crust. Particularly, Mg possess light weight than aluminium (Al) and makes attractive from a sustainable perspective. Therefore, replacing of Al with ‘ Stainless Mg ’ in flights and cars will reduce the fuel consumption with free of carbon dioxide emissions. However, its usage is limited and r...
