July 4 2026 marked 250 years of USA’s independence. In 250 years the USA has become the most prosperous nation in the world. It has created new scientific disciplines—electrical,aeronautical,semiconductor and taken existing classical sciences —thermodynamics ,mechanics as well as material engineering to new heights. It has done this while fighting colonialism, famines,civil unrest, the great depression, 2 world wars and numerous other global shocks any one of which would have been enough to end the strongest of empires. Regardless of what its critics may say, what the USA has achieved is no small feat. It has accomplished what many considered to be impossible several times in the 250 years since it gained freedom. These achievements are most certainly a cause for celebration.

Aluminium is one of the most important industrial materials renowned for being as light as ceramics despite having a metallic character. It possesses high thermal conductivity,excellent reflectivity and electrical conductivity that is higher than steel making it a direct competitor to iron and its alloy systems. Globally the Al market is valued at ~$180B with 72 Million Tonnes of Al produced annually. India is the world's second largest producer at 4.2 M tonnes of annual production and $12 B of market value. Aluminium being important both technologically and economically I was glad to attend the conference organised by Aluminium casters association of India and learn about what new technical and business innovations are being planned for this metal. I was excited to learn that the industry leaders have recognised applications beyond the automotive and packaging sector. Because of its high electrical conductivity one of the most lucrative non automotive applicatio...
