Metallurgical & Material Engineering :
The department. of Metallurgical Engineering was established in 1956 with the purpose of imparting excellent training to students who would be able to join several industries as qualified engineers, dealing with the production and processing of metals and alloys including foundries, rolling mills and fabrication shops. The focus of post graduate degree is mainly fixed to train qualified metallurgical engineers for state of art technologies at different Indian metallurgical industries.
