Mechanical Engineering Internship

Internship Opportunity at Aluminum Dynamics

Aluminum Dynamics is developing a state-of-the-art, 650,000-tonne low-carbon recycled aluminum flat rolled mill, supported by two satellite recycled aluminum slab centers. The facility will produce a wide range of flat rolled aluminum products while prioritizing sustainability through advanced recycling practices. Our product offering includes value-added finishing lines such as Continuous Annealing and Solution Heat treatment (CASH) lines, continuous coating, and multiple slitting and packaging operations.

This combination of cutting-edge technology and sustainable processes positions Aluminum Dynamics as a leader in delivering high-quality, low-carbon aluminum solutions to meet the growing demands of diverse industries.

This internship is located at the Aluminum Dynamics facility located in Columbus, MS, in the Melt / Cast Department. This internship will take place during Summer 2027.
