Alcoa unveils major advance in aluminum manufacturing technology

Alcoa’s Micromill has a much smaller footprint than conventional direct casting technology, and produces automotive aluminum alloys with 40% greater formability and 30% greater strength.

Alcoa has developed new manufacturing technology—the Micromill—that will produce what the company says is the most advanced aluminum sheet on the market. The Micromill will enable the next-generation of automotive aluminum products, and equip Alcoa to capture growing demand from automakers for lighter-weight, yet durable and formable materials.
