Understanding the Elements: The Coordination of Materials, Coatings and Geometry Key To High-Speed Aluminum Machining. Technological developments such as the Makino MAG-Series machines have made tooling vendors rethink the core concepts of their tooling designs. To get the most out of any state-of-the-art machine technology, it is vital to ...
Aluminum building materials are also recycled. Producing secondary aluminum involves cleaning and separating aluminum scrap from other materials and melting it down in a furnace, usually fired by natural gas. Compared to the energy requirements of primary production, secondary production is much less energy intensive.

Recycling aluminum saves more than 90 percent of the energy that would be needed to create a comparable amount of the metal from raw materials. Tossing away an aluminum can wastes as much energy as pouring out half of that can's volume of gasoline. Nearly 75 percent of all aluminum produced is still in use today.
