Transcript of How is it made?
Finishing process List the 4 steps in the Bayer refining process. Smelting, which separates the aluminum-oxygen compound (alumina) produced by the Bayer process, is the next step in extracting pure, metallic aluminum from bauxite. What happens during the Smelting process? This is accomplished in a rolling mill, where the material is passed several times through metal rolls called work rolls. As the sheets (or webs) of aluminum pass through the rolls, they are squeezed thinner and extruded through the gap between the rolls. How is aluminum foil rolled? It can also be cut, formed into any shape, printed, embossed, slit into strips, sheeted, etched, and anodized. List 6 ways aluminum can be finished ? Other important properties are thickness and tensile strength.
Temperature and time
What are the important quality control properties ? manufacturers are increasing their efforts in the recycling area and already has the advantage of being light and small, which helps reduce its contribution to the solid waste stream. It also uses less energy.
Name two ways aluminum is environmentally friendly?
