  • Energy needed to produce aluminum - Today in Energy - U.S ...

    Total aluminum sector energy use accounted for over 300 trillion British thermal units in 2006. Primary processing includes processing raw materials and manufacturing aluminum. The subsector secondary processing includes melting scrap. The other two subsectors are downstream products that can be made either from primary or secondary aluminum.

  • What Is Cold Working or Work Hardening? - The Balance

    Bending of sheet metal is another process for cold working, which involves deforming metal over a work axis, thereby creating a change in the metals geometry. In this method, the shape changes, but the volume of the metal remains constant. An example of this bending process is simply bending of steel or aluminum parts to meet the desired curvature.

  • The Process of Anodizing, Explained

    Depending on the end-use application and the anodizing process used, the oxide layer can be expanded greatly. The layer that can be grown on an aluminum part can be more than 100 times as thick as an oxide layer that would naturally exist on an aluminum part that is only exposed to oxygen.

  • Hot-Rolling, Cold-Forming, Extruding and Forging

    Hot-Rolling, Cold-Forming, Extruding and Forging. In general, "rolling" is a process that uses a pair of rolls to form materials. There are two rolling techniques, hot-rolling and coldroll-forming based on the temperature of the metal being used. If the temperature is above the crystallization temperature of metal, the process is called hot ...
