  2. Aluminium recycling - Wikipedia

    en.wikipedia.org/wiki/Aluminium_recycling

    Aluminium recycling is the process in which secondary commercial aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium. [1] It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al 2 O 3) refined from raw bauxite by ...

  3. Foundry - Wikipedia

    en.wikipedia.org/wiki/Foundry

    Melting metal in a crucible for casting A metal die casting robot in an industrial foundry. Melting is performed in a furnace. Virgin material, external scrap, internal scrap, and alloying elements are used to charge the furnace. Virgin material refers to commercially pure forms of the primary metal used to form a particular alloy.

  4. Permanent mold casting - Wikipedia

    en.wikipedia.org/wiki/Permanent_mold_casting

    Permanent mold casting. Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces

    Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold. However, gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces hollow castings.

    Recrystallization temperature is typically 0.3–0.4 times the melting point for pure metals and 0.5 times for alloys. ... and strain in the plastic deformation ...

  7. Aluminium alloy inclusions - Wikipedia

    en.wikipedia.org/wiki/Aluminium_alloy_inclusions

    Liquid metal is cast into a mold containing notches. Once solidified, the resulting bar is bent to expose a fracture surface. The visual observation of inclusions on the fracture is used to determine a K-value for the melt and compared to a preset standard.

  9. Ladle (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Ladle_(metallurgy)

    Casting ladle: a ladle used to pour molten metal into moulds to produce the casting. Transfer ladle: a ladle used to transfer a large amount of molten metal from one process to another. Typically a transfer ladle will be used to transfer molten metal from a primary melting furnace to either a holding furnace or an auto-pour unit.
