The molten aluminium is then poured into molds to form ingots or slabs. These ingots are the starting material for subsequent processing steps.
3. Rolling
The ingots are hot rolled or cold rolled into sheets, plates, or coils. Hot rolling involves passing the ingots through heated rollers, while cold rolling is done at room temperature. Rolling reduces the thickness of the material and improves its strength and hardness.
4. Heat Treatment
After rolling, the Aluminium 1060 is heat treated to enhance its properties. This can involve annealing, which softens the material by heating it and then slowly cooling it, or hardening, which increases its strength by heating it and then rapidly cooling it.
