Type of Aluminium Alloy 6063 Circles

6063 Aluminum Circles can be produced through different processes, resulting in hot-rolled discs and cold-rolled discs.

Aluminium 6063 Hot Rolled Circles

  • Production Process: Hot rolling involves heating the aluminum alloy ingot or billet to a high temperature and then passing it through a series of rollers to form the desired shape.
  • Properties: Hot rolled circles typically have a slightly rough surface finish due to the nature of the hot rolling process. The material may have a more relaxed tolerance compared to cold rolled circles.
  • Applications: Hot rolled circles are often used in applications where surface finish requirements are less stringent, and the mechanical properties of the material are critical.

Aluminium 6063 Cold Rolled Circles

  • Production Process: Cold rolling involves passing the hot rolled material through a set of rollers at room temperature or slightly below. This process imparts a smoother surface finish and can improve dimensional accuracy.
  • Properties: Cold rolled circles tend to have a smoother surface finish compared to hot rolled circles. The material may also exhibit improved dimensional accuracy and tighter tolerances.
  • Applications: Cold rolled circles are commonly used in applications where a smooth surface finish and precise dimensions are essential, such as in industries where appearance and aesthetics matter.

The choice between hot rolled and cold rolled circles depends on the specific requirements of the application. Each process offers distinct advantages, and the selection may be based on factors such as the desired surface finish, dimensional accuracy, and the mechanical properties needed for the final product.
