CC DC Aluminum Circle
Hot-rolled (DC) and cold-rolled (CC) aluminum discs are the two mainstream aluminum circle products, suited to different applications due to differences in production processes and performance.
DC aluminum discs focus on high-end deep-drawing demands, employing a high-temperature rolling process. Their surface grain is finer, possessing excellent ductility and mechanical properties, making them less prone to cracking during deep drawing and capable of meeting the processing requirements of complex shapes.
Due to higher process complexity, material loss, and energy consumption, the DC aluminum circle price is relatively high, making it suitable for high-end applications with stringent requirements for forming precision and surface quality.
CC aluminum discs are produced at room temperature through multiple passes on a cold rolling mill. Their deep-drawing performance has significantly improved, enabling deeper stamping processes.
In applications where customer requirements for product precision and surface quality are not high, they can effectively replace hot-rolled aluminum discs. They also feature a simpler production process, precise dimensional tolerance control, and a more cost-effective approach, offering outstanding performance at a competitive price.

FAQ
1. What do DC and CC mean in aluminium circles?
DC = Direct Chill cast aluminium sheet/coil, typically offering better deep-drawing performance and more stable quality.
CC = Continuous Cast aluminium sheet/coil, generally more economical and suitable for common spinning or shallow-drawing applications.
2.What are aluminium circles used for?
Aluminium circles are widely used for cookware such as frying pans, pots, pressure cookers, rice cookers, pizza pans, and baking trays. They are also used for lighting reflectors, traffic signs, and industrial components.
3. Which alloy grades are commonly available?
Common grades include 1050, 1060, 1070, 1100, 3003, and 5052.
1xxx series: high purity, excellent forming and thermal conductivity
3003: improved strength and corrosion resistance
5052: higher strength and better corrosion resistance
4. Which is better for cookware: DC or CC aluminium circles?
DC circles are usually preferred for high-quality deep-drawn cookware because of their more uniform grain structure and forming behavior. CC circles are often selected for cost-sensitive products or spinning applications.
5. What information is needed when ordering aluminium circles?
Buyers should specify:
Alloy grade
DC or CC material
Temper
Diameter
Thickness
Surface/finish requirement
Application, such as deep drawing or spinning
Quantity and packaging requirements
