Aluminum circle (also called aluminum disc or wafer) is a processed product made from aluminum sheets or coils through cutting and blanking. With properties such as excellent heat dissipation, electrical conductivity, corrosion resistance, light weight, and long service life, aluminum discs are widely favored for cookware, appliances, lighting fixtures, and road traffic signs.
YUQI Metal provides both CC (Cold Rolled) and DC (Hot Rolled / Deep Drawn) aluminum circles, ensuring reliable performance for various forming processes including deep drawing, spinning, stamping, and anodizing.
High thermal conductivity – excellent heat dissipation for cookware and appliances.
Lightweight & durable – reduces overall weight while maintaining strength.
Good corrosion resistance – natural oxide film plus optional surface treatment.
Excellent processability – suitable for deep drawing, spinning, stamping.
Wide alloy selection – 1000 / 3000 / 5000 / 8000 series available.
Custom sizes – diameter, thickness, and temper can be tailored to customer needs.
Strict QC & certification – every disc undergoes inspection for thickness, diameter, and surface.
✅ Raw Material → Melting → Casting → Sawing
✅ Scalping → Homogenizing → Hot Rolling → Tandem Mill
✅ Cold Rolling → Slitting → Blanking (Circle Cutting)
✅ Annealing → Packing → Inspection → Delivery
This process ensures smooth edges, consistent thickness, accurate diameters, and excellent surface quality suitable for further finishing (anodizing, coating, polishing).
1. Raw Material: High-purity aluminum ingots are carefully selected to guarantee excellent formability, conductivity, and corrosion resistance.
2. Melting: The aluminum ingots are melted in a high-temperature furnace to remove impurities and ensure a uniform chemical composition.
3. Casting: The molten aluminum is cast into solid slabs or billets, which serve as the base material for rolling.
4. Sawing: Cast slabs are cut into the required dimensions to prepare them for further rolling and processing.
5. Scalping: The surface layer of the slab is machined off to remove defects and ensure a smooth, uniform surface.
6. Homogenizing: Heat treatment is applied to the slabs to improve internal structure, relieve stress, and enhance mechanical properties.
7. Hot Rolling: The homogenized slabs are hot rolled into thinner plates, improving their mechanical strength and elongation.
8. Tandem Mill Rolling: Continuous rolling is performed to further reduce thickness and improve flatness and surface quality.
9. Cold Rolling: After hot rolling, cold rolling is applied to achieve precise thickness control, improved surface finish, and higher strength.
10. Slitting: The rolled aluminum sheets are slit into narrower strips to meet customer requirements and prepare for circle blanking.
11. Blanking (Circle Cutting): Round discs are punched or cut out of the aluminum sheets with high precision, ensuring smooth edges and accurate diameters.
12. Annealing: Heat treatment (annealing) is applied to restore ductility and ensure excellent deep-drawing performance, critical for cookware and lighting applications.
13. Packing: Finished aluminum circles are tightly packed with moisture-proof materials and strapped securely on pallets to ensure safe transportation.
14. Inspection: Every batch undergoes strict quality inspection for thickness, diameter, surface finish, tolerance, and mechanical properties.
15. Delivery: After inspection and certification, the final products are delivered to customers worldwide.
