Aluminum circles are one of the most widely used semi-finished aluminum products. They serve as the starting material for a diverse range of end products, from the cookware in your kitchen to the traffic signs on highways and the lamp shades in buildings.<\/p>\n\n\n\n

As a simple deep-processing aluminum product, aluminum circles are typically produced in O temper (soft annealed condition). This ensures optimal performance during subsequent deep drawing and spinning operations. <\/p>\n\n\n\n

We supply aluminum circles in a comprehensive range of specifications, covering various alloys, diameters, and thicknesses to meet the needs of different manufacturing processes.<\/p>\n\n\n\n

Diameter Range:<\/strong> 30 mm to 1800 mm<\/p>\n\n\n\n

Production Methods<\/h3>\n\n\n\n

Aluminum circles can be produced using two main methods:<\/p>\n\n\n\n

Method<\/strong><\/th>Description<\/strong><\/th>Features<\/strong><\/th><\/tr><\/thead>
Circular Cutting<\/strong><\/td>Uses a circle-cutting machine (compass cutter)<\/td>Suitable for very large sizes (\u22651800mm); edges can be sharp and not perfectly round; may pose handling challenges<\/td><\/tr>
Dies Cutting<\/strong><\/td>Uses a stamping press with a modular die<\/td>Produces round, smooth edges; no sharp burrs; better surface finish; suitable for automated production lines <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

For industrial-scale production, fully automated blanking lines can achieve production speeds of 40-55 pieces per minute, with material utilization rates reaching 80% or more. <\/p>\n\n\n\n

CC vs. DC: Understanding the Difference<\/h3>\n\n\n\n

Aluminum circles are manufactured from either Continuous Casting (CC) or Direct Chill (DC) rolled coils. The choice between them has a significant impact on deep drawing performance.<\/p>\n\n\n\n
