Aluminum Circles and Aluminum Discs Overview
Although "aluminum circle" and "aluminum disc" are commonly referred to as "round aluminum plate, " they have subtle differences in specific situations according to industry standards and applications, (aluminum circle VS. aluminum disc).
What Are Aluminum Circles?
Aluminum Circle refers to a circular aluminum sheet, emphasizing its geometric round shape. It can be flat or semi-processed and is often used as a raw material for further manufacturing.

What Are the Aluminum Discs?
Aluminum Disc also denotes a circular aluminum sheet but sometimes highlights specific processing or application purposes, such as finished products ready for direct manufacturing use.

Production Processes and Technological Innovations
Aluminum circles and discs can be categorized into DC (hot-rolled) and CC (cast-rolled) types based on production processes. DC aluminum circles are ideal for deep-drawing applications like rice cooker liners.CC aluminum circles are more cost-effective and can substitute DC circles in some deep-drawing scenarios.
CC Aluminum Circle vs DC Aluminum Circle
Feature | Cast-Rolled Aluminum Circle | Hot-Rolled Aluminum Circle |
---|---|---|
Raw Material | Cast-rolled coil | Cast-rolled aluminum slab |
Production Process | Processed via cold rolling | Produced through hot rolling |
Surface Quality | Average | Good |
Mechanical Properties | Average | Very good |
Deep-Drawing | Different | Good |
Anodizing Effect | Average | Good |
Applications | Traffic signs, etc. | Cookware, lighting, etc. |
Productivity | High | Average |
Cost-Effectiveness | Higher | Lower |
Surface Treatment Processes
- Anodizing: Produces a 5-35μm oxide film to enhance corrosion resistance.
- Mirror polishing: Achieves a reflectivity of over 86%.
- Embossing: Creates patterns like orange peel or hammer texture.
- Brushed: Circular/Spiral brushing, linear brushing, etc.
- Teflon Coating: Teflon coating on aluminum circles and discs.
- Color Coating: PE, PVDF coating on aluminum circles and discs.
Forming Technologies
- Die Stamping: Suitable for mass production with low costs and high efficiency.
- Conventional Cutting: Employs a circle cutting machine, ideal for large-diameter aluminum circles.
- Laser Cutting: Achieves precision of ±0.1mm for complex shapes (e.g., ventilation holes).
- Spinning: Used for seamless forming of lamp reflectors and gas cylinder bottoms, requiring a material elongation of ≥10%.
