Aluminum Circle and Disc classified by surface treatment

Aluminum Circle and Disc are classified according to processing technology

• Hot rolled aluminum disc circle

  Hot rolling involves heating an aluminum billet or ingot to a high temperature and then passing it through rollers to form it into the desired shape. Hot rolled aluminum disks are commonly used in applications requiring high strength and formability. Hot-rolled aluminum discs have the characteristics of good electrical conductivity, uniform oxidation color, flawless surface, and easy long-term use.

• Cold Rolled Aluminum Circle

  Cold rolling is a process in which aluminum sheet or strip is passed through rollers at room temperature to reduce its thickness and improve its surface finish. Cold rolled aluminum rounds are typically used in applications where precise dimensions, surface quality and flatness are critical. They are commonly used in electronics, signage and construction applications, and cold rolled aluminum sheets do not oxidize well.

• Aluminum disc circle for deep drawing

  Deep drawing is a manufacturing process that uses punches and dies to form sheet metal into the desired shape. Aluminum disks or circles designed specifically for deep drawing have properties suitable for this process, such as high ductility and formability. These discs are often used to produce cookware, auto parts, and other products that require complex shapes.

• Aluminum disc circle for spinning

  Spinning involves spinning an aluminum disc or circle at high speed while forming it relative to a mandrel or forming tool. Aluminum disks designed for spinning typically have good ductility and surface finish that can withstand the spinning process without cracking or deformation. They are commonly used in the production of lampshades, pans and other products.

Aluminum Circle and Disc by application

Aluminum disc circle for traffic sign

When it comes to traffic signs, aluminum discs are often used as the base material for making reflective traffic signs. The circles are often coated with reflective material to ensure visibility and safety on the road, and aluminum's durability and corrosion resistance make it ideal for outdoor applications such as traffic signs.

Aluminum disc circle for cookware

In cookware manufacturing, aluminum discs are used as the primary material for the bottoms or bodies of pots, pans, and other cookware due to their excellent thermal conductivity. These circles are usually stamped or pressed into the desired shape and size before further processing such as anodizing, coating or finishing.

Aluminum disc circle for lighting

Aluminum discs play a vital role in the production of lighting fixtures, especially LED lights. The circles act as heat sinks, ensuring optimal performance and longevity of the lighting system. Aluminum's thermal conductivity makes it an effective material as it helps transfer heat away from the light source quickly.

What is a good Aluminum Circle and Disc blank?

• 1. Surface quality: High-quality aluminum wafers have no defects such as deformation, scratches, cracks or yellow spots. The surface color is uniform and there is no color difference.
• 2. Chemical composition: The chemical composition should comply with relevant standards and can be detected by a professional spectrum analyzer and compared with standards such as GB/T3880-2012 or ASTM B209. Ensure that various chemical elements are within the scope of standard requirements.
• 3. Mechanical properties: Test the tensile strength and mechanical properties of the aluminum circle through a tensile testing machine to ensure that it meets the standard requirements. This reduces breakage during the stamping and spinning processes and avoids wasting time and material costs.
• 4. Particle size detection: The control of grain size can vary according to the manufacturer's requirements. Most factories control the grain size above level two, while some large factories require level one. This helps improve the yield during aluminum disc production and ensures product quality.

Haomei Aluminum Circle and Disc Quality Assurance

• 1. Wide range of size selection.
• 2. Excellent drawing and spinning quality.
• 3. Excellent surface quality, clean, smooth and scratch-free.
• 4. The cutting edges are neat and burr-free.
• 5. The packaging is well protected.

What quality problems may you encounter during use of Aluminum Circle and Disc?

• 1. Spin cracks: During the spinning or drawing process, aluminum discs may have cracks or edge cracks due to sand, impurities or metal embedding. These cracks not only affect the appearance and quality of the product, but also lead to waste during the production process.
• 2. Surface orange peel problem: The surface of some finished pots may not be smooth enough and needs to be polished. This is usually due to the uneven grain size of the aluminum flakes or incomplete processing of the material from the beginning to the end during the production of aluminum discs, which affects the appearance quality of the product.
• 3. Surface oxidation: Although aluminum discs have good anti-rust properties, if they are corroded by rain or moisture during storage or transportation, the surface of the aluminum discs is prone to oxidation. This affects the aesthetics and longevity of the product. Therefore, the packaging must be tight and enough desiccant must be added to prevent the aluminum discs from getting wet.

Aluminum Circle and Disc Packaging and Transportation Precautions

• Can be covered with plastic film and kraft paper according to customer needs.
• Use wooden boxes or wooden pallets to protect products from damage during transportation.
