Aluminum Disc

Aluminum circle disc is a circular metal material made of aluminum alloy, with common diameters ranging from 10 to 3000 millimeters, covering multiple alloy series such as 1-series, 3-series, and 5-series. It is mainly used in the fields of electronics, daily chemicals, pharmaceuticals, education, and automotive parts. This product is processed by casting, rolling, cold rolling, and other techniques, featuring corrosion resistance and excellent electrical conductivity. It is widely used in the manufacture of cookware, capacitor housings, traffic signs, and aerospace equipment components.

Aluminum circle disc, also known as aluminum round billet, aluminum gasket, or aluminum blank, refers to circular sheet materials processed from aluminum plates or aluminum coils through stamping, turning, or laser cutting. It is a very common and important basic component in many industrial fields and daily products.

Aluminum discs are used in electronics, daily chemicals, medicine, culture and education, and auto parts. Electrical appliances, thermal insulation, machinery manufacturing, automobiles, aerospace, military industry, molds, construction, printing and other industries. Kitchenware such as non-stick pans, pressure cookers, and hardware such as lampshades, water heater shells, and stretch tanks are among the most widely used aluminum alloy sheet and strip deep-processing products.

Aluminum discs are products of aluminum plates that have been deeply processed. Hot-rolled aluminum discs have the advantages of good heat dissipation, good conductivity, corrosion resistance, light material, and long service life.

Aluminum Circle Disc Surface Finishing Options

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.

• Series 1 Pure Aluminum (e.g., 1060, 1100): Aluminum content ≥99%, featuring high plasticity, corrosion resistance, and electrical conductivity. Suitable for deep drawing, commonly used in cookware and lamp housings. For example, 1060 alloy is suitable for making non-stick pans and lamp shades.
• Series 3 Aluminum-Manganese Alloy (e.g., 3003): Manganese added to improve strength and corrosion resistance, excellent formability, commonly used for pressure vessels, automotive parts, and architectural curtain walls. Surface hardness can be enhanced by anodizing.
• Series 5 Aluminum-Magnesium Alloy (e.g., 5052): Outstanding high strength and fatigue resistance, suitable for automotive structural parts and aerospace applications.

Aluminum Circle and Disc Application Specification Parameter Table

The choice of aluminum alloy discs for different applications is driven by the specific properties required for each use case. Here’s a breakdown of why specific alloys are chosen for the corresponding applications:

What is a good Aluminum Circle and Disc blank?

• 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.
• 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.
• 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.
• 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

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

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

• 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.
• 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.
• 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.
• Packaging customers can choose as per their convenience.

Generally speaking, one package is 2 tons, 1×20′ container is loaded with 18-22 tons, and 1×40′ container is loaded with 20-24 tons.

Aluminum Disc Production Process

• Die Stamping: The most commonly used and most efficient method. Aluminum sheets or coils are rapidly stamped and blanked on a press using molds. Suitable for large-scale production.
• Laser Cutting: Uses a laser cutting machine to cut circular shapes according to programmed paths. Suitable for small batches, multiple varieties, or thicker materials with high precision requirements. Highly flexible with no mold cost.
• Lathe Finishing: CNC lathes are used to machine aluminum rods into discs. Suitable for precision parts requiring extremely high dimensional accuracy, roundness, and flatness.

How to Choose an Aluminum Disc Supplier

• Production Capacity: Confirm whether the supplier has stamping or cutting equipment suitable for your product specifications.
• Material Source: Ensure the source of aluminum is reliable and material quality is stable.
• Quality Control: Check if the supplier has a complete quality inspection system (e.g., dimensional inspection, material reports).
• Sample Confirmation: Always request samples and confirm their quality before mass purchasing.
• After-Sales Service: Choose a supplier who can provide strong technical support and good after-sales service.
