Title

As an aluminum circle manufacturer, we produce 0.5mm to 3.0mm 1100 H14 hot-rolled aluminum circles for cookware, lighting, signage, electrical housings, spinning parts, and general industrial forming. Our production is based on controlled hot-rolled aluminum coil, precision leveling, automatic blanking, surface inspection, and export packaging. The objective is consistent thickness, stable temper, clean surface quality, and reliable forming performance in continuous downstream production.

1100 aluminum is a commercially pure aluminum alloy with excellent corrosion resistance, high thermal conductivity, good workability, and a bright mill finish. In H14 temper, the material is strain-hardened to a half-hard condition, providing better shape stability than soft O temper while retaining suitable formability for many shallow drawing, spinning, stamping, and pressing applications. For buyers who require a balance between rigidity and processing performance, 1100 H14 aluminum circles in the 0.5mm to 3.0mm thickness range are a practical and widely used option.

Factory Production Scope

We manufacture aluminum circles from selected hot-rolled 1100 aluminum coil. The coil is slit, leveled, and blanked into round discs according to customer drawings or standard size requirements. Our production line is designed for repeated batch manufacturing, so customers can obtain stable aluminum discs with consistent diameter, flatness, burr control, and surface condition.

The 0.5mm to 3.0mm thickness range covers many common industrial uses. Thinner gauges such as 0.5mm, 0.6mm, and 0.8mm are often selected for light covers, small stamped parts, tags, and electronic components. Medium gauges such as 1.0mm to 2.0mm are widely used for cookware bases, non-stick pans, lamp reflectors, and general forming. Heavier gauges such as 2.5mm and 3.0mm are typically used where higher rigidity, better heat retention, or stronger structural support is required.

For customers comparing pure aluminum grades, our 1000 Series Aluminum circle production includes 1050, 1060, 1070, 1100, and 1200 alloy options. Among them, 1100 is often selected when slightly higher strength than 1050 or 1060 is required while maintaining good corrosion resistance and processability.

Why Use Hot-Rolled 1100 Aluminum Circle

Hot-rolled aluminum circles are produced from hot-rolled plate or coil, followed by cold working and finishing steps. Compared with some cold-rolled only routes, hot-rolled feedstock can offer a more uniform internal structure for certain forming operations, especially where the customer requires stable performance in spinning, pressing, or cookware processing.

The advantages of hot-rolled 1100 H14 aluminum circles include good dimensional stability, uniform mechanical behavior, and reduced risk of cracking when the forming parameters are properly matched. The material is also suitable for surface treatments such as cleaning, anodizing, polishing, painting, and non-stick coating, depending on the end product and pretreatment system.

As a factory, we evaluate coil quality before blanking. Surface scratches, oil stains, severe waves, edge cracks, and lamination defects are controlled during incoming inspection and production monitoring. This helps reduce downstream rejection rates for customers using automatic feeding, hydraulic pressing, or spinning equipment.

Technical Parameters

The following specifications are our regular manufacturing range for 0.5mm to 3.0mm 1100 H14 hot-rolled aluminum circles. Special requirements can be reviewed according to drawings, application, tolerance level, and order volume.

Chemical Composition and Mechanical Reference

1100 aluminum belongs to the commercially pure aluminum series. Its performance comes from high aluminum content, good ductility, and stable corrosion resistance. The values below are for reference and final supply can be arranged according to the standard specified in the purchase contract.

Mechanical properties are affected by thickness, rolling history, temper control, and test method. For engineering projects, we recommend confirming the exact performance requirements before mass production. If the application requires deeper drawing or more severe deformation, we can discuss alternative tempers or related alloy choices. For customers focused specifically on this alloy grade, our 1100 Aluminum Circle production can be configured by thickness, diameter, surface condition, and packing method.

Surface Quality Control

Surface quality is a key factor for aluminum disc users. Cookware manufacturers need clean surfaces for non-stick coating, polishing, or painting. Lighting manufacturers often require a smooth mill finish for reflector processing. Sign and decorative part producers may require uniform color after coating or anodizing. For these reasons, we control surface condition throughout the production route.

Before blanking, the aluminum coil is checked for surface marks, oxidation, heavy oil, edge damage, and wave shape. During blanking, the tooling condition is monitored to reduce burrs and indentation. After blanking, aluminum circles are inspected for diameter, thickness, flatness, edge quality, and visible defects. For orders requiring extra surface protection, paper interleaving or plastic film protection can be discussed according to the final processing method.

A clean surface does not only improve appearance. It also helps reduce coating defects, black spots, adhesion problems, and tool contamination during customer production. This is especially important for aluminum circles used in non-stick cookware, pressure cooker components, pan lids, and lighting products.

Forming and Processing Performance

1100 H14 aluminum circles provide a useful combination of moderate strength and good workability. The half-hard condition supports better handling and shape retention than annealed material. It is suitable for many shallow drawing, spinning, stamping, trimming, and forming operations. In cookware production, the aluminum disc can be pressed or spun into pans, pots, covers, and related components. In lighting production, it can be formed into reflectors, lamp housings, and decorative covers.

Because each customer uses different equipment, mold design, lubrication, forming speed, and annealing route, we do not treat all applications as identical. For simple stamping and shallow drawing, H14 may be used directly. For deeper drawing, customers may require a different temper, intermediate annealing, or modified forming parameters. Our technical team can review the drawing and suggest a practical supply condition based on previous factory production experience.

Typical Applications

0.5mm to 3.0mm 1100 H14 hot-rolled aluminum circles are used in industries where light weight, corrosion resistance, and thermal conductivity are important. Common applications include cookware blanks, frying pans, saucepans, kettles, pressure cooker components, non-stick pan bodies, lamp shades, LED light housings, road signs, nameplates, electronic shells, capacitor cases, and general stamped parts.

For cookware, aluminum provides fast and even heat transfer. 1100 alloy is suitable for many pan and pot components after proper forming and surface treatment. For lighting, the material offers low weight and good reflectivity after suitable finishing. For signage and traffic products, aluminum discs are valued for corrosion resistance, coating compatibility, and outdoor durability after painting or anodizing.

Thickness Selection Guide

The correct thickness depends on the final product structure, forming method, weight target, and mechanical requirement. A 0.5mm aluminum circle is usually chosen for light parts that do not require high load-bearing strength. Gauges from 0.8mm to 1.5mm are common for covers, light cookware, reflectors, and general stamped items. Thicknesses from 2.0mm to 3.0mm are selected when the part requires better rigidity, longer service life, or stronger heat distribution.

Diameter selection is also important. Larger diameters require stricter control of flatness and packaging to prevent deformation during transport. Smaller aluminum discs require consistent stacking and burr control so they can feed smoothly into automatic equipment. As the original manufacturer, we can arrange production according to both metric and inch-based drawings, provided that tolerance, quantity, and packaging requirements are clearly confirmed.

Packaging for Export Orders

Export packaging is designed to protect the aluminum circles during container loading, ocean transport, warehouse handling, and customer unloading. We commonly use moisture-proof paper or plastic film, kraft paper wrapping, wooden pallets, steel or plastic strapping, and protective corner boards. Depending on disc diameter and thickness, vertical or horizontal packaging can be selected.

For large-diameter or thin-gauge aluminum discs, pallet stability and side protection are especially important. For smaller discs, compact stacking can improve handling efficiency and reduce movement during transportation. Each pallet can be labeled with alloy, temper, size, net weight, gross weight, batch number, and customer order reference for traceability.

Quality Assurance and Traceability

Our quality control system covers raw material inspection, in-process measurement, final inspection, and shipment verification. Thickness is measured by micrometer or calibrated gauge. Diameter is checked according to the approved tolerance. Surface quality is inspected under suitable lighting. Edge burr, flatness, and stacking condition are controlled before packaging.

Traceability is maintained through coil number, production batch, inspection record, and packing list. When required, we can provide a mill test certificate showing alloy, temper, chemical composition, and mechanical reference values. For long-term industrial buyers, stable repeat orders are supported by maintaining agreed standards for tolerance, surface finish, and packing method.

Ordering Information

To quote and produce 1100 H14 hot-rolled aluminum circles accurately, we recommend that customers provide alloy, temper, thickness, diameter, quantity, tolerance, application, surface requirement, packaging preference, and destination port. Drawings or sample photos are helpful when the product is used for specific stamping, spinning, or cookware production.

As a factory, our responsibility is to supply aluminum circles that match the agreed technical conditions and support stable downstream processing.
