As a leading global supplier of high-quality non-ferrous metals, we offer premium Aluminum Disc and circle blank solutions. These blanks meet the strict demands of modern industrial manufacturing. Our production capabilities cover a broad thickness range from 0.3mm to 10mm. We provide global procurement managers with highly precise metal shapes. These are ideal for stamping, deep drawing, and surface finishing. Do you require high-volume raw blanks or custom pre-treated discs? We leverage long-term partnerships with leading Chinese processing factories to deliver consistent quality. This hybrid model combines large-scale industrial output with custom processing. Ultimately, it streamlines your supply chain and lowers secondary production costs.
Beyond basic stamping, we provide comprehensive custom fabrication and finishing options. These services transform raw circles into ready-to-use manufacturing components. Our complete processing approach saves buyers time. It also lowers total production costs by eliminating the need for third-party finishers.
Our surface treatment capabilities let us supply custom-finished circles with specialized coatings. Mechanical polishing creates reflector-grade surfaces ideal for architectural lighting. Meanwhile, custom anodizing adds a protective oxide layer. This enhances corrosion resistance and introduces vibrant color options. We also offer precise chemical etching. This creates matte surfaces or unique textures valued in premium cookware and lighting fixtures.
To meet exact specifications, we utilize advanced mechanical processing tools. These include precision punching, bending, pressing, and wire-cutting. Our tooling ensures every Aluminum Disc features smooth, burr-free edges. It also guarantees flat dimensional tolerances. This precision is critical for automated secondary manufacturing lines. It prevents feed jams and ensures perfect alignment during spinning or deep-drawing.
Selecting the right material composition and hardness is essential. It ensures the desired yield strength and elongation in your final product. Below is an overview of our standard specification range for custom aluminum circles.
| Alloy Series | Common Grades | Thickness Range (mm) | Diameter Range (mm) | Key Tempers | Primary Applications |
|---|---|---|---|---|---|
| 1000 Series (Pure) | 1050, 1060, 1070, 1100 | 0.3 - 10.0 | 80 - 1250 | O, H12, H14, H18, H24 | Spinning cookware, lighting reflectors, decorative plates |
| 3000 Series (Mn Alloy) | 3003 | 0.5 - 8.0 | 100 - 1200 | O, H14, H24 | Deep-drawn pots, pressure cookers, non-stick pans |
| 5000 Series (Mg Alloy) | 5052 | 1.0 - 10.0 | 150 - 1000 | O, H32, H34 | Marine components, high-strength signage, industrial parts |
We supply diverse chemical compositions to match specific industrial uses. The 1000-series alloys, including 1050 and 1100, offer pure aluminum options. They provide exceptional electrical conductivity and maximum formability. This makes them highly cost-effective for simple spinning applications. For deep-drawing requirements, our 3003 alloy is the industry benchmark. It provides superior mechanical strength and elongation due to its manganese content. For demanding marine applications, our 5052 magnesium-aluminum alloy delivers excellent corrosion resistance.
Controlling temper is vital for managing ductility and tear resistance during fabrication. We offer fully annealed O-temper aluminum circles. These soft blanks are perfect for extreme deep-drawing and complex metal spinning. For applications requiring greater structural rigidity, we supply work-hardened tempers. Options like H14 or H24 strike the perfect balance between yield strength and formability.
Our products are engineered to excel in distinct commercial environments. We tailor the alloy chemistry, grain size, and mechanical properties. This ensures our circle blanks perform seamlessly under intense manufacturing pressures.
For cookware manufacturers, we produce specialized deep-drawing grade circles. These blanks prevent the "orange peel" effect and minimize wall thinning during pressing. They are ideal for manufacturing non-stick pans, rice cookers, and boiling pots. Our 3003 and 1050 alloys feature a highly controlled grain structure. This guarantees a smooth surface finish that readily accepts non-stick or ceramic coatings.
In the lighting industry, reflectivity and surface purity are paramount. Our high-purity reflector-grade Aluminum Disc blanks readily accept advanced mechanical polishing and anodizing. These discs deliver outstanding specular reflection. They are the preferred choice for recessed commercial lighting, streetlights, and architectural reflectors.
Heavy-gauge circular blanks are widely used for outdoor traffic signs and road indicators. We supply thick, high-strength 5052 and 3003 circles. They feature exceptional wind-load resistance and outdoor durability. We deliver these circles with precise flat tolerances and corrosion-resistant surfaces. This ensures they withstand harsh weather conditions for decades.
As a reliable supply chain partner, we understand that consistency is critical for international buyers. We apply rigorous quality control measures at every production stage. This spans from raw material sourcing through final packing and export logistics.
All our non-ferrous products comply with international standards like ROHS and REACH. To guarantee absolute material integrity, we coordinate third-party pre-shipment inspections. We work with trusted organizations like SGS and Bureau Veritas (BV). These assessments verify exact chemical composition, dimensional tolerances, and surface quality before cargo leaves the port.
Our core strength lies in our extensive supply network. We maintain long-term partnerships with leading Chinese state-owned and specialized metal processing factories. This allows us to offer flexible, large-scale procurement services with reliable lead times. Additionally, we provide supportive customer services like joint product development. We are also happy to conduct comprehensive factory visits or quality inspections on your behalf.
Contact us today to discuss your production requirements. As your trusted non-ferrous metal supplier, we are ready to deliver high-performance Aluminum Disc solutions. We customize every order to perfectly match your design drawings and technical specifications.
What is the typical lead time for custom-anodized or polished aluminum discs?
Lead times vary based on processing complexity and order volume. Standard custom-finished orders are typically processed and ready for shipment within 20 to 30 days. We also offer expedited processing through our factory network for urgent requirements.
Can you provide third-party test reports before shipping the aluminum circles?
Yes, we fully support third-party pre-shipment testing. We can coordinate certification through SGS, BV, or other accredited bodies. This verifies material grade, thickness, and ROHS compliance before delivery.
Which alloy is best suited for deep-drawing cookware products?
Aluminum alloy 3003 is the industry standard for deep-drawing cookware. It offers excellent formability, high elongation, and superior strength compared to 1000-series pure aluminum. For basic spinning applications, pure aluminum alloys like 1050 are highly cost-effective options.
What are your maximum and minimum size capabilities for aluminum circle blanks?
We offer custom-punched and stamped aluminum circles in thicknesses ranging from 0.3mm to 10.0mm. Our available diameters span from 80mm up to 1250mm. This easily accommodates both thin-gauge crafts and heavy-gauge industrial plates.
