Overview of Small-Size Aluminum Circles

Small-size aluminum circles typically refer to circular aluminum blanks with diameters ranging from 50 mm to 400 mm. Depending on their applications, they can undergo stretching, stamping, spinning, trimming, and other processing operations. Their thickness generally ranges from 0.5 mm to 6.0 mm. HAOMEI Aluminum can provide customized sizes, tolerances, and surface finishes, including bright, brushed, anodized, or coated surfaces according to customer requirements.

Typical Diameter Ranges and Processing Methods

Introduction to Aluminum Discs / Blanks

In modern industrial production, small-size aluminum discs are key raw materials for hardware stamping, lighting manufacturing, and cookware production. Among them, the 1060, 1070, and 1100 alloys are widely used due to their excellent properties and versatility.

1060 Aluminum Circle

• Composition: Minimum 99.6% aluminum, typical industrial pure aluminum.

• Features: Excellent electrical and thermal conductivity; good corrosion resistance and formability.

• Applications: Widely used in lighting industry for lampshades, reflectors, and decorative lighting.

1070 Aluminum Circle

• Composition: Minimum 99.7% aluminum, higher purity.

• Features: Outstanding conductivity, thermal performance, and high reflectivity.

• Applications: Commonly used for pots, frying pans, pressure cookers, and other cookware, as well as signage and heat sinks.

1100 Aluminum Circle

• Composition: Minimum 99.0% aluminum with small amounts of Fe and Si, offering higher strength than 1060.

• Features: Excellent corrosion resistance and high ductility; suitable for deep drawing and spinning.

• Applications: Used in cookware, pans, bottle caps, signage, oil/water pot lids, and other light industrial components.

Specifications of Small Aluminum Blanks

Advantages of Small Aluminum Discs

1. Excellent formability: 1000 series pure aluminum discs have high ductility, suitable for stamping and deep drawing without cracking.

2. Environmentally safe and non-toxic: Free of heavy metals; meets food-grade and pharmaceutical packaging standards.

3. Cost-effective: More competitive in price compared to 3000 or 5000 series aluminum.

4. Attractive surface finish: Supports mirror, anodized, electrophoretic, or coated finishing.

5. Good thermal and electrical conductivity: Ideal for electrical components, lampshades, and reflectors.

Applications of Small Aluminum Discs

Cookware and Kitchenware Manufacturing

Aluminum discs are widely used for pots, pans, and cooking utensils. 1060-H0 ultra-soft aluminum discs, with low hardness, are ideal for lampshades, containers, and deep-drawn cookware. 1070 aluminum discs are bright and formable, suitable for spun cookware and induction cookware components. These discs often undergo polishing, sandblasting, anodizing, enameling, or coating after forming.

Lighting and Lamp Manufacturing

Aluminum discs are used in lampshades, lamp bases, and reflectors. 1060-H18 hard-temper aluminum is ideal for punching without burrs and is widely used in downlights, laminated lamps, and streetlights, leveraging aluminum’s reflective properties and formability.

Signage and Construction Materials

Traffic signs and advertising panels are another important application. 1060-H14/H24 semi-hard aluminum discs provide excellent strength and bending performance, making them ideal for signs, nameplates, and decorative panels. In construction, aluminum discs can be used in curtain walls, ceilings, and thermal insulation, maximizing durability and aesthetics.

Electronics, Electrical, and Industrial Components

1060 aluminum has excellent thermal and electrical conductivity, suitable for electronics, transformers, and heat sinks. In projects replacing copper with aluminum, 1060 aluminum is often the material of choice. 1070 aluminum is suitable for gaskets, capacitor foils, and other electronic components, demonstrating pure aluminum’s versatility in electronics.

Quality Control for Aluminum Discs

• Dimensional accuracy: Strict tolerance control for diameter and thickness.

• Surface quality: Free of scratches, oil stains, and oxidation spots to ensure excellent polishing and anodizing results.

• Mechanical properties: Yield strength, tensile strength, and elongation are tested to meet forming requirements.
