As a professional manufacturer of aluminium disc (also known as aluminum circle or round aluminium disc), we understand what industrial buyers need: consistent quality, competitive pricing, and fast delivery. Whether you require small 3 aluminum disc blanks for nameplates or large 24 aluminum disc for cookware bottoms, this guide covers everything from technical specifications to value‑added services like aluminum discs with center holes and anodized aluminum discs.

1. What Is an Aluminium Disc?

An aluminium disc is a flat, round blank cut from aluminium sheet or plate. The most common alloy used is 1050 (99.5% pure aluminium), which offers excellent workability, high thermal and electrical conductivity, and strong corrosion resistance. Due to its soft and ductile nature, 1050 aluminium disc is ideal for deep drawing, spinning, stamping, and anodizing.

Other names include aluminium disc plate, round aluminium disc, and aluminum circle. Our factory produces these discs from prime grade hot‑rolled or cold‑rolled coils, ensuring tight tolerances and a smooth surface on both sides.

12″ (305 mm)	1.0 – 4.0	200 – 800 kg
24″ (610 mm)	1.5 – 5.0	800 – 2600 kg

For aluminium discs cut to size outside standard ranges, simply send your drawing – we operate high‑speed blanking presses and laser cutters for precision (±0.1 mm on diameter).

4. Special Features: Center Holes & Anodized Finish

Aluminum discs with center holes

Many applications require a precise center hole: loudspeaker cones, lighting reflectors, rotating dials, or mounting rings. We can punch a center hole (any diameter) during the stamping process, eliminating secondary drilling and reducing your production cost. Tolerances as tight as ±0.05 mm are achievable.

Anodized aluminum discs

Anodized aluminum discs offer a hard, durable, and decorative surface. Anodizing increases corrosion resistance and allows colouring (silver, gold, black, blue, red, etc.). These discs are widely used for glass table bases, nameplates, outdoor signs, and decorative trims. We provide both clear (natural) and coloured anodizing with a minimum order of 2000 pieces per colour.

Other surface treatments available: brushed finish, mirror polished, and PVC film coated to prevent scratches during transport.

5. Main Applications of Aluminium Disc

The unique combination of high purity and formability makes aluminium disc the first choice for many industries.

Cookware & Kitchen Utensils

Pressure cooker bottoms, frying pans, non‑stick pots, and lids are deep‑drawn or spun from aluminium discs. The O‑temper provides excellent elongation (>20%) without cracking.

Furniture – Glass Table Bases

Aluminium disc for glass table is a classic application. The disc acts as the supporting base or decorative cover under a glass top. Glass table aluminium disc is often anodized or brushed to match modern interior design.

Lighting & Reflectors

LED lamp housings, street light reflectors, and downlight covers are stamped from aluminium discs thanks to their high reflectivity and thermal conductivity.

Bicycle Components

While high‑strength alloys are used for frames, aluminium discs are ideal for non‑load parts such as aluminium disc brake rotor covers, aluminium disc wheelset spacers, and aluminium disc valve caps. Some custom builds also use our discs as mounting plates for aluminium disc frameset brackets.

General Metal Parts & Craft

Round aluminium disc blanks serve as raw material for gears, flanges, nameplates, coasters, and hobby projects. We also supply metal discs in copper or brass upon request.

6. Aluminium Disc Price – What to Expect

When buyers search for aluminium disc price, they find a wide range. As a manufacturer, we explain the key factors:

• Base metal cost – LME aluminium price plus alloy premium (1050 has a lower premium than 3xxx or 5xxx).
• Diameter & thickness – Very small discs (e.g., 3″) have slightly higher per‑kg cost due to more punching cycles. Very large discs (24″) require wider coils and bigger presses.
• Quantity – Bulk orders (full 20‑foot container, ≈22‑25 tons) significantly reduce per‑kg price. Trial orders below 1 ton may incur a small setup fee.
• Surface finish & processing – Anodizing, hole punching, polishing, or protective film adds value and cost.
• Packaging & destination – Export to Europe, North America, Middle East, or Southeast Asia affects freight cost.

Current FOB price reference (as of 2026) for standard aluminium disc (1050 alloy, O temper, 1‑2mm thickness, order quantity 5‑10 tons): $2,300 – $2,900 per metric ton. For an exact aluminium disc price based on your size, thickness, and finish, request a quotation using the contact form below.

7. Custom Cutting – Aluminium Discs Cut to Size

Stock discs don‘t always fit your exact product design. We specialize in aluminium discs cut to size with fast turnaround. Advantages include:

• Zero waste – you pay only for the shape you need (diameter, hole pattern, notch, etc.).
• Precision – CNC blanking and laser cutting achieve ±0.1 mm.
• No tooling cost for common sizes – custom diameters may require a simple punching tool (one‑time cost, amortized over order quantity).

Lead time: 15‑20 days for custom diameters; 7‑10 days for standard sizes from stock.

8. Related Consumables – Cutting & Grinding Discs for Aluminium

Although we produce aluminium discs, many of our customers also need tools to cut or finish them. For your convenience, here is a brief overview of aluminium cutting disc and grinding consumables. (Note: we do not manufacture these tools, but we can recommend quality brands or include them in your shipment as a sourcing service.)

• Aluminium cutting disc for angle grinder – Use TCT or diamond blades designed for non‑ferrous metals to avoid clogging. Common sizes: aluminium cutting disc 115mm and 125mm.
• Aluminium grinding disc – For deburring edges after stamping. Zirconia or ceramic grain discs are preferred.
• Aluminium flap disc / aluminium oxide flap disc – For surface blending and finishing. 40‑80 grit removes tool marks effectively.
• Aluminium cutting disc Bunnings – Bunnings is a retail hardware chain. For industrial users, we supply compatible consumables in bulk at factory prices.
• Angle grinder aluminium disc – A general term that includes both cutting and grinding wheels. Choose the correct type for your operation.
• Cutting aluminium disc – This term can refer to the disc being cut (our product) or the cutting tool. For tool inquiries, specify “cutting wheel” to avoid confusion.
• Aluminium disc cutter – Some customers use this term to describe a machine or a blade. We can advise on suitable cutters for our discs.

If you need both raw aluminium disc and the corresponding cutting/grinding discs, contact us for a bundled quotation to save shipping costs.
