Aluminum circle plate is one of the most widely sourced aluminum products in global manufacturing. It is used in cookware, lighting, road signs, and dozens of industrial applications. Whether you need a standard round aluminum plate for spinning, stamping, or deep drawing, this guide covers everything: alloys, specifications, sizes, pricing, and how to choose a reliable supplier.

1. What Is an Aluminum Circle Plate?

An aluminum circle plate is a flat, round disk cut or rolled from aluminum sheet or strip. It is also called a round aluminum plate, aluminum disc, or aluminum plate circular. The product is produced by punching or slitting continuous aluminum coil into precise circular blanks.

The terms “aluminum circle” and “aluminum disc” are used interchangeably in the B2B market. Some buyers also search for aluminum circle ring or aluminum discs with center holes — these are specialized variants with a pre-punched hole in the center, used in pulleys, flanges, and speaker grilles.

Our factory produces aluminum circle plates to custom diameters, thicknesses, and alloy grades. We supply both standard round discs and customized shapes, including aluminum circle ring and hole-punched variants.

2. Common Alloys and Tempers for Aluminum Circle Plate

The alloy you choose determines the circle’s formability, strength, corrosion resistance, and anodizing quality. The table below covers the most widely ordered grades:

Alloy	Temper	Key Property	Typical Application
1050	O / H14 / H18	High purity, excellent formability	Cookware, kitchen utensils, spinning
1060	O / H14	Excellent conductivity & ductility	Traffic signs, cookware, reflectors
1100	O / H14	Good corrosion resistance, soft	Cookware, deep drawing, decorative
3003	O / H14 / H18	Moderate strength, good formability	Pressure cookers, chemical equipment
5052	O / H32	High strength, marine-grade	Industrial discs, automotive
8011	O / H14	Excellent surface finish	Cookware lids, bottle caps

The most commonly ordered alloys are 1050, 1060, 1100, and 3003. If you need anodized aluminum circle plates, 1050 and 1060 give the cleanest anodized surface. For pressure cookers and heavy-duty cookware, 3003-O or 3003-H14 is the standard choice.

3. Standard Sizes and Specifications

Aluminum circle plates are available in a wide range of diameters and thicknesses. Below is our standard production range:

4. Key Applications of Aluminum Circle Plate

The round aluminum plate is used in virtually every sector that requires a lightweight, corrosion-resistant, formable disc. Here are the major end-use categories:

4.1 Cookware and Kitchen Utensils

The largest application for aluminum circle plate globally is cookware. Alloys 1050, 1060, 1100, and 3003 are used to produce pots, pans, woks, pressure cooker bodies, and flat lids. The aluminum circle pan blank is the starting point for most non-stick and bare aluminum cookware. Deep drawing and spinning are the two main forming methods.

We supply cookware manufacturers in Turkey, Brazil, Vietnam, South Korea, and across Southeast Asia. Our circles are produced with tight thickness tolerance (±0.03 mm) and smooth, burr-free edges to reduce forming defects.

4.2 Road Signs and Traffic Equipment

Round traffic signs, regulatory signs, and reflective sign blanks use aluminum plate circular discs as the substrate. Alloy 5052-H32 and 1100-H14 are standard for this segment because of their high strength and good surface adhesion for screen printing and reflective film lamination.

4.3 Lighting Reflectors and LED Fixtures

High-purity 1050 and 1060 aluminum circle plates are spun or stamped into parabolic reflectors for street lights, industrial lighting, and LED downlights. The high reflectivity of polished aluminum makes it ideal for optical reflector applications.

4.4 Industrial and Engineering Discs

Aluminum discs with center holes are used as pulley blanks, flange components, and machine parts. Alloys 5052 and 6061 are chosen where strength is critical. Round aluminum plates are also used as base plates, end caps, and speaker grille frames.

4.5 Decoration and Arts

Anodized aluminum circle plates are popular for medallions, awards, nameplates, dye sublimation blanks, and decorative panels. The 1050 and 1100 alloys anodize cleanly and accept bright color finishes.

5. Aluminum Circle Plate vs. Other Aluminum Forms

Product Form	Shape	Production Method	Typical Use
Aluminum Circle Plate	Round disc	Punched / rolled from coil	Cookware, signs, reflectors
Aluminum Sheet	Rectangular flat sheet	Rolling	Construction, fabrication
Aluminum Coil	Continuous rolled strip	Hot/cold rolling	Stamping, forming, slitting
Aluminum Circle Ring	Round disc with center hole	Punched from coil	Pulleys, flanges, grilles
Aluminum Strip	Narrow flat roll	Slitting from coil	Channel letters, fins, trim

The key difference between a round aluminum plate and other forms is that circle plates are net-shape or near-net-shape — they are ready for immediate forming with minimal material waste compared to cutting circles from rectangular sheets.

6. Aluminum Circle Price: What Affects the Cost?

Aluminium circle price depends on several factors. Understanding these will help you budget accurately and compare supplier quotations:

Price Factor	Impact	Notes
Alloy Grade	High	1050/1060 < 3003 < 5052 < 6061
Thickness	High	Thicker = more material = higher cost
Diameter	Medium	Larger blanks use more material
Temper (O vs H14/H18)	Medium	Soft temper (O) is lower cost; H18 costs more
Surface Treatment	Medium-High	Mill finish cheapest; anodized/polished adds cost
Order Quantity (MOQ)	High	Lower price per kg at higher tonnage
LME Aluminum Price	Variable	Tied to global commodity market
Delivery Requirement	Medium	FOB, CIF, or DDP affects final landed cost

Note: Aluminium circle price fluctuates with LME aluminum ingot prices. We recommend locking in pricing with a purchase order when the market is stable.

7. How to Cut a Circle in Aluminum Plate or Sheet

Many fabricators and workshops need to cut custom circles from rectangular aluminum sheet or plate. Here are the most common methods used in industry:

7.1 Circle Shear (Rotary Cutter)

A circle shear or circle cutter is the most common tool for cutting circles in aluminum sheet up to about 3 mm thick. The sheet is clamped at the center, and a rotating blade cuts the radius. This is the cleanest method for small to medium production runs.

7.2 CNC Plasma or Laser Cutting

For thicker aluminum plates (3 mm and above), CNC plasma cutting or fiber laser cutting gives accurate results. Laser cutting is preferred for high-tolerance applications because it leaves a clean, narrow kerf with minimal heat distortion.

7.3 Waterjet Cutting

Waterjet cutting is the best method for cutting a circle in aluminum plate where no heat-affected zone is acceptable. It works on all thicknesses and leaves a smooth edge. The downside is higher cost per piece compared to shearing.

7.4 Hole Saw or Jigsaw

For one-off or workshop use, a hole saw attached to a drill press cuts small aluminum circles cleanly. A jigsaw with a metal blade can cut larger circles using a pivot guide. Use cutting lubricant to extend blade life and improve edge quality.

If you need pre-cut aluminum circle plates in large quantities, ordering from a dedicated circle manufacturer like us is more cost-effective than cutting from sheet. We ship ready-to-form discs that reduce your scrap and processing time.
