Aluminum Circles Wafer Blanks for Cookware Lamp Cover Road Sign
Aluminum circles, also known as aluminum wafers, aluminum blanks, or base plates, are flat round discs punched or cut from aluminum sheets or coils. With the feature of lightweight, excellent corrosion resistance, and superior formability, aluminum wafers have become the preferred raw material for a wide range of industries, for example aluminum circle plates for cookware, lamp covers, or road traffic signs, very common in daily life.
Aluminum circles sizes
We supply a wide range of aluminum circles with customizable sizes and alloys:
Diameter: 100 mm – 1200 mm
Thickness: 0.3 mm – 10 mm
Alloy Series: 1000, 3000, 5000, 8000 series (1050, 1060, 1100, 3003, 5052, 8011, etc.)
Tempers: O, H12, H14, H18, H22, H24
Surface Finish: mill finish, bright surface, anodized, coated
Tolerance: precise thickness and diameter control to meet deep-drawing requirements
Custom sizes and alloy grades are available to suit different applications.
Different sizes different uses
Small size circles (≤ 300 mm): widely used for bottle caps, cosmetic containers, and aluminum slugs for packaging.
Medium size circles (300–600 mm): ideal for lamp covers, kitchen utensils, and aluminum circle pans.
Large size circles (≥ 600 mm): commonly used for pressure cookers, frying pans, and aluminum circle plates for road traffic signs.
Aluminum discs manufacturing process
Raw material preparation – select aluminum coils or sheets.
Punching / Blanking – wafers are produced through precise aluminum circle punch operations.
Annealing – improves ductility for deep drawing.
Surface treatment – polishing, anodizing, or coating as required.
Quality inspection – check dimensions, thickness, flatness, and surface finish.
This process ensures every aluminum wafer has uniform quality and meets the strict standards of cookware and industrial applications.
Applications
Cookware Industry: frying pans, pressure cookers, non-stick pans, and base plates.

FAQ
Q1: What are aluminum wafers used for?
They are mainly used in cookware, lighting, packaging, and traffic signs.
Q2: Which alloy is best for cookware?
Alloys like 1050 and 3003 are widely used due to excellent formability, while 5052 offers higher strength.
Q3: Can aluminum wafers be anodized or coated?
Yes, anodized and coated finishes are available to improve appearance and corrosion resistance.
Q4: What is the difference between aluminum wafers, blanks, and slugs?
Aluminum wafers and circles usually refer to flat round discs, while slugs are smaller, thicker pieces often used for bottle caps and aerosol cans.
Q5: How do I choose the right thickness?
Cookware requires thinner wafers (1–3 mm), while traffic signs and industrial uses often need thicker plates (up to 10 mm).
