1000 3000 Series Aluminum Disc Aluminum Circle Used For Kitchen Ware

Aluminum discs are widely used in cookware due to their lightweight, thermal efficiency, and formability. Combined with stamping, spinning, or deep drawing and anodizing/coating, they offer a balance of performance and cost-effectiveness for both household and commercial applications.

1) Pure Aluminum (1xxx Series)

Grades: 1050, 1060, 1070, 1100
Tempers: O (Annealed), H12/H14 (Half-Hard)

Advantages:

• Excellent thermal conductivity (~220 W/m*K), ideal for even heating.
• High formability, suitable for deep drawing/spinning (e.g., pots, steamers).

Typical Use: Traditional woks, stockpots, steamers.

2) 3003 Aluminum Alloy

Tempers: H24 (Semi-Hard), O (Annealed)

Advantages:

• Higher strength than pure Al (Mn-added), resists deformation.
• Better corrosion resistance, suitable for water-based cooking.

Typical Use: Saucepans, frying pans, lunch boxes.

3) 5052 Aluminum Alloy

Tempers: H32 (Stabilized), O (Annealed)

Advantages:

• High strength (Mg-added), durable for heavy-duty cookware.
• Superior corrosion resistance, ideal for salty/acidic foods.
• Works well with spinning/deep drawing.

Typical Use: Pressure cooker pots, commercial bakeware.
