Selling 3003 O / H18 Non-Stick Aluminum Circles for Cookware , Factory pric

The 3003 non-stick aluminum circle is a high-quality aluminum disc product made
from 3003 aluminum alloy. It is produced through rolling, drawing, stamping, and
annealing processes. As a member of the Al-Mn (aluminum-manganese) series, 3003
aluminum offers excellent corrosion resistance, good ductility, outstanding thermal
conductivity, and superior forming performance.

It is widely used in kitchen cookware, utensils, lighting reflectors, electronic shells, and
pressure vessels due to its balance of strength, lightweight properties, and formability.

Different Tempers and Applications

3003-O Aluminum Circle
The "O" temper refers to the fully annealed (soft) condition. This state offers maximum
ductility and formability, making it ideal for deep drawing, spinning, and complex
forming processes. The O temper minimizes cracking and waste during manufacturing.

3003-H18 Aluminum Circle
The "H18" temper is strain-hardened to achieve maximum hardness. It is suitable for
applications where higher strength and hardness are required, or as a base material for
composite bottom cookware. Some manufacturers also use H18 circles for shallow
drawing or stamping, producing cookware with a stiffer body.

Why Choose 3003 Aluminum Circles for Non-stick Cookware?
1. Excellent Heat Conductivity

It ensures even heating of the pot body, rapid temperature rise, effectively reduces
cooking time, and enhances the user experience.

2. Outstanding Corrosion Resistance

Thanks to its manganese content, 3003 aluminum resists oxidation and chemical
corrosion, even in humid and high-temperature kitchen environments, ensuring a
longer cookware lifespan.

3. Superior Formability and Weldability

The alloy's good ductility allows deep drawing, spinning, and stamping without
cracking, meeting the diverse forming needs of cookware manufacturers.

4. Food-Grade Safety

It meets the stringent standards of various countries for food contact materials (EU
LFGB, US FDA, etc.) to ensure that no harmful substances are released during cooking,
making it safe and reliable.

5. Lightweight

Aluminum has a density that is only one-third that of steel, making non-stick pans
lighter and conducting heat faster, meeting the energy-saving and ergonomic needs of
modern kitchens.

Application Fields

Non-stick cookware: the core material for all kinds of non-stick woks, frying pans, and
soup pots.
Pressure Cooker Liners: Ensures uniform heat under pressure and durability under
repetitive use.
Bakeware: Used in cake pans, pizza trays, and baking sheets for efficient heat transfer.
Appliance Inner Pots: Ideal for rice cookers, multi-functional pots, and other household
kitchen appliances.
