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