The Ultimate Guide to 0.5mm, 0.6mm, & 0.9mm Aluminium Circle Sheets for Cookware
Aluminium circles are increasingly emerging as preferred materials in cookware fabrication, particularly with the prominent 1050, 1100, and 3003 H14 aluminium sheet alloys. these alloys' unique properties, tempering standards, and technical specifications ultimately ensures manufacturers produce high-quality cookware, such as frying pans and cooking pots.
The Importance of Aluminium Circles in Cookware Manufacturing
Cookware demands an alloy that not only assures durability but also guarantees corrosion resistance, great thermal conductivity, and good workability. Thus, 0.5mm, 0.6mm, and 0.9mm aluminium circle sheets crafted with alloys such as 1050, 1100, and 3003 H14 meet kitchen requirements, displaying versatility across various user needs.
Properties of 1050, 1100, and 3003 H14 Aluminium alloy Circles
1. Alloy 1050:
- Chemical Composition: 99.5% minimum aluminium content.
- Characteristics: Excellent corrosion resistance, high thermal and electrical conductivity. Typically, it exhibits Ei > ~ 0200; O3 is as per ASTM grade specifications.
- Common Uses: Ideal for items requiring high thermal properties and being gently induction-cooked.
2. Alloy 1100:
- Chemical Composition: 99.0% aluminium content.
- Characteristics: Similar to the 1050 alloy; it features good workability and excellent corrosion resistance but offers slightly reduced strength compared to 3003.
- Common Uses: Suitable for making degreasing cook pots, finish pots, and kitchenware.
3. Alloy 3003 H14:
- Chemical Composition: Approximately 97.25% - 99.31% aluminium, manganese content between 1.0 - 1.5%.
- Characteristics: Offers higher strength compared to the previous alloys. Many manufacturers prefer using this type due to its excellent machining properties. Thermal conductivity is similar but with moderately superior hardness.
- Common Uses: Utmost versatility for cookware needing excellent forming characteristics.

Tempering: The Significance
Temper determination effectively enhances the physical properties of aluminium circle sheets. The H14 designation signifies a specific temper for the metal, illustrating that typical alloy structures undergo significant strengthening during cold working methods. This sheet method allows the aluminium’s manufacturing resilience to furnish pots and pans edge on long exposure, even through the most exact prepping processes.
Standards Implemented: Bringing It All Together
Manufacturers should ensure following internationally recognized standards such as ALS (Aluminium Liftsetting Standard) or ASTM B221 whole of scale for polished surface finish near the final fabric stage. Moreover, unique cookware products via aluminium circles follow methods such as anodizing or brushing to surface streamline, improving aesthetics without static problems faced within whites or ceramic counterparts.
