As the head of production technology at Haomei Aluminum, I have long been deeply involved in the R&D, manufacturing processes, and quality control of cooking aluminum circle. Combining this with years of practical experience exporting to cookware manufacturers in Europe, America, the Middle East, and Southeast Asia, providing customers with practical and verifiable professional selection references.
1050 aluminum alloy belongs to the 1000 series industrial pure aluminum, with an aluminum content ≥99.5%, and is a recognized mature base material in the cookware industry. We focus on kitchenware-specific specifications: thickness 0.4–6.0mm, diameter 50–1200mm, commonly available in O temper, H14, H12, H18, etc., prioritizing compatibility with mainstream cookware forming processes such as deep drawing, spinning, stretching, and double-bottoming. The material boasts stable mechanical properties, with an elongation ≥25% (O temper), tensile strength of 75–150 MPa, and thermal conductivity of approximately 222 W/(m·K). 1050 aluminum circles provide uniform heat conduction and prevents localized overheating in cookware, kettles, baking pans, and multi-layered bottoms, making it suitable for use with open flames, induction cooktops, ovens, and more.
From a production technology perspective, we strictly control three key aspects to ensure the one-time molding rate and durability of our 1050 cooking aluminum circles.
1. Composition and purity control:
Adhering to ASTM B209, EN573-1, and GB 4806 food contact standards, impurities such as iron and silicon are precisely limited to reduce stamping cracks and surface pitting. This ensures the material is non-toxic, odorless, acid and alkali resistant, corrosion resistant, and consistently passes salt spray tests, preventing rust even with long-term use.
2. Process precision control:
Utilizing a cast-rolled/hot-rolled billet + precision cross-cutting circular sheet production line, flatness is ≤0.5mm/m, thickness tolerance ±0.02mm, and diameter tolerance ±0.5mm. The surface is free of scratches, roller marks, and slag inclusions, resulting in stronger adhesion after subsequent spraying, oxidation, and non-stick treatments.
3. Heat treatment and forming adaptability:
O-state full annealing ensures uniform softening, while H-state provides a stable strength gradient. Customized materials are available for different processes such as stretching pot bodies, spinning kettle bodies, and composite steel-aluminum bottoms, reducing customer scrap rates and improving line efficiency.
The practical advantages of 1050 cookware aluminum circles are all verified on-site: High formability, continuous deep drawing without cracking, and spinning without deformation; high thermal conductivity, ensuring even heating of the pot body, reducing scorching, and saving energy; food-grade safety, meeting multiple international food contact certifications, ensuring stable export customs clearance; lightweight and durable, with moderate strength, providing a good feel and long service life for kitchenware.
As a source 1050 cooking aluminum circle factory and exporter, Haomei Aluminum's core competitiveness lies in its integrated technology, delivery, and service.
- Stable processes and quality control:
End-to-end online thickness and width measurement, and surface inspection. Each batch provides material certificates, performance reports, and SGS/food contact reports, ensuring high batch consistency and eliminating the need for repeated trial moldings in long-term partnerships.
- Flexible customization capabilities:
Thickness, condition, and surface finish (mill/glossy/anodized substrate) can be customized according to customer mold dimensions, equipment parameters, and molding processes. Fast response for small batches and stable supply for large batches.
- Mature export system:
Years of experience exporting cookware aluminum circles, familiar with international packaging, ocean moisture protection, customs documents, and certification requirements. Packaging uses wooden frames + moisture-proof film + partitions to prevent deformation and scratches during transportation. Supports FOB, CIF, DDP, and other terms.
- Technical collaboration support:
We don't just sell materials; we can assist customers with trial molding, process optimization, and yield improvement solutions. We provide full technical support from material selection to mass production, reducing overall customer costs.
The core of competition in the cookware industry is yield, quality, and delivery efficiency. While seemingly ordinary, 1050 aluminum circles actually demand meticulous attention to detail in composition control, heat treatment precision, surface quality, and dimensional stability. Haomei Aluminum, grounded in advanced manufacturing technology and adhering to export-quality standards, focuses on providing global kitchenware manufacturers with highly reliable, adaptable, and cost-effective 1050 cookware aluminum alloy circles.
We insist on letting data speak for itself, verifying with samples, and demonstrating our strength through mass production. We are committed to establishing long-term, stable, and technology-driven supply relationships with our clients to jointly enhance the competitiveness of our cookware products.
