Hot-Rolled Cookware Aluminum Circles Alloys 1050, 1060, 1070, 1100

Title

According to incomplete statistics, nearly half of the cookware worldwide is made of aluminum, with a cooking thermal efficiency of up to 93%, while stainless steel and cast iron reach only one-third of aluminum. Using aluminum discs for cookware significantly enhances the physical and chemical properties of kitchenware, improving conductivity, heat transfer, and heat resistance to ensure better cooking performance and high-quality meals.

HAOMEI Aluminum's hot-rolled aluminum circle, with excellent ductility, thermal conductivity, and eco-friendly characteristics, have become an essential raw material for pots, pans, saucepans, fry pans, and more. Among them, alloys 1050, 1060, 1070, 1100, etc., as 1 series pure aluminum alloys, are widely used in the manufacture of high-end cookware due to their high purity and excellent comprehensive performance.

Advantages of Hot-Rolled Aluminum Circles

Compared with cold-rolled aluminum circles, hot-rolled aluminum circle discs offer distinct differences in processing and performance, making them especially suitable for deep drawing and spinning processes. They ensure stable product quality and high yield.

1. Excellent Formability
Hot-rolled aluminum discs have uniform structure, fine grain, and low internal stress. During deep drawing, spinning, and stretching, they are less prone to cracking.

2. High Thermal Conductivity
1-series aluminum alloys feature high thermal conductivity and uniform heating, improving cooking efficiency.

3. Superior Corrosion Resistance
In high-temperature and humid kitchen environments, hot-rolled aluminum discs exhibit outstanding corrosion resistance, extending cookware lifespan.

4. Eco-Friendly & Sustainable
Aluminum is 100% recyclable, aligning with global sustainability trends. More cookware brands are adopting aluminum for its recyclability.

Why Choose Hot-Rolled Aluminum Blanks for Cookware?

Superior Thermal Conductivity: Pure aluminum conducts heat far better than iron or stainless steel, enabling fast, even heating. This prevents localized burning of food and ensures better cooking results.
Excellent Formability: Soft texture and great ductility make aluminum discs ideal for deep drawing and spinning into complex cookware shapes with high yield rates.
Lightweight: Aluminum’s low density makes cookware lighter, improving user comfort.
Great Corrosion Resistance: Naturally forms a dense oxide film, resisting corrosion from water and food acids.
Safe & Non-toxic: Free from harmful heavy metals such as lead or cadmium, compliant with food-contact safety standards.
Cost-Effective: Lower raw material costs compared with other alloys, keeping cookware prices competitive.

Applications of Hot-Rolled Aluminum Discs

Cookware Industry: Fry pans, saucepans, stockpots, steamers, sauté pans, etc.
Kitchenware Products: Trays, plates, coffee pots, kettles, and more.
Industrial Uses (extended): Lamp reflectors, road signs, and other spinning products.

Common Surface Treatments

Anodizing: Creates a hard, corrosion-resistant oxide layer with multiple color options (e.g., hard anodized black pans).

Non-stick Coatings (Teflon, etc.): Provides superior non-stick performance, widely used in modern cookware.

Ceramic Coatings: PTFE-free, healthier non-stick alternatives.

Production Process of Hot-Rolled Aluminum Discs

Aluminum ingot smelting → Casting & rolling → Hot rolling → Cold rolling → Cutting → Disc stamping → Deburring → Surface treatment

The hot rolling process ensures compact grain structure and avoids cracks or brittleness commonly seen in cold rolling. After precision cutting and polishing, the discs have smooth surfaces, suitable for anodizing and coating processes.

Features of HAOMEI Aluminum Discs

Smooth edges (no burrs)
Uniform thickness
Excellent surface quality
High dimensional accuracy

How to Choose the Right Alloy for Your Cookware?

Cookware Type: Pressure cookers require higher strength (1100), while pots and pans can use 1050 or 1060 for good performance.

Forming Process: Softer tempers (O or H12) are ideal for deep drawing.

Surface Treatment: Ensure alloy compatibility with your preferred coating or anodizing.

Strength & Corrosion Requirements: Choose 1100 for higher demands.
