1050 Hot Rolled Aluminum Circle: The Ideal Deep Drawing Material for Cookware & Lighting

Product Overview: What is a 1050 Hot Rolled Aluminum Circle?

A 1050 hot rolled aluminum circle is a semi-finished product made from 1050 aluminum alloy sheet (with a purity of over 99.5%) that is first produced via a hot rolling process and then punched or sheared into a circular disc. Compared to cold-rolled circles, the hot rolling process results in a more uniform internal grain structure and superior ductility (deep drawability), making it especially suitable for manufacturing cookware, lamp shades, and various stamped parts that require complex stretch forming.

As a representative of the 1000 series pure aluminum, it possesses not only the lightweight characteristic of aluminum but also excellent thermal conductivity, corrosion resistance, and workability. It is a core foundational material for the cookware, lighting, appliance, and decorative industries.

Why Choose 1050 Hot Rolled Aluminum Circles? Core Advantages Explained

Advantage	Specific Performance	Value for You
Excellent Deep Drawing & Spinning Performance	The hot rolling process refines the grain structure, giving the material exceptional ductility. It resists cracking and wrinkling during deep drawing and spinning processes.	Increases product yield rate. Ideal for manufacturing complex-shaped items like pots (saucepans, frying pans), lamp shades, and vessels.
Outstanding Thermal Conductivity	1050 aluminum has a high thermal conductivity (approx. 229 W/m·K), enabling fast and even heat distribution.	Results in energy-efficient cookware that heats food uniformly, perfectly meeting the core needs of cookware manufacturing.
Good Corrosion Resistance & Surface Treatability	High-purity aluminum naturally forms a dense oxide film in air, providing corrosion resistance. The smooth surface is easy to treat with anodizing, painting, polishing, etc.	Products have a long service life and can achieve various finishes (e.g., non-stick coating, colored anodizing) through surface treatment.
Lightweight & Eco-Friendly	Low density makes it lightweight. Aluminum is 100% recyclable, aligning with green manufacturing principles.	Reduces product weight, saves energy, and enhances product market competitiveness.
Stable Material & Supply	Simple and stable chemical composition (see table below) and mature production process ensure batch-to-bility consistency.	Guarantees stability in your production process and reliability in your product quality.

Our Production Process & Quality Assurance

We are committed to providing stable, high-quality 1050 hot rolled aluminum circles. Our core process ensures consistent quality:

Premium Raw Materials: Use high-standard remelted aluminum ingots to control purity from the source.
Precision Hot Rolling: Rolling is performed above the recrystallization temperature, effectively breaking down the as-cast structure to obtain a uniform, refined grain—key to high ductility.
Controlled Annealing: Precise annealing according to the required temper (e.g., O temper) relieves internal stress and optimizes workability.
High-Precision Shearing: Use precision punching or CNC circle blanking equipment to ensure accurate dimensions and smooth, burr-free edges.
Comprehensive Testing:
- Dimensional accuracy (thickness, diameter)
- Surface quality (free of scratches, oil stains, corrosion)
- Mechanical properties (hardness, deep drawability via Erichsen cupping test)
- Chemical composition via spectroscopic analysis

How to Choose a Reliable 1050 Aluminum Circle Supplier? [Procurement Guide]

When choosing a partner, be sure to evaluate the following points:

Focus on Production Process: Explicitly ask if the circles are produced via a hot rolling process, which is crucial for deep-drawn products.
Quality Control & Testing Capability: Does the supplier provide complete test reports (e.g., material certificates, performance tests)? Can they provide samples for trial stamping?
Specification Flexibility: Can they provide non-standard thicknesses, diameters, or special surface pre-treatment based on your drawings?
Production Capacity & Lead Time: Do they have stable capacity to support your volume orders? What is the standard lead time?
Technical Support & Service: Can they provide material-related advice for your processing (e.g., drawing speed, die design)?

Frequently Asked Questions (FAQ)

Q: What’s the difference between 1050, 1060, and 1100 hot rolled aluminum circles?

A: All three belong to the pure aluminum series but have slightly different purities: 1050 (Al≥99.5%), 1060 (Al≥99.6%), 1100 (Al≥99.0%). Generally, higher purity offers better corrosion resistance and thermal conductivity but slightly lower hardness. 1050 offers the best balance of purity, performance, and cost, making it the most widely used grade in the cookware industry.

Q: What’s the difference between O temper and H18 temper? Which one should I choose?

A: O temper (Annealed) is the softest with the best ductility, specifically designed for deep drawing and spinning—the first choice for cookware manufacturing. H18 temper (Full Hard) is high in hardness but has almost no ductility, suitable for simple blanking or decorative parts that don’t require forming. Please choose based on your processing technique.

Q: What information do I need to provide when placing an order besides diameter and thickness?

A: Please be sure to specify: Alloy designation (1050), Temper (e.g., O), Thickness tolerance, Diameter tolerance, Surface finish requirements (e.g., protective film needed), and Estimated usage volume.

Q: Can you provide samples for testing?

A: Absolutely. We encourage customers to test samples before placing bulk orders to ensure the material fully meets your production requirements.
