Title

As a dedicated aluminum circle manufacturer, we produce 3105 H14 aluminum circles designed for cookware forming processes such as deep drawing, stamping, spinning, and press forming. Cookware producers choose 3xxx series alloys when they need a balanced combination of formability, strength, surface stability, and cost control at scale.

3105 is an Al-Mn based alloy with small additions that improve strength compared with common alternatives while keeping good workability. In the H14 temper, it provides a controlled half-hard condition that supports stable forming and dimensional repeatability in high-volume cookware production. Our role is to deliver consistent material performance from coil selection through circle blanking, with traceable quality control and predictable lead times for export supply chains.

Material Overview: Why 3105 H14 for Cookware

Cookware bottoms, pots, pans, and lids demand reliable forming behavior, good surface appearance after polishing or anodizing, and adequate mechanical strength to resist denting during use. 3105 H14 aluminum circles are commonly specified for:

• Deep drawn cookware bodies requiring controlled flow and uniform wall thickness

• Spun cookware components where edge quality and grain control matter

• Pressed lids and shallow drawn parts requiring consistent hardness

• Anodized or coated cookware where surface cleanliness and uniformity affect finish quality

Compared with softer tempers, H14 offers improved rigidity and handling strength during downstream processing. Compared with harder tempers, it helps reduce cracking risk in deeper draws when process parameters are optimized.

Product Features and Performance

Good corrosion resistance: 3105 aluminum alloy belongs to the Al–Mn alloy series. The manganese content effectively improves rust resistance and corrosion resistance, making it especially suitable for cookware that is exposed to water, steam, and food over long periods, ensuring durability and safety.

Excellent formability and processability: The H14 temper indicates a semi-hard condition (partially strain-hardened). While maintaining certain strength, it still offers good plasticity and ductility, making it ideal for complex forming processes such as deep drawing and spinning. It enables efficient production of complex-shaped cookware components (e.g., pots and kettle bodies) with good surface quality, and is less prone to cracking or producing drawing lines.

Moderate strength and lightweight: Compared with pure aluminum (e.g., 1060), 3105 achieves higher strength through the addition of manganese and a small amount of copper, allowing thinner-wall and lighter cookware for better handling. Its low density also helps reduce overall weight for easier transport and operation.

Good thermal conductivity: Aluminum is an excellent heat-conducting material, and 3105 retains this characteristic, transferring heat quickly and evenly, reducing localized overheating, and improving cooking efficiency and energy savings.

Meets food-grade application requirements: 3105 aluminum alloy is widely used in food packaging (such as bottle caps and cans) and cookware manufacturing. Its composition is safe with no harmful element migration, and it complies with environmental and food-contact regulations such as RoHS and REACH, ensuring safe use.

Excellent surface treatment performance: It has good oxidation properties and is easy to anodize, coat, or spray, achieving an attractive, wear-resistant, and easy-to-clean surface finish, enhancing both appearance and practicality.

Technical Parameters (Typical)

The values below represent typical capability ranges for cookware-oriented 3105 H14 aluminum circles. Final parameters are confirmed by purchase order and agreed specification.

Note: Mechanical properties (yield strength, tensile strength, elongation) depend on gauge and processing history. We provide test certificates per lot when required.

Manufacturing Capabilities

As a factory focused on aluminum circles and discs, we control production steps that directly affect cookware performance.

Coil sourcing and incoming verification

We start from qualified 3xxx series coils and verify key parameters including chemical composition, thickness, surface condition, and mechanical consistency. Material traceability is maintained from coil to finished circle bundles.

Blanking and circle cutting

We use dedicated blanking lines and tooling designed for aluminum disc production. Key controls include:

• Tooling clearance optimized for clean edges

• Lubrication and cutting speed control to reduce surface marking

• Online inspection for diameter and burr

Surface protection and packaging

Cookware circles are sensitive to handling marks. We apply interleaving or protective layers as needed and use export-grade packaging to protect against humidity and abrasion during shipment.

Customization Options for Cookware Producers

Cookware factories differ in forming routes, tooling, and finishing methods. We regularly customize the following:

• Diameter schedule and mixed-size shipments

• Thickness selection optimized for deep drawing or spinning

• Surface level requirements for anodizing or coating

• Edge deburring targets for automated feeding lines

• Packaging configuration for high-speed unloading and line-side storage

For customers evaluating alloy alternatives within the same family, we also supply 3000 Series Aluminum circle products for comparative trials.

Application Scenarios and Target Industries

Cookware manufacturing

Primary uses include:

• Deep drawn pots, saucepans, and stockpots

• Stamped or spun frying pans

• Kettle bodies and lids

• Pressure cooker components (where process design allows)

Kitchenware and home appliance components

3105 H14 aluminum discs are also used for:

• Reflector-type formed parts requiring stable shape

• Covers, trims, and shallow drawn housings

• Decorative anodized parts where surface stability matters

Comparison with Other Common Alloys

Selecting the right alloy and temper affects scrap rate, forming window, and finished-product durability. Below is a practical comparison from a manufacturer perspective.

3105 vs 3003

• Formability: Both are suitable for many cookware shapes. 3003 aluminum circle is widely used for deep drawing; 3105 offers comparable workability with strength advantages depending on gauge and processing.

• Strength: 3105 typically provides higher strength potential in similar tempers, supporting improved dent resistance.

• Use case: 3003 is often chosen for general deep drawn cookware; 3105 is selected when a higher strength baseline is needed without moving to more expensive or less formable options.

3105 vs 3004

• Strength: 3004 aluminum circle generally has higher strength than 3105 and is used where stronger performance is required.

• Forming and processing: 3004 may require more careful forming control in deep drawing, depending on temper.

• Use case: 3105 is a balanced choice for cookware producers looking for stable forming with moderate-to-high strength.

3105 H14 vs softer tempers (O, H12)

• H14 advantages: Better handling rigidity, less deformation during transport and feeding, improved finished-part stiffness.

• Softer temper advantages: Wider deep-drawing window for extreme draws.

• Selection guidance: For standard cookware depths and spinning operations, H14 often provides a good balance. For very deep draws, a softer temper may be evaluated.

Supply Stability, Technical Support, and Long-Term Cooperation

Cookware production depends on predictable material behavior and on-time shipments. As a manufacturer, we focus on process stability, lot traceability, and clear technical communication to support your forming line.

We provide:

• Stable monthly capacity for export orders

• Consistent coil-to-circle control to reduce forming variation

• Technical support on thickness selection, edge requirements, and temper suitability

• Sampling and trial order support for new cookware projects

If you are developing or scaling cookware production with 3105 H14 aluminum circles, we can align specifications to your tooling, forming route, and finishing requirements, and support long-term supply programs with repeatable quality.
