As a dedicated aluminum circle and disc manufacturer, we produce 1050 H0 aluminum circle/disc products from controlled-chemistry 1000 series alloy and process them specifically for blanking and deep drawing. 1050 is a commercially pure aluminum grade known for high formability, excellent thermal conductivity, and reliable surface finishing behavior. The H0 temper (fully annealed) is selected when customers require maximum ductility, low earing tendency, and consistent forming performance across batches.
Our production focuses on stable mechanical properties, tight thickness control, burr management, and surface cleanliness because these are the variables that most directly influence downstream stamping, spinning, and deep drawing yield.

Alloy 1050 belongs to the 1xxx series and is valued for its purity-driven ductility and corrosion resistance. In applications such as cookware bodies, lamp reflectors, and spun components, 1050 provides predictable forming and a uniform response to anodizing or coating.
Temper H0 indicates a fully annealed condition. Compared with H12 or H14 tempers, H0 offers:
Higher elongation and lower yield strength, supporting deep drawing and severe spinning.
Reduced springback, helping control final geometry.
Improved crack resistance at tight radii when tooling is optimized.
When customers require higher rigidity for shallow forming or for components needing better dent resistance, we also manufacture other tempers within our 1000 Series Aluminum circle range.
Key Advantages of 1050 Aluminum Discs
Excellent Deep-Drawing and Spinning Performance
The O temper (fully annealed) means the aluminum disc is in its softest condition with very high elongation. This allows it to withstand significant deformation during deep drawing or spinning with a low risk of cracking, making it ideal for producing complex shapes such as deep pots and lamp shades.
Outstanding Thermal and Electrical Conductivity
As a high-purity aluminum, 1050 offers much higher thermal conductivity than alloyed aluminum (e.g., 3xxx or 5xxx series). In cookware applications, it ensures more uniform heating and significantly improves heat-transfer efficiency.
Superior Corrosion Resistance
Pure aluminum naturally forms a dense protective oxide film. 1050-O aluminum discs have inherent resistance to air, water, and many chemical media, do not rust, and meet food-grade safety requirements.
Excellent Surface Finishing Results
With its high material purity, 1050 aluminum is well suited for anodizing, coating, or polishing. After treatment, the surface appearance is uniform with strong coating adhesion, effectively enhancing product aesthetics and wear resistance.
High Cost-Performance Ratio
Compared with aluminum alloy discs, 1050 uses a mature production process and has lower raw material costs. For mass-produced industrial products that do not require very high tensile strength (such as nameplates, reflectors, and standard cookware), it is one of the most economical choices.
We manufacture 1050 aluminum circles/discs through a sequence designed to minimize variability:
Incoming coil and slab qualification: chemistry verification and surface inspection.
Hot and cold rolling: thickness reduction with flatness control.
Intermediate and final annealing: H0 temper achieved via controlled temperature profile to ensure uniform recrystallization.
Slitting and blanking: high-precision blanking to produce circles with controlled burr direction and consistent diameter.
Deburring and surface conditioning (as required): to improve safety in handling and reduce tooling wear.
Final inspection and packaging: dimensional checks, surface quality grading, and moisture-protected packing.
Key production points we control for deep drawing users:
Thickness tolerance and gauge stability to reduce uneven flow and wrinkling.
Grain structure consistency through annealing control to reduce orange peel risk.
Burr height and edge condition to prevent die scoring and early cracking.
Cleanliness to improve coating adhesion and reduce defects in anodizing.

For cookware and similar drawn parts, the performance of an aluminum circle/disc is not determined by chemistry alone. It depends on a combination of temper, thickness stability, and edge quality.
With 1050 H0, our targets are:
Uniform flow in the die to reduce earing and minimize trimming waste.
High ductility to support multi-stage draws.
Predictable response to lubricants commonly used in cookware drawing.
Where customers provide forming data (draw ratio, tool radius, press tonnage, lubricant), we can recommend thickness and diameter combinations and align inspection emphasis to the most sensitive parameters.
Surface cleanliness and uniformity influence polishing efficiency, coating appearance, and anodizing consistency. We supply mill finish circles suitable for:
Non-stick coating lines where cleanliness is essential.
Polished or brushed finishes for visible components.
Anodized parts where consistent surface response is required.
If your process is highly sensitive to handling marks, specify packaging method and whether interleaving or protective film is needed.

1050 H0 aluminum circle for cookware is commonly used for:
Frying pans and saucepans (spun or drawn bodies)
Pressure cooker components (non-structural drawn sections)
Lids and cookware accessories
The key requirement in cookware is stable formability and a clean edge. For customers producing high-volume cookware bodies, we support process repeatability through batch-level traceability and controlled annealing.
Spun and formed lighting parts benefit from:
High reflectivity potential after polishing
Good anodizing response
Excellent formability for complex profiles
For circular blanks used in signage, covers, and general stamping:
Diameter consistency supports automated feeding.
Flatness reduces misfeeds and improves stamping precision.
As a factory, our quality assurance is built around preventing forming issues rather than only measuring final dimensions. Typical controls include:
Chemical composition verification by supplier certificate review and internal checks.
Mechanical property monitoring aligned to H0 temper expectations.
Thickness mapping and coil-to-coil consistency tracking.
Diameter and roundness checks with calibrated gauges.
Burr inspection and edge quality grading.
Surface inspection under controlled lighting to identify scratches, pits, oil stains, and roll marks.
Upon request, we can provide documentation packages aligned with your incoming inspection system, including batch identification and inspection records.
Aluminum circles are sensitive to edge damage and moisture during transit. We pack to protect both geometry and surface:
Vertical or layered packing depending on diameter and thickness
Moisture barrier wrapping when sea freight is used
Pallet reinforcement to reduce shifting and edge impact

If you have automated de-stacking equipment, tell us your preferred stacking height, weight limits, and whether you require interleaving paper.
To quote and manufacture 1050 H0 aluminum circle/disc efficiently, we recommend confirming:

Packaging method and shipping terms
Providing your forming method and tooling constraints (draw ratio, die radius, number of draws) helps us select the most suitable process window and inspection focus.
1050 is often selected for maximum ductility and consistent forming. If your application needs a balance of formability and slightly higher strength, alternatives within the 1xxx series may be considered depending on your design and forming route. We manufacture multiple alloys and tempers and can align supply with the intended forming severity and finishing requirements.
1050 H0 aluminum circle/disc is a practical choice for deep drawing and spinning applications where ductility, thermal conductivity, and surface finishing behavior are important. As a manufacturer, we control rolling, annealing, blanking, and inspection processes to deliver circles with stable thickness, controlled edges, and consistent forming performance. For project-based sourcing or long-term supply programs, we can tailor diameter mix, tolerances, and packaging to your production line requirements.
