Deep Drawing Aluminium Circle

2026-08-26

As a manufacturer with over 15 years of experience in aluminum circles manufacturing, deep drawing aluminium circles are our core forming product, designed for the global cookware, precision hardware, and lighting appliance industries. They are specifically developed for high draw ratios and multi-pass continuous stamping and spinning applications. Leveraging our independently controllable DC casting-hot rolling-cold rolling-annealing production line, Haomei Aluminum can achieve precise control over the entire chain, from alloy composition to mechanical properties, providing customers with stable forming and high batch consistency of deep drawing drawing quality aluminum circles.

Having worked with deep drawing aluminium circles for over a decade, I've always maintained that stable deep drawing performance stems from the homogenization and control of the microstructure at the ingot casting stage. This is also the core reason why many short-process manufacturers experience large fluctuations in deep drawing yields. Haomei deep-drawing aluminum circles are all made from large-size ingots cast using semi-continuous DC casting. The ingots undergo homogenization annealing at 480℃ for over 12 hours to completely eliminate compositional segregation and casting stress. Next, double-sided milling removes the surface segregation layer and subcutaneous defects. Combined with large-deformation hot rolling to break down the original casting structure, and finally, low-temperature long-time annealing, homogeneous recrystallization is achieved. This entire process ensures that the internal grain size of the material is stably controlled within ASTM 6-8 standards, and the compositional segregation is reduced by more than 60% compared to ordinary cast and rolled materials, eliminating occasional cracking problems caused by localized performance deficiencies from the raw material stage.

From a performance perspective, the measured parameters of all grades of deep-drawing aluminium circle products reach the upper-tier level in the industry:
1050 O high-purity deep drawing aluminium circle exhibits a stable elongation after fracture ≥30%, a cupping test IE value ≥10.8mm, and an ultimate deep drawing ratio of up to 2.4:1, making it the first choice for high-bodied milk pots, deep soup pots, and other extreme deep-drawing applications;
1100 O general-purpose deep drawing aluminium circle boasts an elongation ≥28%, a cupping value ≥10mm, and an ultimate deep-drawing ratio of 2.2:1, offering a balance of strength and formability, making it a cost-effective choice for conventional household cookware;
3003-O alloy deep drawing aluminium circle exhibits an elongation ≥25%, a cupping value ≥9.5mm, and an ultimate deep-drawing ratio of 2.0:1, with superior resistance to weak acid corrosion and high-temperature performance, making it suitable for brazed bottom products and high-pressure containers.

Haomei Aluminum can supply a full range of deep-drawn aluminum discs with thicknesses from 0.3mm to 6.0mm and diameters from 100mm to 1200mm. We support customization in multiple tempers, including O-temper and H12, and can also fine-tune the annealing process according to the customer's stretching process parameters to match the forming rhythm of different equipment. All deep drawing aluminium circle products undergo multi-stage degreasing, cleaning, and edge finishing before leaving the factory, ensuring a surface free of oil stains, burrs, and flash, allowing for direct stamping and reducing pre-processing steps and material costs for customers.

As a source manufacturer, we provide complete material certificates and mechanical property test reports for each batch of deep drawing aluminium circles, along with dedicated ocean-going packaging featuring double-sided PE film and fumigated wooden pallets, suitable for global cross-border delivery needs. All our products have passed FDA and LFGB food contact safety certifications and can be directly used in the production of food contact cookware.
