1050 ho aluminum discs are high-end, high-purity aluminum substrates used in lightweight cookware molding. Produced in strict accordance with ASTM B209, the substrate aluminum content is ≥99.50%, classifying it as a high-purity, low-impurity industrial pure aluminum grade. Compared to the commonly used 1100 aluminum discs, the 1050 grade implements stricter and more refined control over impurities such as iron and silicon, keeping the total impurity content below 0.5%, resulting in higher substrate purity and superior material uniformity.
The HO fully annealed soft temper process completely eliminates processing stress, resulting in a uniform and delicate grain structure free of stress concentration defects. This makes it a core preferred raw material for the mass production of thin-walled cookware and precision-stretched cookware. As one of our main export categories, 1050 aluminum discs has long been a stable supplier to cookware manufacturers in many countries, focusing on the lightweight civilian cookware market. With its superior formability, excellent thermal conductivity, and complete food safety compliance, it has become the mainstream material for the production of high-end single-layer aluminum cookware and precision small cookware. It is compatible with various mainstream industrial cookware forming processes such as high-speed stamping, deep drawing, and precision spinning.
Compared to 3003 aluminum discs who has manganese alloy under the same working conditions, the 1050 aluminum alloy has a thermal conductivity of 230W/(m·K), demonstrating significantly higher thermal conductivity. The resulting cookware heats evenly, without localized high-temperature scorching on the bottom. It is a commonly used raw material for the blanks of single-layer aluminum pots, aluminum milk pots, small baby food saucepans, and kettles.
Haomei Aluminum uses 1050 ho aluminum discs specifically designed for cookware, sourced from hot-rolled billets through deep processing. Unlike ordinary cold rolled substrates, these aluminum discs are dense and free of porosity and pinholes. Supply thicknesses range from 0.35mm to 3.8mm, and diameters from 120mm to 750mm. Thickness tolerances are controlled to ±0.02mm across all dimensions, and end-face roundness error is less than 0.3mm. The aluminum discs undergo degreasing and dust removal, and double-sided film coating to prevent scratches, moisture damage, and oxidation during warehousing and ocean shipping. Precise dimensional accuracy is compatible with overseas automated continuous stamping production lines, keeping the stamping scrap rate below 1.2%, significantly reducing raw material costs for customers.
All our aluminum discs products have passed GB4806.9, US FDA, and EU LFGB food contact safety tests. Heavy metal leaching levels are far below international legal limits, making them safe for direct contact with drinking water and acidic/alkaline foods. They are also suitable for subsequent non-stick coating and hard anodizing surface treatments. High-purity aluminum has stable chemical properties and is resistant to weak acids and broth corrosion during daily use, preventing the pot from easily developing blackening or pitting corrosion on the inner wall.
Due to its material properties, 1050 ho pure aluminum has relatively low hardness, making it unsuitable for thickened composite woks requiring high strength and deformation resistance. However, it offers significant cost-effectiveness in the field of thin-walled, lightweight cookware, with raw material procurement costs lower than 3003 alloy aluminum discs. Leveraging the factory's integrated cutting and annealing production line, the grain state can be fine-tuned according to the customer's stamping process, and non-standard diameters can be customized as needed. With stable batch consistency and complete export compliance qualifications, 1050 ho aluminum discs continue to be the mainstream material for lightweight cookware projects in foreign trade, precisely meeting the large-scale, high-quality mass production needs of small and medium-sized cookware manufacturers worldwide.
