With many years of experience in the aluminum processing industry, I firmly believe that high-quality round aluminium slugs are not simply metal blanks, but rather the core foundation for efficient production in downstream industries. At Haomei Aluminum, we deeply integrate precision manufacturing with customer needs, creating round aluminum slugs that combine performance and stability, becoming the trusted choice for customers in the global packaging, automotive, and electronics industries.
From a technical perspective, our round aluminum slugs use high-purity AA1070 aluminum alloy as the core material, with a purity of over 99.7%. Combined with precise composition control—the content of impurities such as silicon and iron is controlled below 0.2%—this ensures excellent ductility and formability. In terms of key dimensions, we cover a full range of specifications with diameters from 20-116mm and thicknesses from 3-10mm, while also supporting customized production. Dimensional tolerances strictly adhere to DIN 59604 standards, with diameter errors controlled within ±0.03mm and thickness uniformity deviations not exceeding 0.02mm. This means customers can significantly reduce scrap rates during stamping, deep drawing, and other processing. Through precise annealing at 450-460℃, the hardness is stabilized at 16-19HB, ensuring rigidity during processing and possessing excellent deep-drawing performance, making it particularly suitable for the forming needs of thin-walled containers.
Among our many years of overseas collaborations, the one that impressed me most was our cooperation with a well-known European aerosol can manufacturer. They faced the problem of traditional aluminum slugs being prone to cracking and having insufficient surface smoothness during stretching, leading to low production line efficiency. To meet their specific needs, we customized round aluminum slugs with a diameter of 63.5mm and a thickness of 4.2mm, optimized the alloy grain structure (grain size controlled at level 5), and employed a tumbled surface treatment to enhance smoothness. After the collaboration, the client’s stamping pass rate increased from 82% to 99.3%, daily output on a single production line increased by 30%, and annual cost savings exceeded €150,000. This type of case demonstrates our product advantages: not only meeting parameter standards, but also technological optimization based on actual application scenarios.
Haomei’s core competitiveness is further reflected in its end-to-end quality control and service advantages. During the production process, chemical composition is monitored in real time using a spectrometer, dimensional accuracy is monitored using a laser diameter gauge, and SGS test reports are provided for each batch of products. As one of the top three aluminum profile manufacturers in China, we have a 35,000㎡ production base and four intelligent production lines. Our MOQ is as low as 500kg, with standard specifications readily available. We support small-batch trial orders and have export experience covering more than 20 countries in Europe, America, and Southeast Asia. We can flexibly meet the technical standards and logistical needs of different regions.
In addition to round shapes of aluminum slugs, we also offer customized aluminum slug solutions in domed, square, oval, rectangular and irregular shapes. We can adjust the outline dimensions and corner designs (such as rounded squares, stepped irregular shapes, etc.) according to the forming requirements of the customer’s end product. The base material still uses the high-purity AA1070/1060 aluminum alloy system, maintaining the same impurity control standards (silicon + iron ≤ 0.3%) and annealing process (hardness 16-19HB) as our round products. Dimensional tolerances are accurate to ±0.05mm, suitable for special applications such as irregularly shaped pharmaceutical packaging cans, precision automotive parts, and electronic component housings. Previously, we customized oval aluminum slugs for a North American electronics company. By optimizing the stress structure design, we successfully solved the pain point of stress concentration at the corners during deep drawing, increasing the stamping yield to 98.7%, fully demonstrating our process flexibility and customization capabilities in the field of multi-shaped aluminum slugs.
Whether it’s cosmetic tubes, pharmaceutical packaging, automotive sensor housings, or electronic capacitors, Haomei’s round aluminum slugs, with their precise craftsmanship, stable performance, and attentive service, become reliable partners for your business growth. We firmly believe that high-quality products are never just isolated parameter stacking, but rather the result of meticulous craftsmanship throughout the entire process from raw materials to delivery – this is the key to Haomei winning the long-term trust of its global customers.
