As the source billet for aluminum tube manufacturing, the alloy properties, dimensional accuracy, and processing performance of aluminium slugs directly determine the quality of the end product. Haomei Aluminum has been deeply involved in aluminum slugs manufacturing and export for many years. Relying on precise alloy proportioning and precision machining technology, we provide global aluminum tubes manufacturers with high-performance aluminum slugs suitable for various scenarios, covering core areas such as packaging, industry, and automotive, achieving a performance closed loop from raw materials to finished products.
The scientific selection of alloy systems is the core of adapting aluminum slugs for aluminum tubes manufacturing. The 1000 series pure aluminum slugs are our main product, occupying a core share of production capacity and shipments due to their superior processing performance and adaptability. We also offer other alloy series to meet differentiated needs.
1000 series pure aluminum slugs are primarily based on grades 1070 and 1060. Aluminum slugs 1070 boasts a purity of over 99.7%, with impurities strictly controlled below 0.3%. It exhibits a tensile strength of 70-75 MPa and an elongation of up to 42%, possessing excellent deep-drawing and cold-extrusion forming properties, making it the preferred blank for thin-walled aluminum tube manufacturing. Its superior ductility ensures uniform wall thickness after extrusion within ±0.03 mm, eliminating localized stress concentrations. This makes 1070 aluminum slugs suitable for high-end packaging applications such as cosmetic flexible tubes, lipstick tubes, pharmaceutical ointment tubes, and food toothpaste tubes. It also meets the requirements for subsequent anodizing, printing, and spraying surface treatments, with color adhesion 20% better than ordinary blanks. Furthermore, grade 1060 pure aluminum slugs offer significant cost-effectiveness, with a purity of 99.6%, a tensile strength of 65 MPa, and an elongation of 38%, making them suitable for cost-sensitive daily packaging aluminum tubes and general industrial conduits. To cover specialized needs, we simultaneously supply 3003 aluminum-manganese alloy slugs (corrosion-resistant, suitable for aerosol cans and pesticide tubing) and 6000 series aluminum-magnesium-silicon alloy slugs (high-strength, suitable for industrial fluid tubing and automotive structural tubing), forming a product matrix with the 1000 series as the core and multiple complementary series.
Dimensional precision control is the core competitiveness of Haomei aluminum slugs. We employ a continuous casting-rolling-high-speed stamping integrated process, achieving a stamping rate of 300 times/minute, coupled with real-time weight grading detection, to achieve precise control within the diameter range of 10-200mm and thickness of 2-30mm. Diameter tolerances strictly adhere to EN 570 standards, with a tolerance of ±0.03mm for 10-40mm specifications and ±0.06mm for 80-120mm specifications; thickness tolerances are subdivided according to specifications, controlled within ±0.05mm in the 2.8-6.5mm range, effectively reducing die wear and scrap rates during aluminum tube extrusion, reducing processing costs for customers by more than 15%.
Targeted process optimization gives our aluminum slugs a differentiated advantage. All aluminum slugs undergo softening annealing, with hardness controlled to HB 23±2, ensuring forming integrity during cold extrusion and avoiding defects such as cracking and wrinkling. The surface is treated with vibratory grinding and sandblasting, reducing oil adhesion by 80% compared to industry standards, making it particularly suitable for the cleanliness requirements of aluminum tubes used in food and pharmaceutical packaging. For non-standard aluminum tube production, we can provide customized slugs in various shapes, including dome and elliptical, to meet the personalized blank requirements of marker pen tubes and special industrial tubing.
With stringent quality control and full-scenario adaptability, Haomei aluminum slugs have become a stable supplier for many leading global aluminum tube companies. From everyday packaging such as cosmetic lipstick tubes and food toothpaste tubes to industrial precision components such as new energy battery casings and aerospace hydraulic pipes, we consistently adhere to both GB/T 4437.1 and ASTM B241 standards to provide customers with traceable, high-quality blanks. In the future, we will continue to optimize alloy formulations and processing precision to help the aluminum tube manufacturing industry meet its upgrade needs for lightweighting, high precision, and high durability.
