99.7% aluminum slugs for collapsible tubes making (such as toothpaste tubes and ointment tubes) is a cylindrical billet made of high-purity aluminum, which is formed into a tubular container through a cold extrusion process. Aluminum with a purity of up to 99.7% has good ductility and flexibility, which enables aluminum slug to be easily extruded or stretched into various shapes during processing, and is suitable for making collapsible tubes through processes such as cold extrusion or deep drawing. At the same time, high-purity aluminum also has good corrosion resistance, which can effectively protect the items in the tube, and the material is relatively light, which is convenient for transportation and use.
The following are the detailed characteristic parameters of 1070 aluminum slugs for collapsible tubes making:
Composition: 99.7% pure aluminum (grade 1070), in line with industrial pure aluminum standards (such as GB/T3190-1996), with extremely low content of major impurities (iron ≤0.25%, silicon ≤0.20%), ensuring high ductility and corrosion resistance.
Aluminum content: ≥99.7% in line with GB/T3190-1996 standard
Main impurities: Fe≤0.25%, Si≤0.20% Other impurities≤0.3%
Density: 2.70 g/cm³ Lightweight characteristics
Conductivity: ≥62% IACS Excellent conductivity
Tensile strength: 60-95 MPa Moderate strength, easy processing
Elongation: ≥15% High plasticity performance
Size range:
Diameter: 3–10 mm, can be made into a final aluminum tube with a diameter of 13.5–40 mm.
Thickness: 0.3–4 mm, can be customized according to needs.
Surface treatment: Use tumbling or sandblasting process to enhance the surface roughness to facilitate printing and coating adhesion.
Performance advantages of aluminum slugs for collapsible tubes:
– High plasticity: suitable for cold extrusion molding, not easy to crack;
– Good corrosion resistance: suitable for sensitive contents such as medicines and cosmetics;
– Non-toxic: meets the hygiene standards of pharmaceutical and food packaging.
Application scenarios of aluminum collapsible tubes:
Collapsible aluminum tubes are widely used in the packaging of cosmetics, medicines, foods, etc. For example, cosmetic packaging such as lipstick tubes, mascara tubes, toothpaste tubes, and some ointment tubes are often made of 1070 aluminum slugs as raw materials.
– Pharmaceutical industry: such as 19mm diameter ointment tube (capacity 20g), sterile and good sealing are required;
– Cosmetics: cream and lotion tubes, brand logos need to be printed on the surface;
– Industrial product packaging: adhesives, chemical products.
Aluminum slug is usually made into a collapsible tube by a one-time impact extrusion process. This process can make the tube seamless and leak-free, and there will be no rebound defects during use. It can effectively prevent bacteria, germs and other potentially harmful substances from entering the tube and better protect the contents.
