What Are 3105 Aluminum Uses

In the field of packaging materials, 3105 aluminum alloy has become an ideal choice for bottle cap manufacturing due to its unique combination of properties. As an important member of the 3xxx series of rust-proof aluminum, 3105 alloy is based on aluminum-manganese, and optimizes performance by adding trace amounts of copper, magnesium and other elements, achieving a good balance between strength, corrosion resistance and processing adaptability.

3105 h24 aluminum adopts the incomplete annealing process after cold working hardening, that is, partial softening treatment is carried out after cold rolling strengthening, so that the material has both high strength (tensile strength ≥ 240MPa) and moderate ductility. This process not only avoids the strength loss caused by complete annealing, but also reduces the brittleness problem caused by simple cold working, which is especially suitable for the forming needs of complex structures.

Advantages

Excellent corrosion resistance

By strictly controlling the copper impurity content (≤0.1%), 3105 alloy exhibits excellent corrosion resistance in humid environments, ensuring the long-term storage safety of products such as alcoholic beverages.

Good electrical and thermal conductivity

The conductivity reaches 41%, which not only meets the electrical conductivity requirements of electronic components, but also makes it suitable for food packaging that is sterilized by high-temperature cooking.

Precise surface quality

The high-precision rolling process is adopted, and the surface of the plate is smooth and flawless, meeting the post-processing requirements such as color printing and coating, and improving the appearance and texture of the bottle cap.

Environmentally friendly and recyclable

The natural recyclability of aluminum alloy makes it an important choice for sustainable packaging, which is in line with the modern green production concept.

Diversified application scenarios

Wine and beverage packaging

Beer, liquor and carbonated beverage bottle caps are typical applications of 3105 aluminum foil for bottle cap. Its deep drawing performance ensures the precise fit between the bottle cap and the bottle mouth, and its high strength ensures the reliability of the seal while withstanding the long-term erosion of the acidic environment of the wine.

Cosmetics and pharmaceutical fields

Cosmetic bottle caps require materials that are both beautiful and safe. The surface of 3105 alloy is easy to color and print, and it meets food contact standards. It is widely used in packaging such as creams and perfumes. Pharmaceutical bottle caps must meet aseptic filling and tamper-proof design, and its good processability can achieve one-piece molding of complex structures.

Industrial and architectural uses

In addition to bottle caps, the alloy is also used to manufacture building components such as roof panels, corrugated boards, and eaves gutters, using its rust resistance and weather resistance to extend the life of outdoor facilities. In addition, it can also be seen in electronic components, lighting accessories and other fields. Welcome to learn more about 3105 aluminum uses from us.
