Aluminum Strip For Deep Stamping

Aluminum strip for deep stamping is a strip material made by rolling, slitting and other processing technologies of aluminum alloy. It has good deep stamping performance and can withstand large deformation without breaking during the stamping process. It is suitable for manufacturing various parts that require deep drawing.

Specification of aluminum strip for deep stamping:

- Alloy type: Commonly used aluminum strip alloys for deep stamping include 1xxx series, 3xxx series, 5xxxx series, 8xxx series, etc. For example, 1060 belongs to 1000 series pure aluminum, which has the advantages of high elongation, excellent tensile strength and conductivity, high formability, etc., and can meet conventional processing requirements. 3xxx series aluminum alloys generally add manganese elements to aluminum, and have good corrosion resistance and processing performance. 5000 series aluminum alloys usually have better strength and ductility, suitable for deep drawing. 8xxx series aluminum alloys usually also have good formability and certain strength.

- State: Common states include O state (annealed full soft state), H18 state (no annealing, highest hardness), H14/H24 state (partial annealing, balance strength and formability), etc. Among them, O state aluminum strip has a large elongation and is suitable for deep drawing and stretching products; H18 state has high hardness and is suitable for some stamping parts with high hardness requirements; H14/H24 state achieves a good balance between strength and formability.

- Specifications: The thickness is generally around 0.15mm - 3mm, and the slitting width is 10mm and above. The specific specifications can be customized according to customer needs. In addition, the length of the aluminum strip can also be slit and coiled according to actual usage.

Taking the common 1060 hot rolled aluminum strip as an example, the aluminum content of 1060 aluminum strip reaches 99.6%, which is also called pure aluminum strip. It has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, good elongation and tensile strength, can meet the requirements of conventional stamping and stretching, and has high formability. At the same time, the aluminum alloy itself has a high elastic modulus and good plastic deformation ability, and can achieve uniform deformation during deep drawing. However, aluminum alloy is prone to work hardening during deep drawing and rolling, that is, with the increase of strain, the hardness and strength of the material increase accordingly, which limits its deep drawing depth and deformation degree to a certain extent, and needs to be controlled by appropriate heat treatment or alloy element adjustment to control the hardening rate.

Features of aluminum strip for deep stamping:
- Material characteristics: It has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, can meet the requirements of conventional stamping and stretching, has high formability, light weight and high specific strength.
- Processing performance: It can be processed into various shapes by rolling, stretching, shearing, etc. to meet different process requirements.
- Surface quality: The surface is usually smooth, with high flatness and no obvious defects, such as cracks, corrosion spots, etc., which is conducive to good fit with the mold during deep drawing, reducing friction and defects.

Application areas of aluminum strip for deep stamping:
- Packaging industry: It is used to make packaging materials for food, medicine, cosmetics and other products, such as aluminum foil packaging, cans, etc., using its corrosion resistance and good formability to effectively protect the quality and safety of the products.
- Construction industry: It can be used for architectural decoration, such as the manufacture of roofs, walls, ceilings, doors and windows, etc., and provides reliable construction solutions with its light weight, corrosion resistance and easy processing.
- Electronic and electrical industry: As one of the main materials for wires and cables, it is used to transmit electricity and signals. In addition, it is also used in the manufacture of electronic and electrical equipment such as transformers, inductors, capacitors, etc.
- Automobile manufacturing industry: It is used to manufacture automobile radiators, intake manifolds, body panels and other parts, which helps to improve the fuel efficiency and comfort of automobiles.
- Daily necessities industry: It manufactures tableware, lamp parts, decorations, etc. to meet various needs in people's daily lives.
