PP cap 3105 h24 aluminum coil

PP cap 3105 h24 aluminum coil refers to H24 state aluminum alloy 3105 coil used to make polypropylene caps. This type of aluminum is typically used in applications that require a combination of strength and formability, such as the production of various types of lids and closures.

• PP Cap: Stands for Polypropylene Cap and refers to a closure or lid made from polypropylene, a thermoplastic polymer.
• 3105: This is an aluminum alloy. In the aluminum alloy naming system, the first number (3 in this case) designates the series and subsequent numbers designate the alloys within that series.
• H24: This is the name of the tempering state of aluminum. H24 means the aluminum has been strain hardened and then partially annealed. This is a work-hardened state.
• Aluminum Coil: This indicates that the material is in the form of a coil, a continuous long piece of material that is wound into a spiral.

PP cap 3105 h24 aluminum coil specifications

0.012mm-0.5mm 3105 h24 aluminum coil is an ordinary pp cap aluminum material. This thickness covers aluminum coils and foils.

The common specifications of PP cover 3105 H24 aluminum coil may vary depending on the manufacturer and region. The following are some possible common specification ranges, but please note that this is for reference only, and the specific specifications should be based on the information provided by the supplier:

• Thickness: Usually between 0.15 mm and 0.3 mm. This is the thickness of the aluminum coil, which can be selected according to the requirements of the PP cover.
• Width: Generally between 1000 mm and 2000 mm. The choice of width usually depends on the size of the PP cover and the requirements of the production equipment.
• Coil Weight: The specific coil weight depends on the length, width and thickness of the roll. Generally speaking, this may be between 1 and 5 tons.
• Inner Diameter: Generally 505 mm. This refers to the diameter of the inside of the reel.
• Surface Treatment: May include aluminizing, coating or other surface treatments to provide desired appearance and performance.

Please note that this is a general guide only and actual specifications may vary depending on manufacturer, order requirements and market demand. If you require specific specifications, it is recommended to contact the aluminum coil supplier or manufacturer directly for accurate information.

Questions you may be concerned about PP cap aluminum coil

Question: In addition to 3105 and 8011 aluminum coils, which alloys can also be used as PP cover materials?

Answer: In addition to 3105 and 8011 aluminum coils, other alloys commonly used for PP cover materials are 1060, 3104, 5052 and 5182.

• 1060 PP cap aluminum coil: This is a pure aluminum alloy with excellent formability and processability, suitable for caps with simple shapes and low requirements. However, its strength is relatively low.
• 3104 PP cap aluminum coil: It has high strength and good formability, and is suitable for manufacturing PP caps with complex shapes. Compared to 1060, 3104 alloy has higher strength.
• 5052 aluminum coil for PP cap: Offers higher strength and corrosion resistance, suitable for applications requiring higher strength and corrosion resistance. It is an option for PP covers that have higher requirements for strength and corrosion resistance.
• 5182 aluminum coil for PP cap: This is an alloy with better strength and corrosion resistance, suitable for manufacturing PP caps with higher requirements. It is generally superior to 5052 in strength and corrosion resistance.

Question: What are the surface requirements for aluminum covered coils?

Answer: No matter which alloy it is, the surface of the aluminum cover coil must be kept clean, uniform in color, safe and hygienic. This is to ensure that the final PP cover has good appearance and hygiene standards.

PP cap 3105 h24 aluminum coil production process

The aluminum ingot is melted - rolled - and rolled repeatedly until the workpiece becomes as thin as possible. It is expected that the thinner the roll, the higher the rolling pressure and the more complex the process steps.

The production process of PP cover 3105 H24 aluminum coil usually includes the following steps:

1. Aluminum ingot melting: Aluminum ingots are heated to the melting point and then melted into liquid aluminum. This usually happens in a furnace.
2. Continuous Casting: The molten aluminum is continuously cast through a continuous casting machine to form a preliminary aluminum slab.
3. Hot Rolling: After heating the preliminary aluminum slab, it is rolled on a hot rolling mill. This stage helps further refine the crystal structure and shape of the aluminum.
4. Cold Rolling: Hot rolled aluminum coils may be cold rolled to further reduce their thickness. Cold rolling can improve the surface quality of aluminum and adjust its mechanical properties.
5. Quenching: Changing the crystal structure of aluminum and increasing its hardness through rapid cooling.
6. Stretching and Leveling: Stretching the 3105 aluminum coil to obtain the required size and flatness.
7. Deep Drawing: The 3105 aluminum coil is fed into the deep drawing forming machine and deep drawn according to the design of the PP cover.
8. Heat Treatment: 3105 aluminum coils may undergo heat treatment steps to adjust their hardness and other mechanical properties.
9. Cutting: Cut the aluminum coil into the required length according to the customer's requirements.
10. Coating: Aluminum coils may be coated to provide additional protection or to change their surface properties.
11. Packaging and Delivery: The final PP cover 3105 H24 aluminum coil is packed and delivered to the customer or downstream manufacturer.

These steps may vary based on different manufacturers and customer requirements, but generally include the basic process described above.
