What is aluminum strip?
The raw materials of aluminum strip (Aluminum strip/Aluminum strip) are pure aluminum or aluminum alloy cast aluminum coil, hot-rolled aluminum coil.
Which is rolled into thin aluminum coils of different thicknesses and widths by cold rolling mill, and then longitudinally cut into aluminum strips of different widths by slitting machine according to the purpose.
Classification of aluminum strip
Commonly used aluminum strip alloy grades are 1050, 1060, 1070, 1100, 3003, 3004, 5005, 5052, 8011, ecc.
Commonly used states are O state and H state, ecc. O represents soft state, and H represents hard state.
Numbers can be used after O and H to indicate the degree of softness and hardness, as well as the degree of annealing.
The specific uses of aluminum strip are: transformer aluminum strip (transformer aluminum foil), aluminum strip for high-frequency welding hollow aluminum strip, aluminum strip for fin radiator, aluminum strip for cable, aluminum strip for stamping, aluminum strip for aluminum edge strip, ecc.
The categories of aluminum alloy strips are: pure aluminum strip, transformer aluminum strip, super hard aluminum strip, all-soft aluminum strip, semi-hard aluminum strip, and rust-proof aluminum strip.
Application of different grades of aluminum strips
Aluminum strips have many uses, such as aluminum-plastic composite pipes, Cavi, optical cables, Transformers, Riscaldatori, blinds, ecc.
1060 is used for applications requiring high corrosion resistance and formability, but not high strength.
Chemical equipment is a typical application.
1100 is used for processing parts that require good formability and high corrosion resistance but do not require high strength, such as chemical products, food industry equipment and storage containers, sheet metal parts, deep-drawn or spun concave vessels, welded parts, scambiatori di calore, printed boards, targhette, reflective equipment.
3004 extruded tubes are used only for all-aluminum can bodies, parts that require higher strength than 3003 lega, chemical product production and storage equipment, sheet metal parts, building baffles, cable ducts, sewers, and various lighting parts.
3003 Cold-worked bars, cold-worked wires, rivet wires, forgings, foils, and heat sinks are mainly used for processing parts that require good forming properties, elevata resistenza alla corrosione, or good weldability, or workpieces that require these properties and need higher strength than 1000 leghe della serie, such as tanks and tanks for transporting liquids, serbatoi di pressione, dispositivi di archiviazione, scambiatori di calore, Attrezzatura chimica, serbatoi di carburante dell'aeromobile, oil pipes, reflectors, Attrezzatura da cucina, washing machine cylinders, rivetti, and welding wires.
5052 This alloy has good forming properties, Resistenza alla corrosione, candleability, forza a fatica, and medium static strength.
It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts for transportation vehicles and ships, instruments, street lamp brackets and rivets, hardware products, ecc.
Special application areas of aluminum strips
Due to its unique physical and chemical properties, aluminum strips have special application value in many fields.
Tra loro, the two most eye-catching special application areas are the power industry and the packaging industry.
In the power industry, aluminum strips are mainly used to manufacture power equipment such as transformers and cables.
The conductivity of aluminum strips is second only to copper, but its density is only one-third of copper, which makes aluminum strips an ideal material for power transmission and distribution systems.
Especially in dry-type transformers, aluminum strips as winding materials can not only ensure the normal operation of electrical appliances, but also significantly reduce the weight and cost of transformers.
Inoltre, the corrosion resistance of aluminum strips also enables it to maintain stable performance in various harsh environments and extend the service life of equipment.
In the packaging industry, aluminum strips also play an irreplaceable role.
Because aluminum strips have good barrier properties and can effectively prevent the intrusion of oxygen, moisture and light, they are widely used as packaging materials for food and medicines.
This packaging method can not only maintain the freshness and quality of food and medicines, but also prevent the intrusion of external pollutants, ensuring the safety and hygiene of products.
At the same time, aluminum strips also have good recyclability, meet environmental protection requirements, and reduce resource waste and environmental pollution.
FAQ
Q: What is the difference between aluminum strip and aluminum coil?
UN: Aluminum strip usually refers to a coil with a narrow width (≤500mm) and a thin thickness (0.1-3mm), which is suitable for precision processing; aluminum coil covers a wider range and can reach a width of 2500mm.
Q: How to choose the appropriate state (Temperare)?
UN:
- O state (soft state): easy to form, suitable for deep stamping.
- HX state (hard state): aumento della forza (such as H18 is the hardest), suitable for structural parts.
Q: How to avoid surface damage of aluminum strip during transportation?
UN: Packaging requirements: corner guards are added at both ends of the coil, wrapped with PE film + moisture-proof paper, and reinforced with steel strips and wooden pallets.
Q: Can aluminum strips be customized with special coatings (such as high-temperature resistant coatings)?
UN: It is feasible, but it requires additional cost and time.
Per esempio: PVDF coating, epoxy coating.
