Aluminium strip for semi-rigid aluminum round duct is a material used to manufacture ventilation ducts, which are widely used in heating, ventilation and air conditioning (HVAC) systems. Semi-rigid aluminum duct strip should have good ductility, corrosion resistance, weatherability and workability. It is able to resist the external environment to a certain extent and maintain the stability and durability of the material. At the same time, it also has good strength and toughness, and can withstand certain mechanical stress and impact.

Types of aluminum alloys commonly used in aluminium strip for semi rigid aluminum round duct include 1060, 3003, 8011, and others. These aluminum alloys have good corrosion resistance, formability, and strength, making them suitable for air transportation. The state includes O temper (soft temper), O temper means that the aluminium strip has been annealed, has good flexibility and plasticity, easy to process into a variety of shapes, and is suitable for bending and forming of air ducts. The thickness of aluminium strip for semi grid round duct is generally between 0.08mm and 0.15mm. The choice of thickness depends on the size of the duct, the usage environment and the load requirements.

Performance characteristics of aluminium strip for semi rigid aluminum round duct are:
- Corrosion resistance: Aluminum strip material has good corrosion resistance and is suitable for use in humid or dusty environments.
- Lightweight: Aluminium strips are relatively lightweight, making them easy to transport and install.
- Good formability: Aluminum duct strip is easy to process and form, suitable for manufacturing various shapes of air ducts.

Aluminium strip for semi-rigid aluminum round duct is mainly used to make aluminum foil duct and other ventilation equipment. Aluminum foil air duct is a lightweight, high-strength ventilation duct material with excellent heat insulation, sound insulation and fireproof performance. It is widely used in construction, industry, transportation and other fields, such as air supply ducts in air conditioning system, smoke exhaust ducts in smoke exhaust system, mechanical ventilation equipment and so on. As one of the main raw materials for aluminum foil duct, the quality and performance of aluminum strip for semi-rigid round duct directly affect the quality and performance of aluminum foil duct.

By choosing the right 8011 O aluminium strip for semi-rigid aluminum round duct, the performance and service life of semi-rigid aluminum duct can be effectively improved to ensure the efficient operation of the ventilation system.
