Air duct hose is a key flexible connection material in ventilation system, and its performance directly affects the operation effect of the system. Aluminum strip is a material used to make ventilation ducts, hoses and other air delivery equipment. Aluminum strip for air duct flexible tube is widely used in HVAC (heating, ventilation and air conditioning) systems because of its lightness, corrosion resistance and good formability.

 
Specifications of aluminum strip for air duct flexible tube:
- Usually made of aluminum alloy (such as 1060, 1100, 3003, 3004, 8011, etc.).
- Thickness range: 0.06mm to 0.15mm, selected according to pipe diameter and pressure requirements.
Ultra-thin type (0.06-0.08mm): used for low static pressure air conditioning system, taking into account flexibility and cost.
Standard type (0.10-0.12mm): suitable for fresh air system, balancing strength and elasticity.
Thickened type (0.13-0.15mm): for industrial exhaust, enhancing negative pressure resistance.
- Width: usually 60mm to 1000mm, can be customized by slitting unit.
- Length: standard roll length 100m to 4000m, support on-demand slitting.
- Annealing state:
O state (full soft): elongation ≥30%, easy to stamp and form, suitable for special-shaped pipe joints.
H24 state (semi-hard): taking into account rigidity and flexibility, fatigue resistance is improved by 40%.
- Forming method: through spiral curling or rolling forming, a corrugated structure is formed to enhance elasticity.
 
Features of aluminum strip for air duct flexible tube:
- Lightweight:
The low density of aluminum makes the aluminium strip light and easy to install and transport.
- Corrosion resistance:
The naturally formed oxide layer on the surface of aluminum makes it have good corrosion resistance and is suitable for use in humid or corrosive environments.
- Good formability:
Aluminum strip is easy to cut, bend and form, and can adapt to a variety of design requirements.
- Excellent thermal conductivity:
Aluminum has good thermal conductivity and can effectively conduct heat, suitable for areas requiring heat exchange.
- Recyclability:
Aluminum is a recyclable material that meets environmental protection requirements.
 
Application of aluminum strip for air duct flexible tube:
