8011 Алюминиевая фольга для полужестких воздуховодов

Haomei Aluminium 8011 aluminium foil is specifically designed for semi-rigid duct systems. With its precise ingredient ratios and stringent process control, it has become a globally recognized premium substrate in the HVAC industry.

8011 aluminum foil uses Al≥98.5% as its base, scientifically proportioned with Fe (0.6-1.0%), и (0.5-0.9%), and trace amounts of Cu, Миннесота, and other elements, forming an alloy structure that combines strength and toughness. For semi-rigid aluminium ducting applications, we offer the following core specifications:

– Диапазон толщины:

0.06мм-0.20мм (60-200мкм), tolerance controlled within ±3%, meeting the mandatory requirement of aluminum foil thickness not less than 0.06mm in JGJ/T141-2017 standard.

– Width selection:

500mm-1600mm, supporting customized cutting to adapt to different duct diameter production lines.

– Tempering options:

O temper (мягкий), H22, H24, H26. Среди них, H24 temper has become the mainstream choice for semi-rigid ducts due to its balance between tensile strength of 140-180MPa and elongation of 12-16%.

– Обработка поверхности:

Glossy/matte finish available, surface tension stable at 32-36 плотность/см, ensuring strong adhesion to insulation materials.

Unlike ordinary civilian aluminum foil, Haomei 8011 aluminum foil for semi rigid duct overcomes industry pain points such as cracking, poor airtightness, and corrosion susceptibility of traditional duct aluminum foil through proprietary melting, прокатка, and passivation processes. It achieves core differentiated advantages in forming performance, уплотнительная способность, and weather resistance, perfectly meeting the needs of high-speed production and long-term operation of semi-rigid ducts.

– Structural Stability:

The uniform distribution of the iron-silicon reinforcing phase in the 8011 alloy allows the aluminum foil to maintain its shape memory during spiral forming and seam connection, resisting cracking even after repeated bending. The tear resistance at the seam reaches 18N/15mm, exceeding the national standard requirement of 15N/15mm.

– Ultimate Airtightness:

Haomei Aluminum employs a quadruple rolling process, controlling the pinhole rate of the aluminum foil to below 0.3 pins/m². Combined with continuous seam technology, the air leakage rate of the duct system is ≤0.5%, significantly reducing energy consumption.

– Full Temperature Range Adaptability:

Withstanding temperatures from -40℃ to 120℃, meeting ventilation needs in extreme climates. После 72 hours of continuous use at 120℃, mechanical properties retain ≥95%.

– Enhanced Corrosion Resistance:

Through online passivation treatment, a dense oxide film forms on the aluminum foil surface. No significant corrosion is observed after 1200 часов испытаний в нейтральном солевом тумане, making it particularly suitable for humid environments such as basements and coastal areas.

– Composite Compatibility:

Surface roughness Ra≤0.8μm, peel strength with insulation materials such as phenolic resin and glass wool ≥1.8N/cm, far exceeding the industry standard of 1.5N/cm, ensuring long-term structural stability of the composite duct.

With its balanced mechanical properties, excellent sealing and corrosion resistance, and safe flame-retardant characteristics, Haomei 8011 алюминиевая фольга for semi rigd ducting is suitable for manufacturing ventilation systems in various scenarios and under various working conditions. It can meet diverse usage standards for civil, коммерческий, промышленный, and special projects, leading the industry in versatility and adaptability.

– Commercial Buildings:

Central air conditioning systems for office buildings, hotels, hospitals, и т.п., suitable for low-to-medium pressure ventilation (≤150kPa), balancing ease of installation and system stability.

– Residential Ventilation Systems:

Fresh air systems, kitchen exhaust, bathroom exhaust; semi-rigid structure reduces noise transmission while possessing excellent fire resistance (A1-grade non-combustible material).

– Industrial Ventilation Engineering:

Cleanroom ventilation in electronics factories and pharmaceutical workshops; aseptic air supply systems in food processing plants; the metallic inertness of aluminum foil effectively prevents secondary contamination.

– Special Environment Applications:

Ventilation in underground spaces such as subways and tunnels; air conditioning systems for mobile equipment such as ships and locomotives; maintaining structural integrity and sealing performance under vibration conditions.

As a manufacturer specializing in aluminum foil production for 20 лет, Haomei Aluminum has established a comprehensive quality control system from alloy smelting to finished product slitting. We utilize German SMS Group cold rolling mills to ensure uniform thickness; online spectral analysis monitors compositional deviations in real time; and each batch of products undergoes three core tests: tear resistance, airtightness, и коррозионная стойкость, providing complete third-party testing reports.

8011 aluminum foil is not only a raw material for semi-rigid ducts but also a fundamental guarantee for the efficient operation of ventilation systems. Haomei Aluminum empowers products with technology and wins trust with quality. We look forward to providing customized solutions for your duct manufacturing projects, jointly creating energy-saving, Безопасно, and durable ventilation systems.
