Bare Aluminium Foil 8011 Alloy For Various Fin Air Conditioning
Overview of Bare Aluminium Foil 8011 Alloy For Various Fin Air Conditioning:
For now, air conditioners are gradually developing in the direction of miniaturization, high efficiency, long life and high quality. The air-conditioning heat exchange fins are also developing in the direction of ultra-thin and high-strength. In the 1980s, the thickness of the heat exchange fins was 015-02 ram, while today's thickness is only between 0.09 and 0.15 mm. In addition, in order to improve the life of the air conditioner, reduce power consumption, improve ventilation quality and improve the cooling effect, the
Coated heat exchangers with various functions are typically anti-corrosion heat exchangers, surface hydrophilic heat exchangers, surface hydrophobic heat exchangers, mildew-proof heat exchangers and self-lubricating heat exchangers.

Uncoated aluminum foil refers to the aluminum foil paper after rolling and annealing without any form of surface treatment. In my country 10 years ago, the aluminum foil used for air-conditioning heat exchangers in foreign countries about 15 years ago was all uncoated aluminum foil. Even at present, about 50% of the heat exchange fins used in foreign developed countries are still uncoated aluminum foil, while in my country, this ratio is about 60%.
The alloy grades of aluminum foil for heat exchange fins are mainly 1100120080118006, etc. In terms of use, air conditioners do not have strict requirements on the chemical composition of aluminum heat exchange fins. 3A21 aluminum alloy without surface treatment has good corrosion resistance, high mechanical properties such as strength and elongation, and high hardness. The choice of alloy depends primarily on the final mechanical properties the material can achieve and the ease of the ant process. For example, the 1100 aluminum alloy with higher purity is easier to roll, while the 8011 alloy is more difficult.
Aluminium Foil Food Grade 3003 Bright Side Container Foil 3003 series aluminum plate is a common product of the aluminum-manganese alloy series
