Different colors of aluminum foil for air conditioning fin stock material

The core component of the air conditioner is the evaporator, which absorbs heat from the room and discharges it outside through the refrigerant. Air conditioning fins are one of the important parts of the evaporator, and have different colors. The main colors are bare, blue, and gold/golden. Air conditioning aluminum foil is also called air conditioning fin aluminum foil and hydrophilic aluminum foil for air conditioner heat exchanger. Commonly used alloys mainly include: 8011, 8006, 3102, 1100; commonly used tempers are HO/O, H22.

Why does air conditioning fin stock aluminum foil have different colors?

The colors of air conditioner fins can be divided into bare/pure, blue and gold/golden. Bare color refers to the original aluminum material without any treatment. Blue refers to a blue oxide layer formed after anodizing of aluminum. Gold refers to a golden oxide layer formed after anodizing of aluminum.

Features of different colors of aluminum foil for air conditioning fin stock material

1. Bare air conditioner aluminum foil

Bare air conditioner fin aluminum foil is characterized by a silvery gray or aluminum color without any treatment and are suitable for ordinary home air conditioners. The advantages of bare air conditioning fin stock aluminum foil are that they are relatively cheap, have stable quality and have a long service life. However, the disadvantage of bare air conditioning fins is that they are easily oxidized, resulting in white oxides on the surface, which affects the appearance.

2. Blue air conditioner aluminum foil

The characteristic of blue air conditioner fin aluminum foil is that they are blue in color and have been anodized to produce a blue oxide layer/hydrophilic layer on the surface. The advantages of blue air conditioning fin stock aluminum foil are high aesthetics, smooth surface, and not easy to oxidize. Moreover, the blue oxide layer can increase the hardness and corrosion resistance of air conditioning fins, extending their service life. The disadvantage of blue air conditioner fins is that the price is relatively high.

3. Gold air conditioner aluminum foil

The gold air conditioner fin aluminum foil is characterized by their golden color. After anodizing, a golden oxide layer/hydrophilic layer is produced on the surface. The advantages and disadvantages of gold air conditioning fins are the same as those of blue air conditioning aluminum foil. They have beautiful appearance, good corrosion resistance, high hardness, good hydrophilicity, can adapt to harsh or extreme environments, and extend service life.

Uses of different colors of aluminum foil for air conditioning fin stock material

The color of air conditioning fin aluminum foil is determined according to different use environments and requirements. Ordinary home air conditioners use bare air conditioning fins because the price is cheap, have stable quality, and have a long service life. Commercial air conditioners use blue or gold air conditioner fins, because the blue or gold oxide layer can increase the hardness and corrosion resistance of the air conditioner fins, making them suitable for long-term use and high-demand environments.
Although the color of the air conditioner fins does not affect its basic functions, its aesthetics and durability are an important factor affecting users’ purchase and use. Therefore, when purchasing an air conditioner aluminum foils, you should choose the air conditioner fins according to your needs.
