Anodizing is an electrochemical process that produces a protective oxide layer on the surface of aluminum, which makes it more resistant to corrosion, abrasion, and wear. While anodized aluminium is a popular choice for windows and other architectural applications, there are certain climates where it may not perform as well. Here are some examples of bad climates for anodized aluminium:

High chloride environments

Anodized aluminium can be vulnerable to corrosion in areas with high levels of chloride, such as in coastal areas or near swimming pools. Chloride can penetrate the protective layer of anodized aluminum, causing it to corrode and degrade over time. In these areas, it may be better to choose a different type of finish, such as Kynar, which is more resistant to corrosion.

Acidic environments

Anodized aluminum can also be vulnerable to corrosion in areas with acidic environments, such as in industrial areas or areas with high levels of air pollution. Acidic environments can erode the protective layer of anodized aluminum, causing it to degrade over time. In these areas, it may be better to choose a different type of finish, such as a powder-coated finish, which is more resistant to corrosion.

High heat environments

Anodized aluminium can be vulnerable to discoloration and fading in areas with high temperatures, such as in desert areas or near industrial heat sources. High temperatures can cause the oxide layer of anodized aluminium to break down, which can cause it to lose its color and luster over time. In these areas, it may be better to choose a different type of finish, such as a powder-coated finish or Kynar, which are more resistant to heat.

Overall, anodized aluminium can perform well in a range of climates, but it may not be the best choice in areas with high levels of chloride, acidic environments, or high temperatures. In these areas, other types of finishes or materials may be more suitable to provide long-lasting and effective protection.
