How do aluminum outdoor sculptures handle exposure to hydraulic fluids in mechanical installations?

Aluminum outdoor sculptures are often chosen for their durability and resistance to environmental factors, but how do they fare when exposed to hydraulic fluids in mechanical installations? Hydraulic fluids, commonly used in machinery, can pose challenges due to their chemical composition, which may degrade certain materials over time.

Aluminum naturally forms a protective oxide layer, which helps resist corrosion from hydraulic fluids. However, prolonged or repeated exposure can still cause damage, especially if the fluid contains aggressive additives. To enhance protection, many aluminum sculptures are treated with specialized coatings, such as powder coatings or anodizing, which create an additional barrier against chemical exposure.

Regular maintenance, including cleaning and reapplication of protective coatings, can further extend the lifespan of aluminum sculptures in such environments. By understanding these factors, artists and installers can ensure the longevity and aesthetic integrity of aluminum outdoor sculptures in mechanical settings.
