What characteristic of aluminum makes it suitable for certain HVAC applications?

Aluminum's corrosion resistance is a key characteristic that makes it particularly suitable for HVAC applications. In environments where moisture is present, such as in heating, ventilation, and air conditioning systems, metals are prone to rust and degradation. Aluminum forms a protective oxide layer when exposed to air, preventing further corrosion and extending the lifespan of the material. This property is especially important in applications where durability and maintenance are concerns, such as ductwork and fittings exposed to varying humidity levels.

While aluminum also possesses low density, good thermal conductivity, and flexibility, its corrosion resistance is paramount in ensuring the reliability and efficiency of HVAC equipment over time. This makes aluminum an ideal material choice in the industry, providing both performance and longevity.
