As a materials science expert with a focus on the longevity and applications of various metals, I can provide you with a comprehensive understanding of how long aluminum lasts and the factors that can influence its lifespan.
Aluminum is a versatile and widely used metal known for its lightweight, corrosion resistance, and high strength-to-weight ratio. It is commonly used in various industries, including construction, automotive, aerospace, and packaging, due to these properties. The lifespan of aluminum can vary greatly depending on the application, environmental conditions, and protective measures taken.
In general, aluminum has a natural resistance to corrosion due to the formation of a protective oxide layer on its surface when exposed to air. This oxide layer acts as a barrier, preventing further oxidation and corrosion. However, the longevity of aluminum can be significantly enhanced through various surface treatments and protective coatings.
Painting: Applying a paint coating to aluminum can provide an additional layer of protection against environmental factors such as moisture, sunlight, and chemicals. Painted aluminum can last for several decades, with proper maintenance and depending on the quality of the paint and application process.
Dip-galvanizing: This process involves dipping aluminum into a molten zinc bath, which results in a protective zinc coating on the aluminum surface. Galvanized aluminum can offer enhanced corrosion resistance, especially in harsh environments, and can extend the lifespan of aluminum components.
Cadmium plating: Cadmium is another protective coating that can be applied to aluminum to improve its corrosion resistance and wear properties. Cadmium-plated aluminum is often used in applications where high levels of corrosion resistance are required.
Anodizing: Anodizing is an electrochemical process that forms a thicker, more durable oxide layer on the surface of aluminum. This process not only enhances the corrosion resistance of aluminum but also provides additional benefits such as increased hardness and a wide range of color options. Anodized aluminum can last for many years, even in harsh environments.
The lifespan of aluminum can also be influenced by factors such as the quality of the aluminum alloy, the thickness of the material, and the specific environmental conditions it is exposed to. For instance, aluminum in a marine environment may corrode faster due to the presence of saltwater, while aluminum used in a dry, indoor environment may last much longer.
In summary, untreated aluminum can still have a long lifespan, particularly if it is in a relatively benign environment. However, with the right protective measures, such as painting, galvanizing, or anodizing, the lifespan of aluminum can be significantly extended, potentially lasting for 50 years or more.

You usually paint it or dip-galvanize it or cadmium-plate it, and then it can last 50 years easy. Aluminum can be left out and it will be fine for 50 years, it will do better if painted or anodized.
