The Service Life of the Aluminum Profiles

weiye 0

Aluminum is one of the most popular materials in fabricating structural components and frames. One of the metal's main selling points is its service life. Very few materials can compete with its strength and longevity.

At Weiye Aluminium, we provide comprehensive value development throughout the whole aluminum life cycle, from mining to profile extrusion. Our clients and recycling are always at the forefront of everything we do.



A versatile and long-lasting material

Aluminium is a durable and versatile material with numerous applications. Its lightweight properties make it an excellent choice for transportation and working equipment, while its resilience allows it to be utilized for food packing without sacrificing quality. Furthermore, because it is recyclable, it may be reused multiple times with minimum energy consumption.


Manufacturing Process

The aluminum profile manufacturing process starts long before the metal hits our facility floors. It starts with the extraction of aluminum from bauxite via the Bayer process. Bauxite is an aluminum oxide-rich reddish mineral mined and refined into primary aluminum through various operations.

There’s another category of aluminum called secondary aluminum. It’s made from recycled parts and alloy elements. The process uses little energy, and the metal can be recycled several times without losing quality. After the aluminum mining operations, re-cultivation ensures that the land is restored closer to its natural state.


Extrusion Pressing

Extrusion produces aluminum profiles by pressing a heated aluminum piece through a molded die to achieve a precise profile. The extrusion process involves heating raw aluminum to soften it, which is then shaped and cooled. The end product is a lightweight, corrosion-resistant, and long-lasting material suited for various applications.


Service Life

Aluminum profile service Life depends on the alloy used, the quality and kind of surface treatments, the application, and environmental conditions. Aluminum profiles are designed to last years in most settings, including marine and coastal environments.


Factors Affecting the Service Life of Aluminum Profiles


Alloy Type

The kind of alloy used to make an aluminum profile can affect its durability. Alloys contain varied quantities of various metals, which can affect strength, corrosion resistance, and longevity. For instance, aluminum alloys containing silicon and magnesium have better resistance to corrosion than alloys lacking these metals, making them more appropriate for usage in marine environments.


Surface Coatings

Surface-coated aluminum profiles may undergo various surface treatments to enhance their appearance and performance, including service life. Common surface treatments include anodizing, painting, and powder coating. While painting and powder coating gives the metal color and texture, anodizing uses chemicals to form a protective oxide layer, increasing its corrosion resistance.

Generally, anodized aluminum profiles have a life expectancy of up to 30 years, while painted and powder-coated profiles have a maximum life expectancy of 20 years. However, anodized aluminum profiles are slightly expensive.



An aluminum profile's design might also affect its service life. For instance, profiles with smooth surface finishes can reduce the build-up of debris and dirt, which can stave off corrosion. Furthermore, profiles with larger cross-sectional areas are stronger and more durable, allowing them to handle heavier loads and last longer than thinner flimsy profiles.


Environmental Aspects

The setting in which a particular aluminum profile is used might drastically affect its life span. Aluminum profiles can corrode faster when exposed to moisture, high temperatures, and corrosive elements. Also, salt can accelerate corrosion, reducing aluminum's service life.



Proper maintenance is also essential for prolonging the lifespan of aluminum profiles. Occasionally, check profiles for indications of wear and tear and scrub them with a detergent solution to prevent rust and other damages. Also, greasier moving parts and swapping out worn parts will ensure the profile operates at peak performance for an extended period.

Ultimately, aluminum profiles' service life depends on many different variables, including the type of alloy, surface treatment, design, environmental exposure, and maintenance. Understanding these aspects and taking the appropriate measures to protect your aluminum profiles will help ensure they serve you long.
