Aluminum stands out in the world of decorative materials for its excellent decorative and protective effects. In this article, we’ll explore the main properties of aluminum, underlining its significance in various applications.

Performance Characteristics of Aluminum

Pure aluminum, known for its low strength, has limited uses. But when alloyed with elements like magnesium, silicon, manganese, copper, zinc, iron, chromium, and titanium, it transforms into aluminum alloys with varied and enhanced properties. These alloys undergo further strengthening and hardening through cold working and heat treatments, significantly improving their tensile strength.

Chemical Properties and Corrosion Resistance

Aluminum exhibits a standard potential of 1.67 volts and is highly reactive with oxygen, forming a strong, dense oxide film. This attribute gives it good corrosion resistance in ordinary atmospheres and clean water. However, it’s susceptible to galvanic corrosion when in contact with metals like steel and corrodes in the presence of alkaline materials like concrete, cement mortar, and lime. In humid environments, contact with wood and soil can also lead to corrosion, necessitating appropriate anti-corrosion treatments.

Production Methods of Aluminum Alloys

Aluminum alloys are categorized into cast and deformed types based on their production methods. Cast aluminum alloys are rolled into plates, foils, and strips, and extruded into various complex shapes, making them a staple in the construction industry. Deformed aluminum alloys, including rust-proof, hard, super-hard, and special aluminum, are tailored for specific properties and uses in construction.

Functional Purposes and Advantages

Aluminum and its alloys feature a volume density about one-third of steel, with specific strength (strength-to-weight ratio) that can match or exceed structural steel. Their ease of processing into various shapes makes them adaptable to different construction techniques, offering economical and reasonable options for building structures. The use of aluminum alloys not only reduces the weight and material cost of buildings but also eases transportation and installation workloads, accelerating construction progress. This is especially beneficial in earthquake zones, mountainous areas, and remote locations.


Aluminum, with its multifaceted advantages, plays a pivotal role in construction and design. Its ability to combine lightweight properties with high strength and adaptability makes it an ideal choice for innovative and sustainable building projects. The economic and practical impact of aluminum in various applications underscores its value in the modern construction and design landscape.
