Aluminum alloys are continuously expanding their application fields due to their unique performance advantages.

With many excellent characteristics, the end-use fields of aluminum materials are expanding rapidly. In 2024, the domestic primary aluminum end-use consumption structure shows that aluminum for construction accounts for 24%, aluminum for transportation 23%, aluminum for power electronics 21%, aluminum for packaging 11%, durable consumer goods 10%, and machinery and equipment 8%. As real estate consumption cools down, the proportion of aluminum used in construction decreases year by year, while concepts such as automotive lightweighting, aircraft lightweighting, and energy transition drive the rapid increase in demand for aluminum in automotive and electronic power applications.

Accelerating automotive lightweighting

The penetration rate of aluminum alloys, due to their lightweight, high strength, strong corrosion resistance, excellent thermal conductivity, and high machinability, gives automotive aluminum materials significant advantages in improving traditional vehicle fuel efficiency, extending the range of new energy vehicles, optimizing vehicle handling performance, enhancing structural safety, and improving vehicle aesthetics. Currently, aluminum alloys are widely used in components such as automotive body frames, chassis systems, power systems, electrical systems, and interiors.

Aerospace and military industries

Lightweight alloys are of great significance for the lightweighting process in the aerospace and military industries due to their lightweight, high strength, and strong machinability. Aluminum alloys have strong processing capabilities and are suitable for various processing methods such as welding and pressing. In the aerospace field, aluminum alloys are widely used in structural components of launch vehicles and spacecraft, as well as in key parts like aircraft bulkheads and longerons, enhancing the payload capacity of aircraft.

Stable increase in demand for aluminum in new energy

In power engineering, compared to copper cables, aluminum cables are lower in cost and lighter in weight, which helps improve transmission efficiency and reduce transmission costs. The 14th Five-Year Plan clearly states the need to promote an energy revolution, build a clean, low-carbon, safe, and efficient energy system, and enhance energy supply security. With the surge in demand in fields such as photovoltaics and wind power, and the continuous improvement of smart grid equipment, the demand for aluminum in new energy will rise rapidly.

Building decoration, electronic products, home appliance consumption, and others

The construction sector remains the highest consumption scenario for aluminum. Compared to traditional construction steel, aluminum alloy profiles have a series of advantages such as easy processing, easy coloring, corrosion resistance, and stylish appearance. As the demand for material strength, machinability, and lightweighting in the construction and industrial sectors increases, the use of lightweight alloys in construction is accelerating.

Applications of profiles in construction include doors and windows, curtain walls, brackets, and interior decoration. Energy consumption in the construction sector accounts for about 30% of the total social energy consumption in China. Curtain walls are lightweight wall structures with decorative effects in modern high-rise buildings, serving as non-load-bearing external protective structures with decorative effects. The application of aluminum alloy profiles is concentrated in modern office buildings, hotels, urban commercial complexes, and other commercial real estate and comprehensive venues. Other aluminum applications include electronic products, household appliances, and various daily packaging consumption scenarios. Electronic products have high requirements for material weight, strength, and thermal conductivity, making lightweight alloys ideal materials for manufacturing products like mobile phones, tablets, and laptops. Many electronic products use aluminum alloys as external decorative parts and internal structural components due to their strength, lightness, and excellent heat dissipation.

Aluminum alloys, with their unique performance advantages and continuously expanding application fields, still have a huge market potential. As the domestic and international dual circulation accelerates, high-quality development has become China's primary task. As an important pillar component in the industrial metal field, aluminum alloys play an indispensable role in automotive lightweighting, integrated die-casting, aircraft weight reduction, and lightweight high-strength building materials.
