Aluminum profile application scenarios: innovative applications and trends in multiple industries

New Energy Vehicles: Lightweight and Integrated Application Upgrades
In the new energy vehicle industry, aluminum extrusions continue to expand their application due to their lightweight advantages. Recently, a car company released a new pure electric platform model. Its chassis structure utilizes an integrated design of 7-series aluminum alloy extrusions. Using a "hollow variable-section" process, six traditional components are integrated into a single, monolithic frame, resulting in a 42% weight reduction compared to steel structures while increasing torsional rigidity by 35%. The battery pack housing of this model also utilizes high-strength aluminum extrusions for welded construction. Laser welding enhances sealing performance, meeting IP68 waterproofing requirements and compatibility with 800V high-voltage fast-charging systems.

Industry data indicates that domestic demand for aluminum extrusions for new energy vehicles increased by 28% year-on-year in the first quarter of 2025, with structural components such as battery housings and door anti-collision beams accounting for over 60% of this total. To meet the needs of automotive manufacturers, an aluminum processing company has developed 6082-T6 aluminum profiles with a tensile strength of 380 MPa. Using an in-line quenching process, the company has achieved mass production and is currently supplying these profiles to several leading automakers, with orders increasing by 50% year-over-year.

Photovoltaics and Energy Storage: Structural Support for Green Manufacturing

In the photovoltaic bracket industry, aluminum profiles are gradually replacing traditional steel. A photovoltaic company's "Aluminum Alloy Photovoltaic Tracking Bracket System" utilizes 6061-T6 aluminum profiles. Its profiled cross-section enhances wind load resistance, allowing it to withstand wind speeds of 30 m/s. The bracket's surface undergoes an anodizing treatment, resulting in a salt spray resistance of over 5,000 hours, making it suitable for harsh coastal and high-humidity environments. Its lifespan is extended to over 25 years compared to steel brackets, and it requires no corrosion protection or maintenance, reducing overall costs by 20%. In the energy storage sector, containerized energy storage cabinet frames utilize a modular aluminum profile design. A recent energy storage company released a 1MW/2MWh energy storage product whose cabinet frame is assembled from 16 custom aluminum profiles, making it 30% lighter than a steel frame. The mortise and tenon joint design allows for rapid assembly, increasing on-site installation efficiency by 40%. This solution has been applied to multiple large-scale energy storage power station projects, with orders exceeding 1.2GWh.

Architecture and Home: Intelligent and Customized Development

In the architectural sector, aluminum profiles are experiencing continuous innovation in curtain walls and system windows and doors. A construction company has introduced a "Building Integrated Photovoltaic (BIPV) Aluminum Curtain Wall" that integrates photovoltaic panels with an aluminum profile frame. The profile section features cable channels and heat dissipation slots, ensuring structural stability while increasing photovoltaic panel efficiency by 5%. This system has been deployed in a domestic green building demonstration project, with a total curtain wall area of 8,000 square meters and an estimated annual power generation of over 120,000 kWh.

In the home, the trend toward customized aluminum profiles is evident. A home furnishing brand has launched modular aluminum furniture, combining standard 30×30mm profiles with connectors. Users can design the cabinet structure using an app, and the factory cuts and assembles it to their specifications, reducing production time to just 72 hours. The profiles are powder-coated and available in over 200 colors. They are also removable and recyclable, embracing green consumption principles. Their market share has increased to 8% in the six months since their launch.

Rail Transit: High Strength and Safety

The rail transit sector places stringent demands on the performance of aluminum profiles. Recently, a high-speed rail manufacturer developed a new type of train body aluminum profile for a new urban EMU train. Using a large-section hollow extrusion process, a single profile can reach lengths of up to 12 meters, with a wall thickness accuracy of ±0.3mm. The profiles boast a tensile strength of 350 MPa. Combined with friction stir welding, the vehicle body is 15% lighter than traditional designs while still meeting crash safety requirements. This model has entered trial operation, with mass delivery expected within the year. In urban rail transit, the use of aluminum profiles for subway vehicle interior components has been upgraded. A subway company's newly launched trains feature seat frames made of 6063-T5 aluminum profiles, utilizing a hollowed-out design to reduce weight. The surface also features an antibacterial treatment, achieving a 99% antibacterial rate. Handrails utilize circular-section aluminum profiles with a non-slip coating to enhance passenger safety. This retrofit solution has been implemented on multiple lines.
