Achievement:

The battery swap life is >5000 times (3000 times required by the national standard), and it has obtained CATARC durability certification.

30% increase in single-day service capacity and 25% lower cost than steel.

Flying Cars (Global Frontier Market)

Case: Xpeng Huitian flying car battery compartment

Solution: 3.0mm aluminum plate topology optimization design, anti-vibration (frequency 50-2000Hz, acceleration 10g).

Achievement:

The energy density is 300Wh/kg, and it has passed the DO-311 aviation airworthiness standard.

15% lighter and 50% less cost than carbon fiber solutions.

Prospect for future applications
Solid-state battery adaptation:

Development of high-pressure-resistant (≥5V) anodized coating for sulfide solid electrolytes (e.g., Toyota's 2027 mass production plan).

Intelligent Integration:

Embedded fiber optic sensors monitor stress/temperature, and data is transmitted to the BMS (e.g. Tesla CyberTruck 2.0) in real time.

Space-grade lightweighting:

Composite molding with carbon fiber (weight reduction and 20% reduction) for the lunar rover's energy system (radiation resistant 1Mrad).

Closed-loop recycling system:

Blockchain traceability technology enables 100% recycling of aluminum scrap (e.g. BMW i Recycling Plant 2030 Plan).

AutoFrame 5052 aluminum alloy has become the gold standard for battery trays for new energy vehicles with the characteristics of "light as a feather and solid as gold". From luxury coupe to Xpeng's flying car, its performance has been verified by sea, land and air. With breakthroughs in solid-state batteries and space exploration, the material will continue to drive the evolution of energy vehicles into a more efficient, smarter, and more sustainable future.
