With the intelligent development of the automotive industry, the demand for intelligent driving and autonomous driving systems continues to increase. Intelligent driving systems, including ADAS (Advanced Driver Assistance Systems), automatic parking, and surround-view systems, require high-precision sensors and durable in-vehicle cameras that must operate reliably in harsh environments over extended periods, thereby driving the growing demand for aluminum alloy housings. As a lightweight, high-strength, and corrosion-resistant material, aluminum alloy has become the ideal choice for smart driving cameras and sensors, meeting the automotive industry's stringent requirements for weight reduction, stability, durability, and safety.
