Hemaokang Steel (Shandong) Co., Ltd. is proud to offer the 5754 Aluminum Coil in thicknesses from 1.5mm to 5mm with an annealed (O) temper, specifically engineered for high-performance automotive body panels. As a trusted supplier established in 2025 with an annual export value exceeding US$50 million, we combine advanced manufacturing capabilities with rigorous quality control to deliver coils that meet the demanding requirements of the automotive industry. Our 5754 alloy provides an excellent balance of strength, corrosion resistance, and formability, making it the ideal choice for stamping, deep drawing, and structural components in vehicles.
This product features a fully annealed (O temper) condition, which ensures maximum ductility and minimized springback during forming operations. With a thickness range of 1.5mm to 5mm, it accommodates a wide variety of automotive panel applications, from inner structures to outer skin panels. The coil is processed on state-of-the-art rolling mills and annealing furnaces, guaranteeing consistent mechanical properties across the entire coil length. Backed by our ISO 9001 certification, every coil undergoes strict dimensional, chemical, and mechanical testing before shipment.

Key Features and Benefits
- Superior Formability: The annealed temper (O) provides excellent ductility, allowing complex shapes and deep draws without cracking, ideal for automotive body panels.
- Excellent Corrosion Resistance: 5754 alloy contains magnesium, offering high resistance to atmospheric corrosion and road salt, extending vehicle life.
- Lightweight Strength: Compared to steel, this aluminum coil reduces weight by up to 50%, contributing to fuel efficiency and lower emissions.
- Consistent Mechanical Properties: Our controlled annealing process ensures uniform hardness and elongation across the entire coil, reducing scrap during stamping.
- Weldability & Machinability: 5754 alloy is readily weldable using MIG/TIG processes and can be easily cut, drilled, or formed.
- Customizable Dimensions: We offer slit widths, inner diameters, and specific coil weights to match your production line requirements.
Our 5754 aluminum coil is extensively used in the automotive industry for components such as door panels, hoods, trunk lids, fenders, and structural reinforcements. The combination of high strength-to-weight ratio and excellent fatigue resistance makes it a preferred material for modern electric vehicles (EVs) and lightweight body designs. Additionally, the coil can be supplied with an optional protective film to prevent surface scratches during handling and stamping.
