Product Parameter 

Product Name: Automotive Aluminum alloy Subframe

The product material is A380/ADC12, etc

Product specifications support non-standard customization

Product processing method: Mold design + precision die-casting molding

Surface treatment: anodizing, powder coating, electrophoresis, etc. (optional)

Product Feature And Application

Lightweight design

Compared with traditional steel subframes, it reduces weight by 40% to 50%, effectively improving fuel efficiency or the driving range of electric vehicles.

Lightweight design reduces unsprung mass, optimizing suspension response and vehicle handling.

High-precision one-piece molding

The high-pressure die-casting process enables the one-time formation of complex structures, reduces welding points, and enhances overall rigidity and stability.

The dimensional accuracy reaches ±0.1mm, ensuring seamless compatibility with the chassis system.

Outstanding material performance

It is made of A380/ADC12 aluminum alloy, with tensile strength ≥320MPa, yield strength ≥160MPa, and elongation ≥3%.

It has excellent corrosion resistance and is suitable for harsh environments such as humidity and salt spray.

Structural optimization and safety

Based on CAE simulation and topological optimization design, the layout of reinforcing ribs at key parts has increased the collision energy absorption efficiency by 30%.

It has passed 200,000 fatigue tests and frontal/side impact verification, and complies with international safety standards such as ECE R94.

Environmental protection and recyclability

Aluminum alloy materials are 100% recyclable, and the recycling rate of production waste exceeds 90%, which is in line with the carbon neutrality goal.

Full-dimensional customized services

Supports customization in terms of size, shape, installation hole positions, sensor integration, etc., and is compatible with multiple platforms including fuel, electric and hybrid.

15-day rapid mold opening, full-cycle technical support from small-batch trial production to mass production.

Application scenarios

New energy vehicles: Reduce the weight burden of battery packs and extend the driving range (such as pure electric/hybrid models).

High-end passenger vehicles: Enhance handling and NVH performance (such as sports coupes, luxury SUVs).

Commercial vehicles: Lightweighting reduces fuel consumption under load and extends the lifespan of components (logistics vehicles, light trucks).

Special vehicles: Customized design to meet the special needs of fire engines, unmanned driving chassis, etc.

Modification market: Offering high-performance lightweight upgrade solutions (daily track vehicles, off-road modifications).
