What material is the front fender of a car made of
The main materials for the front fenders of automobiles are plastic, steel and aluminum alloy, which depend on the design of the vehicle model, cost and performance requirements.
Material types and characteristics
Youdaoplaceholder0 plastic material :
Common materials include PP+EPDM, PA+PPO or carbon fiber reinforced plastics. They are 40% to 50% lighter than steel and have cushioning properties when impacted, which can reduce damage.
It is mostly used in economy cars or family vehicles (such as Volkswagen Sagitar and Peugeot 307) to control costs and meet pedestrian safety regulations.
Youdaoplaceholder0 steel material :
It is formed by stamping high-strength steel plates, featuring high strength, mature technology and low cost, but it is relatively heavy.
It is commonly seen in models that emphasize durability (such as the Nissan Sylphy), but complex shapes are more difficult to process.
Youdaoplaceholder0 aluminium alloy material :
The advantages of lightweight are significant, with good corrosion resistance, which can improve handling and fuel economy, but the cost is relatively high.
It is mostly used in mid-to-high-end models (such as Lexus ES and NIO ET5).
Youdaoplaceholder0 Replacing the front fender is not considered a major overhaul , as it is merely an external body panel and does not involve the core functional components of the vehicle, thus having no impact on the overall safety and power performance of the vehicle.
The definition of major overhaul and the nature of replacing the front fender
Automobile major overhauls refer to the comprehensive restoration of core functional components, mainly including three categories:
Youdaoplaceholder0 Overhaul of the engine : Core maintenance involving the power system.
Youdaoplaceholder0 Overhaul of the transmission : affects the vehicle's transmission performance.
Youdaoplaceholder0 overhaul of the chassis suspension : It concerns handling and safety support.
The front fender (also known as the front fender) is a body cover located above the front wheels. It mainly serves for aesthetics and protection, preventing sand and gravel from splashing and reducing wind resistance. Its replacement only involves the disassembly and installation of external covering parts, without the need for complex processes, and it is a minor repair.
Possible impacts and precautions
Youdaoplaceholder0 Vehicle value : Although it does not affect performance, the used car market may drive down prices due to maintenance records.
Youdaoplaceholder0 Special circumstances : If the damage is accompanied by frame deformation or suspension system damage, it may be upgraded to a major overhaul.
The main reason why fenders are not recommended for replacement is that they may affect vehicle driving safety, structural integrity and long-term value. Unless the damage is severe (such as over 70% deformation or through cracks), prioritizing repair is a better choice.
Safety risk
Replacing the fenders may weaken the structural strength of the vehicle body and affect driving stability. The fender, as a body panel, is closely connected to the vehicle body through the original factory laser welding points. Violent removal will permanently damage the strength of the welding points (only reaching 70% of the original factory strength after repair), increasing the risk of driving safety. In addition, improperly installed or substandard fenders may cause increased wind noise, reduced impact resistance, and even lead to loosening or abnormal noises during high-speed driving.
The replacement process requires professional equipment and technology; otherwise, it is easy to cause matching problems.
The new fender may not match the original body structure, causing dimensional deviations or a decline in aerodynamic performance, which can affect fuel economy.
Material differences (such as original factory aluminum/steel vs. secondary factory carbon fiber) may increase the risk of corrosion, and inferior secondary factory parts may even fail the annual inspection.
After replacement, the suspension system needs to be readjusted; otherwise, the handling may be compromised.
