Forged wheel hub is a type of automotive wheel hub manufactured through forging technology. Compared to traditional cast wheel hubs, it has higher strength, lighter weight, and better performance. The following is a detailed introduction about forged wheel hubs:
1. Characteristics of forging process
High pressure forming: Applying enormous pressure (up to thousands of tons) to aluminum alloy (such as 6061-T6) or magnesium alloy blanks at high temperatures to make the metal grain structure more compact and eliminate internal pores.
CNC precision machining: After forging into an embryo, high-precision modeling and lightweight design are achieved through precise cutting by CNC machine tools.
High material utilization rate: The forging process reduces excess material waste and optimizes the structure of the finished product.
2. Core advantages
Lightweight: 20%~30% lighter than cast wheels of the same size, reducing unsprung mass, improving suspension response and fuel economy.
High strength: With higher impact resistance and fatigue strength, it is suitable for high-performance vehicles or harsh road conditions.
Customization: Flexible design of spoke shape, ET value, J value and other parameters to meet personalized needs.
Good heat dissipation: High metal density and excellent thermal conductivity, which helps to cool down the brake system.
3. Common materials
Aluminum alloy: mainstream choices, such as 6061-T6 (balanced strength and toughness), 7075-T6 (higher strength, used for competitions).
Magnesium alloy: lighter but higher cost, poor corrosion resistance, commonly seen in professional racing cars.
Titanium alloy: extremely rare, used for extreme lightweight requirements.
4. Applicable scenarios
Performance car/modified car: Pursuing handling and acceleration performance.
Track Day/Competition: Strong resistance to high temperatures and deformation.
Luxury car upgrade: balancing aesthetics and performance, such as BBS, HRE and other high-end brands.
5. Precautions for purchasing
Certification standards: Select products that comply with JWL, VIA, T Ü V and other certifications to ensure safety.
Parameter matching: Check if PCD (hole spacing), center hole, ET offset, etc. are compatible with the vehicle model.
Channel reliability: Beware of low-priced "imitation forged" products, as low-quality wheels may have the risk of breakage.
6. Maintenance and lifespan
Cleaning: Avoid strong acid and alkali cleaning agents to prevent corrosion.
Inspection: Regularly check for cracks, deformations, especially after strong impacts.
Refurbishment: Surface scratches can be repainted or brushed, but require professional organization operation.
