The car hub is the part where the axle is installed in the center of the wheel, and it is an important part connecting the brake drum, wheel disc, and half shaft.
Automobile hubs generally use 6061-O aluminum plate, which has excellent processing performance, good corrosion resistance, high toughness, no deformation after processing, easy coloring film, and good oxidation effect. At the same time, it has good heat dissipation, can reduce the weight of the vehicle body, and has good fatigue resistance and wear resistance.
The use of different aluminum alloys in wheel manufacturing lies in the fact that the 5 series alloys have high corrosion resistance and good weldability, and require good formability. Generally, the annealed O state is used, while the use of 6061 aluminum alloys is due to its good processability, high toughness, and processing It is not easily deformed, and the material is dense and defect-free.
Automotive Aluminum Alloy for Car Wheels
Automotive aluminum alloys are commonly used to make car wheels because of their lightweight, high strength, and excellent corrosion resistance. The specific aluminum alloy chosen for an automotive wheel depends on a variety of factors, such as design requirements, performance goals, and cost considerations. The following are some commonly used aluminum alloys for automobile wheels:
-
Aluminum alloy 6xxx series:
- Alloy 6061: This alloy has good strength, excellent machinability, and good corrosion resistance. It is often used on aftermarket wheels due to its versatility and availability.
- Alloy 6063: Known for its good extrudability, this alloy can be used in wheel applications requiring complex designs. It has medium strength and corrosion resistance.
-
Aluminum alloy 7xxx series:
- Alloy 7075: This high-strength aluminum alloy is primarily used for performance or racing wheels. It has an excellent strength-to-weight ratio and good fatigue resistance. However, it can be more expensive compared to other alloys.
-
Aluminum alloy 5xxx series:
- Alloy 5083: Although not as commonly used in automotive wheels as the 6xxx and 7xxx series, alloy 5083 has good strength and corrosion resistance. It can be used in applications requiring higher corrosion resistance, such as wheels for off-road or marine vehicles.
5083 and 6061 are mostly forged in the production of the hub, while 5052 and 5454 are mostly stamped in the rim.
The element content of aluminum alloy in the wheel:
| Alloy/Element | Mg | Cr | Mn | Si |
|---|---|---|---|---|
| 5052 | 2.2-2.8 | 0.15-0.35 | ≤0.1 | ≤0.25 |
| 5454 | 2.4-3.0 | 0.05-0.25 | 0.5-1.0 | ≤0.25 |
| 5083 | 4.0-4.9 | 0.05-0.25 | 0.4-1.0 | ≤0.4 |
| 6061 | 0.8-1.2 | 0.4-0.35 | 0.15 | 0.4-0.8 |
It is worth noting that the choice of aluminum alloy for automotive wheels is influenced by factors such as desired performance characteristics, weight reduction goals, and cost considerations. Manufacturers often employ proprietary alloy compositions or specific heat treatments to optimize wheel performance. Consulting the wheel manufacturer or an automotive specialist can provide more specific advice based on the intended use and requirements of the wheel.
6061 Automotive Aluminum for Car Wheels
6061 aluminum plate belongs to Al-Mg-Si alloy, medium strength, good plasticity, and excellent corrosion resistance, excellent weldability, no tendency of stress corrosion cracking, no deformation after processing, easy coloring film, and good oxidation effect.
The extrusion formability of 6061 o aluminum alloy is good, and the finished product of 6061 after quenching has high hardness and strength, which meets the requirements of lightweight and high strength of the wheel hub. The formed aluminum product has a beautiful appearance and a high recycling rate.
- The heat dissipation is better, which can better maintain the proper temperature of the tire and prolong the service life of the tire.
- Sturdy and durable aluminum alloy wheels have good impact resistance, tension resistance, and heat resistance, and other indicators.
- The 6061-O aluminum plate used for the automobile wheel improves driving comfort.
- The 6061-O state aluminum plate used for automobile wheels improves the stability and safety of driving.
- The 6061-O aluminum plate used for the wheel hub of the car improves the aesthetics of the vehicle and saves fuel when driving normally.
- The operation is brisk, and because of the better roundness, the steering wheel can be better controlled, and the steering is brisk and flexible.
What are the advantages of 6061 aluminum alloy wheels compared with steel wheels?
- The density of 6061 aluminum alloy is small, compared with steel hub, the mass can be reduced by 2/3. According to relevant data, the mass of the vehicle is reduced by 10%, and the fuel efficiency can be increased by 6% to 8%. The application of 6061 aluminum alloy on the wheel hub is of great significance for energy saving, emission reduction, and low-carbon life.
- The heat conduction effect of aluminum alloy is good, and the heat dissipation performance is better than that of steel hub.
- Aluminum alloy is easy to process and form. After corrosion-resistant treatment and painting, the aluminum alloy wheel hub has various colors and is exquisite and beautiful.
- 6061 aluminum alloy has high strength and good safety performance.
The precision of 6061 Automotive Aluminum for Car Wheels is as high as 0.05mm, and the running balance performance is good, which is beneficial to eliminate the phenomenon of general body length and steering wheel vibration.
On average, each aluminum alloy wheel is 2kg lighter than a steel wheel of the same size, and a car can save a whopping 10kg by using 5 wheels. According to the Japanese experiment, every 1 kg weight reduction of a 5-seater car can save about 20L of gasoline a year. A research report published by the American Society of Automotive Engineers pointed out that although aluminum alloy wheels are more expensive than ordinary steel wheels, when each car runs to 20, 000 km, the fuel cost saved is enough to cover the cost.
