What is a good material for car wheels? What material are the current car wheels made of?

The wheels of automobiles generally include steel rim wheels, aluminum alloy wheels, magnesium alloy wheels, and carbon fiber composite wheels.

Generally, small cars generally use aluminum alloy wheels. Because compared with steel wheels, aluminum alloy wheels have more energy-saving, comfortable and safe characteristics.

The main characteristics of steel wheels are simple manufacturing process, relatively low cost, and strong resistance to metal fatigue.

The wheel hub of magnesium alloy has high elasticity, good heat dissipation, good shock absorption performance, greater impact load capacity than aluminum alloy, and better corrosion resistance.

Carbon fiber composite wheels have special vibration damping characteristics, which can absorb vibration and reduce noise, have good fatigue resistance, and are easy to repair after damage.

A sister talks about cars: what kind of material is the car wheel hub good? I'll tell you.

The part where the axle is installed in the center of the wheel, which is often referred to as the "rim" or "steel rim".

An important part of the car is composed of wheels, which are divided into two types according to the material: steel wheels and alloy wheels.

1. Steel wheels.

Steel wheels, which are made of steel, are also a relatively common material. The advantage of steel wheels is that the cost is low and the cost is low, but you get what you pay for, its heat dissipation capacity is very poor, and it is easy to rust on rainy days.

2. Aluminum alloy wheels.

The main material of aluminum alloy wheels is aluminum, and manganese, magnesium and other metal materials are added. Compared with steel wheels, it is lighter, so cars with aluminum alloy wheels will be more fuel-efficient.

3. Magnesium alloy wheels.

The main material of magnesium alloy wheels is magnesium, and other metal materials are added. This material is the lightest, so it is now deeply loved by car owners, its shock absorption performance is better, and it is easy to dissipate heat and resist corrosion.

4. Carbon fiber composite wheels.

Carbon fiber composite wheels are made of composite materials, so its cost is relatively high. But on the other hand, it has good noise immunity and is easy to repair even if it is damaged.

Classification of automotive wheels.

The main advantage of steel wheels is that the manufacturing process is simple (generally using the casting process, for example, aluminum alloy wheels are generally produced by low-pressure casting process), the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and strong.

However, the shortcomings of steel wheels are also relatively prominent, that is, the appearance is ugly (it can be said that there is no appearance at all), the weight is large (the same hub steel material is much heavier than the aluminum alloy material), the inertia resistance is large, the heat dissipation is also relatively poor, and it is very easy to rust.

Alloy wheels can just make up for such problems, light weight, low inertia resistance, high production accuracy, small deformation when rotating at high speed, small inertia resistance, which is conducive to improving the straight-line driving performance of the car, reducing tire rolling resistance, thereby reducing fuel consumption.

Automobile wheels are commonly made of aluminum and iron, and aluminum is relatively better.

The low-end version is generally a sticker wheel with a plastic hubcap, and the high-end one is an aluminum wheel. It shows perfection, resulting in air leakage, high roundness, large degree of design freedom, and three times the size of iron. In addition to this, there are three advantages:

High level of comfort. Aluminum alloy wheels can also keep the handlebars at the right temperature due to their metal characteristics that absorb vibration and power.

Save on fuel consumption. Due to the weight of aluminum alloy wheels (about 2kg different from aluminum or steel wheels of the same specification), the rotational inertia of the four wheels is reduced, and it is easy to move the tires and has good safety.

For cars traveling at high speeds. Even in the case of long-distance high-speed driving or continuous braking on downhill roads, the car is stable and comfortable, not only can make the tires and brake drums not easy to age at high temperatures, but also the aluminum alloy wheels because of their structural characteristics, due to tire landing friction, braking, etc.

Of course, with the advancement of technology, magnesium alloy wheels and carbon fiber composite wheels have appeared in recent years, and the material is better.

Magnesium alloy wheels.

Magnesium alloy is a metal material that has received extensive attention in the automotive and electronic fields in recent years, and is the lightest structural material currently in use. Due to its low weight (specific gravity of gram cm3) and good mechanical properties, it has already begun to be used in series production in the field of vehicles and electronics.

Carbon fiber composite wheels.

Composite materials are materials with strong vitality that appear in response to the development of modern science and technology. Because the composite material has special vibration damping characteristics, it can absorb vibration and reduce noise, has good fatigue resistance, is easy to repair after damage, and is convenient for overall forming, so it can be used to manufacture automobile body, stressed components, transmission shafts, engine frames and their internal components.

The most on the market are cast aluminum wheels, the high-end ones are forged aluminum wheels, and the cheap ones are steel rims.

Cheap steel rims are better aluminum, and they are basically alloy materials.

According to the material, the wheel hub can be divided into two categories: steel wheels and alloy wheels. The advantages of the wheel hub are simple manufacturing process, relatively low cost, strong resistance to metal fatigue, etc., and the disadvantages are large weight, large inertia resistance, poor heat dissipation, etc. The advantages of alloy wheels are light weight, high manufacturing precision, high strength, low inertia resistance, strong heat dissipation capacity, good visual effect, etc., and the disadvantages are complex manufacturing process and high cost.

The hub is a barrel-shaped, center-mounted metal part of the tire that supports the tire in the inner rim of the tire.

Steel wheels for trucks, large loads, cheap.

Aluminum alloy or steel is used for ordinary family cars, and the advantages of aluminum alloy wheels are not to be said.

But at the same strength, aluminum alloy is much more expensive than steel, and the non-original aluminum alloy wheels on the market are inferior products, such as copycat oz aluminum alloy wheels for hundreds of pieces!! Genuine oz wheels up to 10,000 yuan! Four forged aluminum alloy wheels cost more than 100,000!

The original wheel hub also needs a thousand!

Inferior wheels will seriously affect safety, and it is easy to break the spokes during driving and cause overturning! Therefore, when writing aluminum alloy wheels, you must not be greedy for cheap, but buy qualified wheels from big brands. The economy does not allow it, or use steel!

1 Steel Wheel The main advantages are the simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. But the disadvantages are also obvious, such as large weight, large inertia resistance, poor heat dissipation and so on.

2 alloy wheels have the advantages of light weight, high manufacturing precision, high strength, small inertia resistance, strong heat dissipation capacity, good visual effect, etc., and the disadvantages are that the manufacturing process is complex and the cost is high.

Truck wheels are cast iron, the same as cast axle housings, ductile iron, disc brake steel wheels alloy wheels.

The alloy material is the best. Because the wheel weight of this material is particularly light, it will be lighter when driving at high speeds, and it is not easy to deform, which can reduce air resistance.

I think the silicone material is better, because the silicone material is very safe, and it is also guaranteed by quality.

Rubber material, most tires are made of rubber, the most important thing is the pattern on it, as well as the thickness of the tire, the skeleton of the tire.

Aluminum alloy wheels are mostly made of aluminum as the basic material, and metal elements such as manganese, magnesium, chromium, and titanium are appropriately added. Compared to iron wheels, the mass is small. Aluminum alloy rims should be light and small steel rims, which can make a great contribution to the fuel saving of the vehicle.

Moreover, the heat dissipation performance is good, which can improve the life of the tire.

A sister talks about cars: what kind of material is the car wheel hub good? I'll tell you.

Hello. The wheels are made of steel and aluminum alloy

There are two types of wheels: iron wheels and aluminum alloys.

Aluminum alloy is divided into forging and casting, as well as iron wheels!

Now forged aluminum alloy wheels are better.
