Why are they all aluminum wheels now

**Only a fraction of the steel wheel of the aluminum wheel, the accident of breaking on the highway is zero. **It is an aluminum wheel several times that of steel wheels, covering 100% of highway breaking accidents, and many of them also cause car crashes and deaths.

Aluminum wheels on the road teeth or on the road by stone steel head injury, directly broken is good, spend money to change the wheel, but some are injured and cracked but not visible to the naked eye, and then go to run high-speed wheels centrifugal force, the wheel hub may be broken, the car is destroyed.

You never have to worry about this steel wheel, just build it, bumps and bumps don't get in the way. Even if the steel wheel is not tightened, as long as the wheel does not fall off, it can still run, and it will never break. The five screws of the aluminum alloy wheel are not tightened, resulting in uneven force, and cracks may occur in the center of the hub, and then it may be broken at high speed.

Aluminum has low hardness and poor toughness, and it is far inferior to steel as a wheel hub, and steel has high strength and good toughness. U.S. police cars need to collide because they need to chase illegal vehicles, and people stipulate that police cars are only allowed to use steel wheels. Large trucks and off-road vehicles use steel wheels because steel wheels are durable.

In terms of safety performance, arguably the worst steel wheels are also better than the most expensive aluminum wheels. Although the probability of broken wheels is low, it is a major accident that destroys the car and kills people.

In addition to the appearance of the aluminum wheels are not as beautiful, the performance and safety of all aspects of the steel wheels are the first to kill the aluminum wheels. - It's just that it's really hard to buy a steel wheel car now.

Aluminum wheels are fragile and far more expensive than steel wheels, so why do most cars now have aluminum wheels? Is this advertising? Or is it caused by consumers' love of beauty and not love life (not knowing how to be fooled by advertising)?

The Internet is full of articles advocating aluminum wheels and slandering steel wheels, these advertisements and articles are really trying to make money!

First of all, the aluminum alloy material is lower than the steel density, under the premise of ensuring the same strength, the aluminum alloy wheel can meet the lightweight needs, in addition, the aluminum alloy is more beautiful than just now, and more different styles can be designed, and the hollow part is also more than the steel wheel, which is conducive to the heat dissipation of the brake, in addition to the cost will be higher than the steel wheel, basically a little more, from the perspective of reducing costs, the steel wheel is mostly used in some household economic models with low configuration models.

Regarding the landlord's concern about "how about aluminum alloy wheels?" "Here's my personal opinion:

Aluminum alloy wheels are still good, and the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels. Advantages of aluminum alloy wheels:

1. Compared with steel automobile wheels, the advantages of aluminum alloy wheels are more obvious: the density is small, about 1 3 of steel, which means that the use of aluminum alloy wheels of the same volume will be lighter than steel wheels 2 3, statistics show that the quality of the car is reduced by 10%, and the fuel efficiency can be increased by 6% 8%, so the promotion of aluminum alloy wheels is of great significance for energy conservation and emission reduction, and low-carbon life;

2. The thermal conductivity of aluminum is high, while the thermal conductivity of steel is low, so under the conditions of Tongqing Turbulence, the heat dissipation performance of aluminum alloy wheels is better than that of steel wheels;

3. Fashionable and beautiful, aluminum alloy can be aged, the aluminum alloy wheel casting billet without aging treatment has low strength, easy to process and form, and the aluminum alloy wheel after corrosion resistance treatment and coating and coloring is diverse, exquisite and beautiful.
