Is the aluminum alloy bicycle good?

Question 1: What about the aluminum frame of mountain bike? Now the mainstream mountain bikes are all made of aluminum, which is light and durable! It is enough to cope with ordinary road conditions! Merida's frames are mostly TFS and HFS. How many years? I think 10 years is no problem as long as it is not specially kneaded!

Question 2: Is the aluminum frame of mountain bike good? First of all, mountain bikes with aluminum frames are good.

The lowest mountain bike is steel frame, while the high-end is high-end materials such as carbon fiber and titanium alloy, and some are aluminum alloy.

The price of mountain bikes with aluminum alloy frames ranges from 1000 to tens of thousands of mountain bikes. Giant's aluxx and aluxx SL frames, in which aluxx is used for ATX6XX and 7XX series models, and SL is used for xtc series models; Merida frame has light aluminum price (Warrior series), TFS (Duke series, some warriors have been decentralized now) and HFS (Challenger series uses technology to be decentralized at the same time). Therefore, the aluminum alloy frame is also divided into high and low ends.

Question 3: Who knows if aluminum alloy bicycles are good? The aluminum alloy body specially made for bicycles is light in weight and relatively strong in strength.

Question 4: Ladies and gentlemen, is the bicycle made of iron or aluminum? Thank you. . . With the progress of material science and processing technology, the heavy "iron horse" has not adapted to the needs of modern life. The use of composite materials makes bicycles a high-tech means of transportation. The following introduces the widely used materials of the front fork of the frame.

Carbon steel:

Iron (Fe)-carbon (C) alloy without any alloying elements is carbon steel, and carbon can improve the strength in steel. The higher the carbon content, the better the strength, but when the carbon content is higher than 0.8%, the higher the carbon content, the more brittle the steel is. Therefore, the frame and front fork are made of medium-low carbon steel with moderate strength, good plasticity and easy processing, and the carbon content is about 0.25%-

Cr-Mo alloy steel:

Steel made by adding one or more total elements to carbon steel is alloy steel, in which molybdenum (Mo) and chromium (Cr) are added, which is called molybdenum-chromium alloy steel.

The role of molybdenum is to improve the strength of steel and prevent temper brittleness.

The function of chromium: corrosion resistance, rust prevention and high temperature oxidation prevention.

The strength of Mo-Cr alloy steel ranks first among alloy steels, and it is easy to reduce the weight by drawing pipes, so it has become the most commonly used material for frame and front fork. At present, the drawing name of Mo-Cr alloy steel is:

Butt joint (primary pumping) or secondary pumping, two pipe wall thicknesses.

Double docking (secondary pumping) or three-dimensional, with three wall thicknesses.

Triple docking, or four dimensions, with four wall thicknesses.

The function of tube drawing is to make the arch bridge with thin side and thick steel tube unchanged in shape strength, lighter in weight and more metallic.

Aluminum alloy:

Aluminum is the most abundant metal on the earth. Its light weight, corrosion resistance and appropriate strength allow scientists to predict that it may replace today's steel in the future. Aluminum and other metals synthesize aluminum alloys, of which copper is the most common. The use of copper in aluminum alloy is similar to that of carbon in steel, but aluminum alloy used for corrosion resistance cannot contain copper. Originally, the characteristic of aluminum is that it is easily oxidized. Fortunately, it has a higher corrosion resistance than copper and iron because oxygen flowers in the air form a very fine film of AI2 O3, which can protect the inside from oxidation. The so-called anodizing treatment can not only produce a faint AI2 O3 film on the surface of aluminum products, but also be beautiful and anti-corrosive. In addition, the surface of aluminum alloy is easy to dye, and a colored film can be grown to get the desired color.

Magnesium alloy:

Magnesium is a very flammable metal. Magnesium alloy is used in photography in the early days, that is, the strong light produced by the burning of magnesium powder. The weight and strength of magnesium alloy are about 2/3 of that of aluminum alloy. Although light, it is not easy to process and fragile. So at present, except for the front fork shell of ROCK-SHOX shock absorber, magnesium alloy is rarely used in general frame.

Titanium alloy:

The reserve of titanium on the earth is the fourth among metals. The strength of titanium and its alloy is only half that of American alloy steel, and its weight and strength are only half that of American alloy steel. Coupled with its superior corrosion resistance, it has become an essential material for military, aviation and aerospace industries. At present, titanium alloy tubes for bicycles have low universality, high melting cost and difficult processing techniques such as welding, so it is difficult to be widely used.

Carbon fiber:

Carbon fiber is a new material with high strength and light weight. Strictly speaking, it is a composite material. It is not made of a single material. Other resins, glass fibers, aluminum alloys, etc. Can be mixed or ground according to their characteristics. It is the lightest frame material at present. Carbon fiber pipe is made of a little bit of fiber thread woven into carbon fiber cloth, and then layers of stirrup pipes are lapped.

At present, the materials that can be used to manufacture bicycle frames are mainly as follows: steel, aluminum alloy, titanium alloy, magnesium alloy, scandium alloy, carbon fiber and so on. Generally, there are steel, aluminum alloy, titanium alloy, carbon fiber and so on. Scandium alloy and magnesium alloy are relatively rare materials that have only recently appeared.

Question 5: Is the mountain bike all aluminum alloy? Aluminum is a material with low elasticity and rigidity, so most aluminum frames are difficult to ride and react quickly. After scandium permeates into aluminum alloy, the hardness of scandium alloy is greatly improved, and the strength-to-weight ratio can be comparable to that of titanium, so it can be used to manufacture ultra-light frames with high performance.

The fatigue strength of aluminum is the lowest among the four materials, and metal fatigue will occur after a long time of use. For ultra-light aluminum frame, because the pipe wall is very thin, it is easy to crack after a long time of use, which is the cause of fatigue failure.

The aluminum frame is light and hard. The weight of high-end aluminum frame is second only to that of carbon frame, but the price is much lower than that of carbon frame. Therefore, if you want to build a high-performance chariot, you might as well choose an aluminum frame.

Question 6: Is the aluminum alloy bicycle easy to use? I hear it's light. Is it true?/You don't say. There is little difference in function between aluminum alloy bicycles and ordinary bicycles, and aluminum alloy is not pure aluminum alloy. In fact, it also contains elements such as titanium and magnesium, but the amount is very small. Aluminum alloy bicycles are indeed lighter than ordinary bicycles, but you should not feel how light they are. After all, making a bicycle still needs quality assurance. As for which aluminum alloy bicycle is good, I dare not say. My neighbor's Sanctus bike is ok. This is a folding bicycle, which can shift gears. I personally like it very much.

Question 7: Is aluminum alloy or high carbon steel better for bicycles? High carbon steel is the legendary iron bicycle-hi-ten.

Of course, aluminum alloy is more durable and lighter.

Generally, aluminum alloy frames are many times more expensive than high carbon steel frames.

Here is a concept that needs to be clarified:

High carbon steel contains more carbon in iron, and its strength will be better than that of ordinary iron frame.

Aluminum alloy is not pure aluminum. If it is a pure aluminum frame, it can't be used as a frame. Aluminum alloy frames are generally heat-treated (T4, T6), and the strength is absolutely guaranteed.

Now the materials are generally divided like this:

Iron frame-aluminum alloy frame-magnesium aluminum alloy-titanium alloy-carbon fiber.

It's hierarchical.

Question 8: Which is better, a stainless steel bicycle or an aluminum alloy bicycle? It depends on the price. Generally speaking, the frame accounts for about 1/5- 1/4 of the price of the whole vehicle (but specific analysis is also needed), that is to say, a car with a price of 1 1,000 yuan will probably have a 200 yuan -250 yuan frame.

If it's a big brand like Giant or Merida, the border around 200 yuan is obviously a little too low, so don't consider the price of aluminum, and the steel frame is more reliable.

More expensive vehicles don't have steel frames, and the quality of aluminum frames with frame prices around 400 yuan or higher is similar, so there is no choice. If the price exceeds 3000 yuan, you can install it yourself. At this time, we can also consider the problems of steel frame and aluminum frame. But now the better steel frames are very expensive, and the steel frames for vehicles with a price of more than 5,000 yuan are more suitable.

If you have two cars under consideration now, I might as well list them for you to compare.

Have a nice trip!

Question 9: What brand is the best aluminum alloy bicycle on the market? Today's bicycles and the earliest bicycles are made of different materials. For example, many frames are made of aluminum alloy, and the earliest ones are made of steel, which is very heavy. Generally speaking, the current trend is to pursue lightweight, and people are looking for lighter materials to make frames with the same strength, including parts. Nicolai Nikolai, Marmot Groundhog, Colnago Plum Blossom, Tyrell Taylor, Looklock, etc. , that is, the top ten brands in the world recently announced by the Bicycle Industry Association, are generally sold online. Check it yourself.

Question 10: Is it better to use high carbon steel or aluminum alloy for mountain bikes? Let's compare it from several aspects:

1, high carbon steel is heavy, but its strength is also high; Aluminum or titanium alloy is light in weight, but strong enough;

(Not even alloy steel under special circumstances)

But lightweight means lighter body and more fuel-efficient (electricity)

Basically, it is the difference between a German car and a Japanese car. Of course, in terms of safety, mountain bikes and cars are not comparable.

2. Aluminum or titanium alloy has better corrosion resistance and longer service life, which is much stronger than high carbon steel.

This also meets the outdoor environmental requirements of mountain bikes.

3, the price, aluminum alloy or titanium alloy is definitely more expensive, this depends on the individual.

The above is for reference. If I had to choose, I would definitely choose aluminum or titanium alloy if my financial ability allows.
