What is the difference between ordinary aluminum alloy and titanium aluminum alloy and magnesium alu

The composition of the aluminum alloy (both referring to the mass fraction) has a great influence on the appearance, thickness and compactness of the film. The film layer of pure aluminum is transparent, glossy, thick and dense. For aluminum-magnesium alloy, when the magnesium content is lower than 3 in the form of solid solution, it has little effect on the quality of the film, and when its content is higher than 3, the alloy has the second phase of MG5A18 precipitation.

It is easy to dissolve when anodizing, which makes the film forming efficiency low, the film layer is thin, and the uniformity and gloss are poor.

It doesn't matter if you give points or not, I'm just happy to help people (you won't want it if you give it to me).

To tell the truth, what titanium magnesium alloys and so on the market are fake! To be precise, it's not fake, it's just that the aluminum alloy adds a little magnesium or titanium or something, and it can't be seen at all!

It is recommended that you buy a cheap, overall sturdy one, there is no need to spend that unjust money, and there is no need to let people cheat!

The three alloys have different properties due to different materials, and the hardness of the three alloys is from high to low: titanium aluminum alloy, magnesium aluminum alloy, aluminum alloy. Therefore, if you want to buy it, depending on the length of time you want to use it, titanium alloy for the long term, and aluminum alloy for the short term.

Summary. Hello, compared with titanium magnesium alloy and aluminum-magnesium alloy, titanium magnesium alloy is better. The titanium-magnesium alloy material can be said to be a strengthened version of aluminum-magnesium alloy, and the corrosion resistance and mechanical properties of titanium-magnesium alloy are better than those of aluminum-magnesium alloy.

The differences between titanium-magnesium alloy and aluminum-magnesium alloy are: 1. The elements contained are different: the main element of titanium-magnesium alloy is titanium, and only a small amount of magnesium is added, while the main element of aluminum-magnesium alloy is aluminum, and a lot of magnesium is added.

2. Different weights: The weight of titanium-magnesium alloy is heavier, while the weight of aluminum-magnesium alloy is only one-third of that of titanium-magnesium alloy. 3. Different performance:

Titanium-magnesium alloys are complicated to produce and have poor wear resistance, while aluminum-magnesium alloys are easier to color and have better wear resistance.

Which is better, titanium-magnesium alloy or aluminum-magnesium alloy.

1. The difference between costs.

Magnesium alloy is a relatively active metal alloy material, and the manufacturing equipment and environment have relatively high requirements, resulting in the cost of this material in the production will be high, and the cost performance of the bicycle frame produced is not as good as the aluminum alloy frame.

2. The weight and density are different.

Under the same volume conditions, magnesium alloy is 3 times lighter than aluminum alloy, which is the advantage of magnesium alloy.

3. The tensile strength is different.

The strength of the frame made of magnesium alloy material of the same volume is far inferior to that of aluminum alloy, and the thickness of the material and the diameter of the pipe must be increased to achieve the strength of the frame, so there is no advantage in comparing magnesium alloy with aluminum alloy from the perspective of weight, and the tensile strength of aluminum alloy will be greater.

Magnesium alloy properties.

Low density, good specific performance, good shock absorption performance, good electrical and thermal conductivity, good process performance, poor corrosion resistance, easy oxidation combustion, and poor heat resistance.

Its processing process, corrosion and mechanical properties have many characteristics: fast heat dissipation, light weight, good rigidity, certain corrosion resistance and dimensional stability, impact resistance, wear resistance, good attenuation performance and easy to use; In addition, it has the characteristics of high thermal and electrical conductivity, non-magnetism, good shielding and non-toxic.

Applications: Magnesium alloys are widely used in portable devices and the automotive industry to achieve the purpose of lightweighting.

Aluminum alloy characteristics.

Alloys based on aluminum with a certain amount of other alloying elements added are one of the light metal materials. In addition to the general characteristics of aluminum, aluminum alloys also have some specific characteristics of alloys due to the different types and quantities of alloying elements.

The density of aluminum alloy is that it has high strength (b is 110 650MPa), the specific strength is close to that of high alloy steel, the specific stiffness exceeds that of steel, it has good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials, and has a wide range of applications in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities.

What is the difference between a magnesium alloy and an aluminum alloy frame? The magnesium alloy is to be molded, and after the mold comes out, it is integrally formed, and there are no solder joints in the whole body. Since it involves molds, his cost is relatively higher, and the entry threshold is higher.

Although magnesium alloy is indeed much more expensive than aluminum alloy, the quality is high and the overall cost performance is not bad.

1. Different tensile strength: The strength of the frame made of magnesium alloy material of the same volume is not as good as that of aluminum alloy, and the thickness of the material and the pipe warp must be increased to achieve the strength of the frame, so there is no advantage in comparing magnesium alloy with aluminum alloy from the perspective of weight, while the tensile strength of aluminum alloy is greater.

2. Different fatigue strength: The durability of the frame made of magnesium alloy material of the same volume is worse than that of the aluminum alloy frame, which is also the fatal disadvantage of magnesium alloy. With the more times you ride, the higher the number of stresses, the strength will be significantly reduced, and even the frame life will not exceed 2-3 years, so professional riders rarely use magnesium alloy frames, if you use them during the race, they are also calculated and replaced in the form of abandonment;It can be seen that the fatigue strength of aluminum alloy is better than that of magnesium alloy.

3. Different oxidation properties of metals: The periodic table clearly shows that magnesium alloys are more likely to be oxidized and corroded than aluminum alloys, so the scope of use of magnesium alloys is also limited.

4. Different manufacturing costs: Because magnesium alloy is a reactive metal, the manufacturing equipment and environment have higher requirements, resulting in high manufacturing costs, and the cost performance of the bicycle frame produced is far less than that of the aluminum alloy frame.

5. Different specific gravity density: Magnesium alloy is lighter than aluminum alloy under the same volume condition, which is the advantage of magnesium alloy.

In fact, if you look at the bicycles on the market, you can find the answer, aluminum alloy cars are everywhere, but magnesium alloy ones are rare. Sometimes the market determines how high or low it is.

Magnesium alloy bicycle aluminum alloy is better than magnesium alloy bike.

Tensile strength shows that the strength of the frame made of magnesium alloy material of the same volume is not as good as that of aluminum alloy, and the thickness of the material and the pipe warp must be increased to achieve the strength of the frame, so from the perspective of weight, the strength of aluminum alloy is better.

With the more times you ride, the higher the number of times the stress occurs, the strength will be significantly reduced, and even the frame life does not exceed 2 to 3 years, so professional riders rarely use magnesium alloy frames.

Because magnesium lease to alloy is a lively metal, so the manufacturing equipment and environment have higher requirements, resulting in high manufacturing costs, the production of bicycle frames are far less cost-effective than aluminum alloy frames, so aluminum alloy bicycles are good.

Bicycle main material information:

Bicycle frames are typically made of carbon fiber, aluminum, titanium, steel, or a combination of these materials (such as the titanium joints and carbon fiber tubes mentioned in the previous article).

These different materials will have different characteristics and will affect the cost, comfort, weight, strength, stiffness, durability and other disadvantages of the frame. However, while materials are important, I would like to reiterate the importance of frame design and manufacturing processes. <>
