The application of metals in China has been very extensive, among which the types of metals are different, and their characteristics and applications are also different. So, what is the difference between aluminum alloy and magnesium alloy?

First, what is aluminum alloy?
Aluminum alloy has low density, but the strength is relatively high, close to or more than high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of use is second only to steel. Aluminum alloy is the most widely used non-ferrous metal structural materials in the industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipping and chemical industries.
Second, what is magnesium alloy?
Magnesium alloys are alloys composed of magnesium-based addition of other elements. Its characteristics are: small density (about 1.8g/cm3 magnesium alloy), high strength, large modulus of elasticity, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, good corrosion resistance to organic matter and alkali. Mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors.
What is the difference between aluminum alloy and magnesium alloy processing?
1. The tensile strength is different
The strength of the frame made of the same volume of magnesium alloy material is not as good as that of aluminum alloy, and to achieve frame strength, it is necessary to increase the thickness of the material and the pipe warp, so there is no advantage in comparing magnesium alloy with aluminum alloy from the weight point of view.
2. The fatigue strength is different
The durability of the frame made of magnesium alloy material of the same volume is worse than that of aluminum alloy frame. It is also a fatal disadvantage of magnesium alloys. With the more times of riding, 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, and if they are used during races, they are also replaced in the form of abandonment.
3. The oxidation of metals is different
The periodic table clearly shows that magnesium alloys are more susceptible to oxidative corrosion than aluminum alloys.
4. The manufacturing cost is different
Because magnesium alloy is a reactive metal, 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 aluminum alloy frame.
5. The specific gravity density is different
Under the condition of the same volume, magnesium alloy is lighter than aluminum alloy, which is the advantage of magnesium alloy.
