The differences between alloys and aluminum alloys.


The difference between magnesium alloy and aluminum alloy:


1Differences in tensile strength:


After experimental conclusion, if the same area of magnesium alloy material and aluminum alloy material are made into similar frames or other structural components, the strength of magnesium alloy is not as good as that of aluminum alloy.


2Different fatigue strength


As mentioned earlier, making magnesium alloy materials of the same area and aluminum alloy materials into similar frames or other structural components is not as durable as aluminum alloy. This is also a disadvantage that magnesium alloy needs to be improved and improved. In the coming years, this small bottleneck can be solved by magnesium alloy researchers


As more and more white-collar workers become accustomed to cycling more and more frequently, they also pay attention to materials. The increase in cycling frequency also leads to higher occurrences of stress, lower strength, and even a frame life of no more than 2-3 years. Therefore, to meet the needs of some more professional riders, magnesium alloys must break through this bottleneck, This is also a small reason why professional riders do not use magnesium alloy frames. If they are replaced in a discarded form based on mileage calculation during races, it can be seen that aluminum alloy has better fatigue resistance than magnesium alloy.


3Different alloy elements


There are some similarities in the periodic table of elements. Magnesium is more prone to oxidation and corrosion than aluminum, resulting in certain limitations in the range of use of magnesium alloys. This is also because magnesium alloys have not yet promoted popularization like aluminum alloys, and their current applications are only limited to other related industrial fields such as aerospace, automobiles, ships, medical treatment, etc.


4Different manufacturing costs


Magnesium alloy is an active metal, which has very high requirements in manufacturing equipment and environment, resulting in high costs. The price of Bicycle frame produced is lower than that of aluminum alloy frame.


5Different densities


Magnesium alloy with the same area is much lighter than aluminum alloy, which is one-third the weight of aluminum, which is also one of the advantages of magnesium alloy.


6Elastic modulus


The rigidity of a frame made of magnesium alloy is slightly lower than that of an aluminum alloy frame. Frames made of the same thickness and inner diameter of pipes are more likely to absorb a lot of pedal force during actual riding, which affects riding efficiency.


Overall, Jubao magnesium alloy sheet manufacturers believe that both magnesium and aluminum have their own advantages, but relatively speaking, it currently appears that aluminum alloy is superior to magnesium alloy


The advantages are greater and the application fields are also relatively broad. However, with the research and development of magnesium alloy developers, there is a certain degree of price and performance that can be achieved


Improvement of.
