The difference between magnesium alloy and aluminum alloy
1 .Tensile strength description: The frame made of the same volume of magnesium alloy material is not as strong as the frame.
For aluminum alloys, it is necessary to increase the thickness of the material and the pipe length to achieve the strength of the frame, so there is no advantage in comparing the magnesium alloy with the aluminum alloy from the weight point of view.
2 .Anti-fatigue strength description: The durability of the frame made of the same volume of magnesium alloy material is worse than that of the aluminum alloy frame. It is also a fatal flaw in magnesium alloys. As the number of rides increases, the number of stresses is higher, the strength is ficantly reduced, and even the frame life is less than 2-3 years, so professional riders rarely use magnesium alloy frames, if used during competitions, It is also calculated that the mileage is replaced by a discarding form.
3 .Metal Oxidation Description: It is clearly shown on the periodic table that magnesium alloys are more susceptible to oxidative corrosion than aluminum alloys.
4 .Manufacturing cost description: Because magnesium alloy is a lively metal, the manufacturing equipment and environment have higher requirements, resulting in high manufacturing costs. The cost of the bicycle frame produced is far less than that of the aluminum alloy frame.
5 .Specific gravity density Description: Magnesium alloy is lighter than aluminum alloy under the same volume, which is the advantage of magnesium alloy.
6 .Elastic Modulus Description: The rigidity of the frame made of magnesium alloy material is worse than that of the aluminum alloy frame. The frame made of the same thickness and diameter will absorb more pedaling force during the actual ride and affect the riding efficiency.
