Material of the Bike Stand The frame serves as the skeleton of the entire bicycle, which determines and influences the correctness and comfort of the riding posture to the greatest extent. The material of the frame is from the earliest chromium-molybdenum steel, evolved to aluminum alloy, then the use of composite materials such as carbon fiber, and other niobium alloys, magnesium alloys, titanium alloys, etc., the industry continues to develop new material formulations to enhance pipe and structural design capabilities and The innovative processing technology is only to make the frame lighter, stronger, more comfortable and more streamlined and beautiful. Density is one of the key factors determining the weight of the frame. The lower the density, the lighter the frame can be. The density of the chrome molybdenum steel is 7.9, the aluminum alloy is 2.6-2.9, the titanium is 4.5, the titanium alloy is 4.3-5.1, and the carbon fiber is complex. Material 1.6, magnesium alloy 1.7, it can be seen that the highest density of chromium-molybdenum steel, carbon fiber composite minimum. However, in addition to the weight of the frame, the tensile strength, elastic modulus, etc. must also be taken into account. Therefore, although the density is low, the strength is not enough. At present, there are several kinds of materials that can be used to manufacture bicycle frame: steel, aluminum alloy, titanium alloy, magnesium alloy, tantalum alloy, carbon fiber, etc. The main frames on the market are steel, aluminum alloy, titanium alloy, carbon fiber. . Beryllium alloys and magnesium alloys are the latest emerging materials and are relatively rare.
