Project Description

The frame material has evolved from the earliest chromium-molybdenum steel to aluminum alloy, and then the use of composite materials such as carbon fiber. Others include scandium alloys, magnesium alloys, titanium alloys, etc. The industry continues to develop new material formulas to improve pipe fittings and structural design capabilities And innovative processing technology, just to make the frame lighter, stronger, more comfortable and more streamlined and beautiful. Density is one of the key factors that determine the weight of the frame. The lower the density, the lighter the frame can be.

The density of chromium molybdenum steel is 7.9, aluminum alloy is 2.6-2.9, titanium 4.5, titanium alloy 4.3-5.1, carbon fiber composite It can be seen that the density of chromium-molybdenum steel is the highest and that of carbon fiber composite is the lowest. Currently, bicycle frames can be made of the following materials: steel, aluminum alloy, titanium alloy, magnesium alloy, scandium alloy, carbon fiber, etc. The general market frame mainly includes steel, aluminum alloy, titanium alloy, and carbon fiber. . Scandium alloys and magnesium alloys are recent emerging materials and are relatively rare.
