Project Description

As the skeleton of the entire bicycle, the bicycle frame determines and affects the correctness and comfort of the riding posture to the greatest extent.
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 .Density is one of the key factors that determine the weight of the frame. The lower the density, the lighter the frame can be. However, in addition to weight, the frame must also consider tensile strength, elastic coefficient, etc., so although the density is low, the strength is not enough.
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.
