The invention provides a magnesium alloy for bicycles, the components and mass fractions of which are as follows: the Mg content is 90-92%, the Al content is 3-5%, the Mn content is 3-3.5%, and the rest is Ca. The beneficial effect of the invention is that adding aluminum element to the material components of the magnesium alloy improves the elastic modulus of the alloy material without affecting the stiffness of the magnesium alloy.
Description
technical field [0001] The invention relates to the field of bicycle frames, in particular to a magnesium alloy for bicycles. Background technique [0002] The frame is the main part of the bicycle, affecting the handling of the bicycle and affecting the durability of the bicycle. There are many kinds of materials for the frame, mainly including steel, aluminum, titanium, and carbon fiber. Among them, magnesium alloy is lower than aluminum alloy and has better shock absorption performance. However, magnesium alloy has the lowest elastic modulus, and the elastic modulus will determine the strength of the rigidity of the material, and have a great influence on the force, elastic deformation and plastic deformation of the bicycle. Contents of the invention [0003] The problem to be solved by the present invention is to provide a magnesium alloy for bicycles. [0004] The technical scheme of the present invention is as follows: a magnesium alloy for bicycles, its component...
