●镁合金在自行车车架中的应用金属镁具有重量轻、弹性模量低的特点，已成为一种新型自行车车架材料。目前，台湾的Merida公司用挤压和焊接法制作了镁合金自行车车架，该公司选用的是AZ６１A－F镁合金，该合金是最硬的一种可制管镁合金，在重金属杂质元素得到有效控制的前提下
● Magnesium alloy in the bicycle frame Magnesium metal has the characteristics of light weight, low modulus of elasticity, has become a new bicycle frame material. At present, Merida, Taiwan, manufactures magnesium alloy bicycle frames by extrusion and welding. The company chose AZ61A-F magnesium alloy, which is the hardest kind of ductile magnesium alloy available in heavy metal impurity elements Under the premise of effective control
