The lightweight of magnesium alloy bicycles become a development trend
People in the industry believe that it is precisely because magnesium alloy has excellent welding, so the design of the bicycle frame can be designed as much as possible. However, how to reduce production costs and establish a large -scale production line is a big challenge now. The application of magnesium alloy on a bicycle is introduced.
Light quality and lightness of the car body become a development trend
Magnesium alloy has a series of superiority. In the application of bicycles, it has high rigidity, high shock resistance, and high bending. There is nothing harmful to the environment.
It is understood that magnesium and its alloy have the characteristics of low density, high rigidity and higher strength, good damping, and easy recovery. It has been industrialized in the field of aerospace, cars, motorcycles, and bicycles. The amount of magnesium for bicycles has been used as one of the standards for measuring the advanced nature of the car: 5.8 to 23.6 kg of magnesium alloy parts in Europe and the United States uses magnesium alloy parts, and the amount of auto bicycles in my country is less than 10 kg. With the trend of light quality and lightweight in recent years, China's industries have also begun to adopt more and more magnesium alloys.
Gong Xiaoyan, the chairman of the Tianjin Bicycle Industry Association on the front desk, believes that the lightweight and lightweight of the product is the meaning of the development of energy conservation and emission reduction low -carbon products and green industries. From the perspective of innovation requirements for improving low -carbon quality of product weight loss, development and application of new engineering structure materials and high -performance new engineering structure materials and high performance have revolutionary significance for improving product quality and reduction of "carbon footprints". It is reported that the framework of the bicycle is the main load -bearing part of the bicycle and the concentration of the overall weight. If you want to reduce the weight of the bicycle, then this part must be more lightweight and has a material with high comprehensive mechanical properties. Magnesium alloy is one of the good choices.
The mechanical performance parameters of the structural material required for the manufacturing bicycle frame mainly include: density, elastic modulus, stretch length, stretch strength, fracture strength, and toughness. After proper treatment of magnesium alloy, stretching strength and hardness will also be improved accordingly. Through the appropriate method, the magnesium alloy can meet the requirements in terms of strength and elastic modulus. The higher damping coefficient can ensure that the body absorbs part of the energy in the process of being impacted to reduce the impact on the cyclist. At the same time, it can increase the life of the bicycle.
It is understood that it is because of lightweight consideration that many domestic companies have begun to conduct the application experiments of magnesium aluminum alloy on bicycles a few years ago and have achieved major breakthroughs. At present, lightweight metals such as magnesium alloys have begun on the market as frames.
