作为衡量国家基础制造能力的标杆,汽车行业一直是高度集成装配。且由于道路环境的复杂性,对稳固的性能和耐腐蚀性均有严苛的标准。随着新能源车辆的快速崛起,作为新能源汽车的核心部件，电池组件对紧固件的选用提出了新的需求,一方面由于电池的存在,较燃油动力汽车而言，防腐蚀性能更高。
ntroduction: As a benchmark to measure the basic manufacturing capacity of a country. the automobile industry has always been highly integrated assembly. Due to the complexity of the road environment, there are strict standards for stability and corrosion resistance. With the rapid rise of new energy vehicles, as the core component of new energy vehicles, the battery module has new requirements for the selection of fasteners. On the one hand. due to the existence of batteries, the corrosion resistance is higher than that of fuel-powered vehicles; On the other hand, the demand for low-magnetic products will be higher.
