Disclosed is a busbar used for a new energy automobile. The busbar is characterized in that the thickness of the busbar is less than or equal to 12.5mm; the sectional area of the busbar is less than or equal to 38 cubic centimeters; the strength of extension b of the busbar is greater than or equal to 200Mpa; the yield strength, which is p 0.2, of the busbar is greater than or equal to 150Mpa; and the elongation, which is 5, of the busbar is greater than or equal to 15%. The strength of extension and the yield strength of the busbar can satisfy the bending and tensile property of stamping, and the hardness of the automatic structural member; and meanwhile, the busbar has relatively high conductivity, and can satisfy electric power connection and transmission requirements. 种用于新能源汽车的母排，其特征在于：所述母排的厚度小于或等于12.5毫米，所述母排的截面积小于或等于38立方厘米，所述母排的抗拉强度即σb大于或等于200Mpa；所述母排的屈服强度即σp0.2大于或等于150 Mpa；所述母排的伸长率即δ5大于或等于15%。本发明的母排的抗拉和屈服强度满足冲压的折弯拉伸性能，以及汽车结构件的强度，同时又有较高的电导率，满足电力的联接和输送。服强度满足冲压的折弯拉伸性能，以及汽车结构件的强度，同时又有较高的电导率，满足电力的联接和输送。
