High voltage and high current will be the development trend of electric vehicles, and the requirements for the comprehensive strength and conductivity of charging pile materials will be higher.
China's leading high-performance alloy technology provider: A series of high-conductivity and toughness alloy materials developed by NBBW Alloy Technology Corporation. Through the reasonable ratio of copper, nickel, tellurium, chromium and other related materials, it can meet the specific needs of different types of electric vehicle charging piles, and solve the problem of safe and fast charging of electric vehicles with high current.
Such as the copper-nickel-phosphorus alloys in this series. This alloy is a balanced alloy that combines strength, conductivity and machinability. It is especially suitable for high-current terminals and is an ideal material for the receptacle of charging guns.
NBBW R&D personnel also introduced other models in the series to the Hay Think team: "Red copper alloy, oxygen-free copper, tellurium copper alloy, chromium zirconium copper alloy, etc., these products have good thermal conductivity and electrical conductivity, and also meet the safety requirements. Yes. As a localized replacement product, China's mainstream electric vehicle OEMs are currently using it."
According to reports, this series of products can also be used in power battery formation probes, vehicle internal system connectors and other positions. These components also need to meet the challenges posed by high-voltage fast charging.
Take the connector as an example, its main function is to transmit current and signals, so the conductivity of the connector material is very important. At the same time, in order to ensure the reliability of the connector connection, the corresponding material is required to have sufficient strength.
In addition, the influence of the use environment should also be considered. The car must adapt to the high temperature in summer in the south, the cold in winter in the north, and the high-frequency vibration during driving. Therefore, the thermal stress of the material should also be considered. Relaxation and fatigue properties, taking into account material processing properties such as turning, punching and riveting deformation properties.
It is understood that under the current standard, the high-conductivity free-cutting tellurium-copper alloy developed and produced by NBBW has been widely used in electric vehicle charging piles, which can effectively avoid the phenomenon of high temperature spontaneous combustion of charging piles during use, bringing more efficient, The safe charging experience solves the problem of high-current safe and fast charging of new energy vehicles.
As a "leader" in the field of high-performance alloy materials in China, NBBW has a pivotal position in high-end manufacturing. In aerospace, high-speed rail, 5G, semiconductor, new energy vehicles, marine engineering, mold processing and other industrial fields You can see the company's advanced alloy materials.
NBBW has a national enterprise technology center, a national alloy engineering research center, a national postdoctoral research station, a nationally recognized laboratory, a director unit and a member of the technical committee of the International Nonferrous Metals Processing Association (IWCC), China Patent Excellence Award, and provincial patent demonstration. Enterprise and other multiple identities.
