Ningbo, Zhejiang: East-West Industrial Collaboration Hatches "Golden Phoenix"
Just after the Spring Festival, in the heavy Industrial Park in Xingren Baling Town, Guizhou, as one of the industrial cooperation projects in the Yangtze River Delta region and the western region, a new production line built by a group in Ningbo has attracted much attention. "This production line will produce a new product called'copper-aluminum eutectic plat', which will be independently developed by our team for more than two years." Xu Yinchang, the person in charge of the enterprise, introduced.

Due to the different physical properties of the two metal materials of copper and aluminum, copper and aluminum cannot be directly used in the air, otherwise electrochemical corrosion will occur; the metal composite interface of the composite material reaches a metallurgical bonding state, and there is no medium in the middle, and electrochemical corrosion will not occur. Therefore, the copper-aluminum composite products produced by our Sanxie Metal have been successfully used on the grounding device of rail transit. The use of special grounding blocks for cloud rail, subway and high-speed rail has solved the problem of copper-aluminum connection between the car body and the electrical system, greatly improving the safe operation capability of rail transit, and the special surface treatment technology can ensure the stable operation of the products during long-term use.

Copper-aluminum composite ground nut is a kind of nut made of bimetal copper-aluminum composite material. It is used for grounding engineering and fasteners in rail transit industry. It is made of a layer of copper and a layer of aluminum through high temperature and high pressure. It has good electrical conductivity and corrosion resistance and is widely used in electrical engineering, construction, railway, highway and other fields.

The aluminum-clad steel grounding block used in the rail transit industry is a composite grounding block composed of aluminum plate and steel core, in which the aluminum plate covers the surface of the steel core to form an "aluminum-clad steel" structure. The advantage of this kind of grounding block is that the aluminum plate can prevent the corrosion of the steel core, and the conductivity of the aluminum plate is better, which can improve the grounding efficiency. In addition, due to the coverage of the aluminum plate, the grounding block is not easy to rust and be affected by the external environment, and has a long service life.

Does the power conductive "copper-aluminum composite plate" deform when heated?
Copper aluminum composite plate is made of copper and aluminum two kinds of metal through a certain process of composite materials. Both copper and aluminum are metals, and metals usually undergo thermal expansion when heated, which is an inherent property of metal materials. Thermal expansion refers to a phenomenon in which the average distance between atoms increases when the temperature of an object increases, resulting in an increase in the volume of the object.

Copper-aluminum transition plate transition row-left and right butt joint structure
The flat butt copper-aluminum transition plate is a transition connector used to connect two metal materials, copper and aluminum. Due to the large differences in physical and chemical properties between copper and aluminum, problems such as electrochemical corrosion and poor contact are easily generated during direct connection. Therefore, a special transition plate is required to achieve a reliable connection between the two.
