What are the advantages of copper-aluminum communication substrates?
The application of copper-aluminum composites can be traced back to the 1960s. At that time, some economically developed European and American countries conducted in-depth research on copper-aluminum materials, applied the research results to daily production, and formulated conductor standards for the application of this material. Copper-clad aluminum is considered to be the third generation of new conductors after copper and aluminum in Europe and the United States. Basically, every country has relevant industry standards. It has now entered the practical stage and is widely used in automation, metallurgy, high and low voltage electrical appliances, construction, metallurgy and other industries. Next, the editor will introduce the advantages of copper-aluminum communication substrates to you.
Copper-aluminum communication substrates are made of copper and aluminum and are made using copper-aluminum composite technology. Therefore, copper-aluminum communication substrates have the characteristics of corrosion resistance and low cost, and are widely used in electronics, automobiles, energy, electricity, petrochemicals, metallurgy, machinery and other industries. As we all know, China is a country with more aluminum and less copper. It is troubled by the problem of overproduction in the aluminum industry and insufficient copper resources. At least 60% of the copper raw materials in industrial production rely on imports. In order to solve the problem of insufficient copper resources in industrial production, copper-aluminum communication substrates and copper-aluminum communication substrates that can replace copper metal have emerged. This is of great significance to alleviate the situation of more aluminum and less copper in my country and eliminate the overcapacity of the aluminum industry. Copper-aluminum communication substrates are one of the high-tech energy-saving conductor materials, inheriting the conductivity of copper and the low density of aluminum.
The specific advantages of copper-aluminum communication substrates are listed as follows:
1. Good conductivity: Copper-aluminum communication substrates with a copper-aluminum volume ratio of 15% or 20% are conductive, and their AC current carrying capacity is 85% of pure copper.
2. Light weight. The density of copper-aluminum communication substrate is only 37% to 40% of pure copper busbar, and the length (volume) of the same weight is only 2 to 2.5 times that of pure copper busbar.
3. Excellent mechanical properties: tensile strength, flexibility and elongation are all very good.
4. Promote the strong combination of copper and aluminum. Under different ambient temperatures, permanent atomic particle bonding is achieved between two different metal materials, and the copper layer (tin-plated layer and zinc layer) is evenly distributed without physical defects.
5. Excellent ductility and reliability: After a special heat treatment process, it has a certain plasticity, which helps to stamp, shear, bend and process products without cracking or separation. In order to improve the corrosion resistance of the material, tin-plating and zinc-plating can be performed on the copper surface.
6. Better selectivity: save copper, greatly reduce production auxiliary costs, green and environmentally friendly, and pollution-free.
Copper-aluminum communication substrate can replace copper busbars and aluminum busbars. Widely used in automation, metallurgy, high and low voltage power, construction, and metallurgical industries. This product adopts foreign advanced bimetallic composite technology, with stable quality and reliable performance. It is a high-tech energy-saving product.
