Advantages of copper-aluminum composite bar
Copper-aluminum composite busbars can also be called copper-clad aluminum busbars, copper-clad aluminum busbars or copper-clad aluminum busbars. As a kind of high-tech energy-saving conductor material, copper-aluminum composite busbars have both the conductivity of copper and the low density characteristics of aluminum.
The application of copper-aluminum composite busbars can be traced back to the 1960s. With the development of the economy, some European and American countries began to study and apply copper-clad aluminum materials and formulate 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. Below, the editor will introduce the advantages of copper-aluminum composite busbars to you.
1. Good conductivity: Copper-aluminum composite bars with a copper-aluminum volume ratio of 15% or 20% can conduct electricity, and their AC current carrying capacity is 85% of pure copper;
2. Light weight: The density of copper-aluminum composite bars is only 37%-40% of pure copper bars, and the length (volume) of the same weight is 2-2.5 times that of pure copper bars;
3. Good mechanical properties: It has good tensile strength, flexibility and elongation;
4. Promote the strong combination of copper and aluminum: Under different ambient temperatures, the two different metal materials achieve inter-atomic bonding, and the copper layer (tin-plated and zinc-plated) is evenly distributed without any physical defects;
5. Good ductility and reliability: After a special heat treatment process, it has a certain plasticity, which is conducive to punching, shearing, bending and processing 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 surface of the copper layer;
6. Better selectivity: Save copper materials, greatly reduce production supporting costs, green and environmentally friendly, and no pollution.
Copper-aluminum composite bar can replace copper and aluminum bars. It is widely used in automation, metallurgy, high and low voltage electrical appliances, construction industry, and metallurgical industry. This product adopts excellent foreign bimetallic composite technology, with stable quality and reliable performance. It is a high-tech energy-saving product.
The above is the introduction to the advantages of copper-aluminum composite bar. I hope this article can help you further understand and know the copper-aluminum composite bar.
