1. Application
Copper and aluminum have good electrical and thermal conductivity. They are the main engineering materials for power transmission and heat transfer, and play an important role in industrial production and national economy. China is a big country in aluminum industry and a big country in copper consumption. As China is relatively short of copper resources, rich in aluminum resources and large price difference between copper and aluminum, a variety of copper aluminum composite materials, such as copper clad aluminum cable, ultra thin copper clad aluminium sheet and copper aluminum composite foil, have been developed with aluminum instead of copper. Among them, copper aluminum composite plate has the advantages of high conductivity, high thermal conductivity, low density and corrosion resistance, and is widely used in the conductive, thermal conductivity and decoration industries.
2. Product description
As a new type of composite material, copper aluminum composite plate has excellent performance and has been widely used in machinery, electricity, household goods and electrical appliances, so its research is of great significance. At present, the production methods of copper aluminum composite plates can not completely replace each other because of their different characteristics. They can only develop together and complement each other. Therefore, it is necessary to further study and improve the combination mechanism of various production processes and various process parameters to achieve better performance.
3. Product Features
The so-called layered metal composite material refers to a kind of metal material that combines two kinds of metal materials in layers by taking advantage of their respective performance advantages. Although each layer of metal still maintains its original characteristics, its physical, chemical and mechanical properties are much better than that of a single metal. At present, there are thousands of metal composites in the world, which can be divided into thermal bimetals, expensive and inexpensive composite metals, conductive elastic composite metals, composite metals for packaging thermal control, composite metals for drinking utensils (decoration), coinage composite metals, brazing composite metals, etc. according to their application characteristics, and are widely used in construction, transportation, medical, chemical, daily products and other fields.
4. FAQ
Ultra thin copper clad aluminium sheet is a kind of composite material with a layer of copper plate and strip on one or both sides of aluminum. It not only has the advantages of good conductivity, thermal conductivity, low contact resistance, easy electroplating and beautiful appearance of copper, but also has the characteristics of light weight, excellent heat dissipation and economy of aluminum. It is widely used in the fields of electronics, communications, electrical appliances, power, heat dissipation, automobiles, building decoration, living appliances, etc.
