Various metal materials are used in daily life and during production and processing. For example, we will use copper-clad aluminum as cable and wire, because the conductivity of copper-clad aluminum is very good and meet the needs of wire and cable use. However, the copper clad aluminum wire exposed to oxygen is very easy to oxidize and rust, so what methods can be taken to improve the rust and corrosion of the copper clad aluminum wire as much as possible? In fact, there are still many methods that can be taken. Let me introduce you in this article.
1. Electroplating method to avoid wire corrosion: plating a layer of copper on the joints of the wire butt, but it takes too much time (it takes 40 minutes). However, it is not a big problem in the production line company, because many joints can be electroplated together. Copper plating on the surface of aluminum is difficult.
2. The method of avoiding the corrosion of copper clad aluminum wire is to apply copper color quick-drying paint: dry within two minutes, and the color is appropriate to the copper. This is very convenient for users who use copper-clad aluminum wire. Because the user can cut the wiring at any part, the broken end is exposed to the air, in order to avoid electrochemical corrosion after exposure for a long time, you can immediately apply quick-drying paint on the end. The copper and aluminum of the copper-clad aluminum wire cross-section are directly touched. If there is electrolyte on the surface, there will be electrochemical corrosion. If the copper-clad aluminum wire is placed indoors for a long time and the indoor humidity is not high, electrochemical corrosion will not occur. If it is exposed outdoors, it will not be too severe because the end of the corrosive substance will cover the corrosion appearance. Under the circumstances, significant corrosion will occur.
Advantages of copper clad aluminum enameled wire:
1. DC resistivity: the DC resistivity of copper clad aluminum wire is about 1.5 times that of pure copper wire; when the resistance value is the same, the weight of copper clad aluminum wire is about 1/2 of that of pure copper wire.
2. Good solderability: copper clad aluminum wire is concentrically coated with a layer of pure copper, so it has the same solderability as pure copper wire, without special treatment like aluminum wire.
3. Light weight: The density of copper clad aluminum wire is 1/3 of that of pure copper wire of the same wire diameter, which is very useful for reducing the weight of cables and coils.
The application of copper-clad aluminum wire is still relatively wide, and it has played a great role in power transmission and conduction. I believe that the progress of processing technology will reflect more uses of copper-clad aluminum wire. Tinned copper clad aluminum wire is also a kind of metal material, with similar uses and functions, you can understand it if you have the opportunity.
