What’s the first thing that comes to mind when you think of common uses for copper? However, interestingly enough copper plays a significant role in magnets like Motor arc Magnets. And with the high conductivity of the metal, the reason for this has to do.
Electrical conductivity is the primary driver that differentiates copper from other metals according to the Copper Development Association Inc. In fact in this regard, only silver outperforms it. And copper is the clear cut winner in terms of commercially available metals.
What's more, a high level of thermal conductivity is offered by copper as well. Add to this its fatigue resistance, its ductility, excellent strength, its durability, its machinability and corrosion, its oxidation, and creep, it becomes clear why copper is a preferred metal in magnetic applications.
Of course, all of these aforementioned benefits apply to pure copper. Depend on the other materials that make up the specific alloy, it is important to keep in mind that the actual conductivity of copper alloys.
The Copper Development Association warns, to choose from, there are hundreds of copper alloy strip metals and as that of iron, some of them have conductivity as low. The Magnet Factory in China is very reliable.
Designed specifically for magnetic uses, it is important to choose a copper alloy for that reason. One such choice is Copper alloy 110. it is readily available as Also known as Electrolytic Tough Pitch (ETP) Copper, alloy 110, fortunately, the marketplace's most common copper. For magnet applications, what makes it so superior is that it is composed of at least 99.9 percent copper.
It is an oxygen bearing copper, which is indicated by the tough pitch aspect of the alloy's name. To lower the impurity levels to total less than 0.03 percent, the copper in the alloy has been electrolytic ally refined at the same time.
As the Copper Alliance explains, " the high conductivity typical of pure copper is there in Commercial electrolytic tough pitch copper (Cu-ETP) because it contains enough oxygen to ensure that residual impurities are present as oxides rather than in solution. They would have a much more adverse effect than they do on conductivity if dissolved in the copper. Motor arc Magnet have strong magnetic field.
Universal for electrical applications, ETP possesses a conductivity rating of 100 percent IACS at a minimum, but most of the product that is sold today contains 101 percent IACS or more. In addition, 0.02 percent to 0.04 percent is its typical oxygen content. At the same time, at 20 degrees Celsius as 397 versus 230 for aluminum, the Copper Alliance lists ETP copper's thermal conductivity.
To high current applications all of this adds up to ETP copper being amenable. Indeed, alloy 110's high conductivity contributes to it being used exclusively in switch gear, transformers, a variety of other electrical applications and magnets. Moreover for most fabricated electrical components and conductors, it is the material of choice.
