Advantages of Xinyu Aluminum Enameled Wire

Talking about the strengths of Enameled aluminum wire and its application field. Aluminum enameled wire has the following advantages DC resistivity: The DC resistivity of the copper clad aluminum wire is about 1.45 times that of the pure copper wire; the resistance phase together, the copper clad aluminum wire component. Outstanding solderability: The copper clad aluminum wire has the same congruence as the pure copper wire because of its concentric coating of pure copper. Brazability, not special treatment like aluminum wire; together, copper clad aluminum wire has a thick copper layer to ensure that when painting. Light weight: The copper clad aluminum wire density is 1/2.5 of the pure copper wire of the same wire diameter, which is very useful for the component of the falling coil. Replacing copper wire with Shenzhou copper-clad aluminum wire can save at least 30% of the cost.

Notes on the use of aluminum enameled wire

aluminum enameled wire is a signal transmission, but it is now a power transmission. It is very simple to question, and the life of its goods will be greatly reduced. In fact, in the use of aluminum enameled wire, pay attention to the oxidation maintenance of the undercut wire to ensure the useful connection between copper and aluminum, can be used for a long time.

There are many areas in which copper-clad aluminum wire and copper-clad aluminum enamel bags cannot be used. However, in fact, many companies use transformers, which is very worrying. The worry of the use of copper clad aluminum wire is 2 points, the self-resistance is higher than that of the cross-section copper, and the temperature rise is doubtful; the easy oxidation of aluminum wire will further increase the wire resistance and avoid oxidation.

The most worrying is the copper and aluminum in the Copper Enameled Wire, the metallurgical connection often said in the industry, the reliability in the long-term application process, in the process of thermal expansion and contraction, copper and aluminum contact can Whether it can withstand testing, there is no real proof in the industry.

Xinyu Enameled Wire Devoted to Enameled Wire Development

For winding custom coils or very finely spaced rework, we always touch the electromagnetic wire. The magnet wire is very, very thin (0.1mm in diameter!) Copper wire, with very thin insulation layer. It is used in a range of electronic products, hacker attacks and applications. These are commonly used for winding transformers, inductors, motors or electromagnetic coils, speakers, hard disk head actuators, electromagnets, pickups, and so on. However, this line is also useful when you must perform PCB repair, wire jump, or direct welding to SMT pads.

This axis is ~11.5 meters ~ 38AWG thick magnetic line, just can do a few projects. We recommend a valve core for each engineer’s workbench. Like all electromagnetic wires, there is a thin layer of enamel insulation. Some people like to take it out with a small flame (a lighter, for example), but we’ve found an easy way to melt a piece of solder into the iron and then immerse it in small pieces for a second. Remove the wires, clean them up and tin them!

The enameled copper wire from is technically just an insulated copper wire coated with a tantalum insulation layer. However, the insulating layer is very thin and heat-resistant. This characteristic makes it very suitable for winding coils because each millimeter is considered important because of their thin thickness. Almost all copper lines are completely insulated, and it is now difficult to find uninsulated copper lines.

The two wires have the same conductivity, but the magnetic copper wire is especially coated with a thin, high heat-absorbing material instead of a copper wire. The thin insulating material helps to make more coils in small areas of motors, transformers, relays, etc., and absorbs heat. The common copper wire is insulated with a thick material and may require more area for more turns, so the winding will not work effectively and will be able to melt the insulation in the heat.

Thick plastic coating can be considered a waste of space to solve this problem, you can try other copper wires with ‘normal’ insulation, but you will soon find that the coil is too big or too small. Xinyu enameled wire devoted to Enameled Aluminum Wire development with all the society and make our efforts to the development of enameled wire.
