Copper clad aluminum magnet wire is a new type of magnet wire that uses copper-clad aluminum material as the inner conductor. Its characteristics are between copper and aluminum. It combines the excellent conductivity of copper and the light weight of aluminum, which can greatly reduce the cost of electrical windings. All are pure copper, which overcomes the shortcomings of aluminum being easy to oxidize, corrode, and difficult to weld.
 


Features:
 
1. DC resistivity: The DC resistivity of copper clad aluminum wire is about 1.45 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; at the same time, copper The aluminum-clad wire has a thick copper layer to ensure that the soldering performance of the product will not be affected when the paint is scraped;
3. Light weight: The density of copper clad aluminum wire is 1/2.5 of pure copper wire of the same wire diameter, which is very effective in reducing the weight of the coil; using Signi Aluminum’s Copper clad aluminum magnet wire to replace copper wire can save at least 30% of the cost.
 
Henan Signi Aluminum has more than 100 sets of advanced equipment such as professional high-speed wire drawing machines, vacuum tube continuous annealing furnaces, and enameling machines. At the same time, the company has introduced direct loss. A series of advanced testing equipment such as instrument, to ensure that the quality of the product is strictly tested before each process and shipment. The company currently produces 500 tons of Copper clad aluminum magnet wire per month.
