The advantages of copper-clad aluminum wire

Copper-clad aluminum wire refers to an aluminum core wire as the main body, which is coated with a certain proportion of copper layer on the outside. Today I want to talk to you about the advantages of copper-clad aluminum wire.

1. Because the material is not pure copper, so the price is relatively low. In terms of weight, the unit of measurement used for wires is meters rather than weight, so the cost of transportation is more economical.

2. Because the high-frequency signal has the characteristic of "skin effect", the copper-clad aluminum wire has the same conductivity as the pure copper wire when transmitting the high-frequency signal.

3. Copper-clad aluminum wire is lighter in weight and easy to transport and install, so the labor cost is also reduced to a certain extent.

4.Copper-clad aluminum wire has strong plasticity and does not generate insulating oxides like aluminum, which is suitable for processing.

The features of copper-clad aluminum wire

1. Light weight: under the same wire diameter, its density is 1 / 2.5 of pure copper wire, which reduces the weight of the coil. Use copper-clad aluminum enameled wire instead of copper wire to reduce waste of cost.

2. DC resistivity of copper-clad aluminum wire: the copper clad aluminum enameled wire is 1.45 times that of pure copper wire in DC resistivity; so when the resistance is the same, its weight is much lighter than pure copper wire.

3. Good solderability of copper-clad aluminum wire: Because the surface is covered with a layer of pure copper, it has the same solderability as pure copper wire, and does not need special treatment like aluminum wire.

The applications of copper-clad aluminum wire

1. Copper-clad aluminum wire can be used as electromagnetic wire in high-frequency transformers, ordinary transformers, and inductance coils;

2. Can be used as enameled wire in various household motors, automobile motors, fan motors and micro motors;

3. Copper-clad aluminum wire can be used as enameled wire in the rotor coil of micro motor;

4. Used as a coil in audio and optical drives;

5. Can be used as other special electromagnetic wires.

1. Compared with pure copper wire, under the condition of the same weight and diameter, the length of copper clad aluminum wire is longer than that of pure copper wire. This greatly reduces the cost of cable production.

2. Compared with pure copper wire, copper-clad aluminum wire is of little value to thieves because it is difficult to separate the copper coating from the aluminum core wire.

3. The plasticity is relatively strong and it does not generate insulating oxide like aluminum which is convenient for processing.

4. Light weight of copper-clad aluminum wire that easy to install and transport, thereby reducing labor costs.
