How to distinguish between copper wire and aluminum wire, and what is the difference between copper

Copper wire. The density of copper wire is, pure copper.

There are two kinds of products: smelted products and processed products, among which copper wire has strong conductivity, and copper wire is widely used in the manufacture of cables and wires; Copper wire has good thermal conductivity and is commonly used to manufacture aeronautical instruments, compasses and other magnetic instruments that need to be protected from magnetic interference. But copper wire also has its disadvantage, which is the high cost.

Aluminum wire. The density of aluminum wire is that aluminum wire can be used to make aluminum alloys and willow nails.

Because aluminum wire has the advantage of light weight, it is widely used in aircraft structures, missile structures, and propellers.

Originals, etc. Aluminum wire is a linear material made of aluminum, so it has a special characteristic, that is, the cross-section of the aluminum wire is a uniform solid pressure processing product, and the cross-sectional shape of the aluminum wire is a regular shape, such as a circle, a rectangle, and an equilateral triangle.

Wait. However, aluminum wire also has its disadvantages, that is, it is easy to oxidize and has low mechanical strength.

Summary: Copper wire and aluminum wire are actually very easy to distinguish, from the texture of the two can be distinguished, copper wire is more brittle and aluminum wire is more flexible, so the use of the two is very different; Copper wire can be used to make umbrellas, hangers, etc., and aluminum wire can be made into aluminum alloy and willow nails, which is the difference.

Electrician tutorial: The identification method of copper wire and aluminum wire is really simple, and you will know it next time you buy a wire.

Difference Between Copper Wire and Aluminum Wire:

1. **Different, aluminum wire** is much lower than copper wire, normal copper wire ** is twice that of aluminum wire, and copper wire is heavier than aluminum wire.

2. The flexibility is different, the flexibility of copper wire is more excellent, the deformation is simple, and the fatigue resistance is strong, and the aluminum wire is very easy to break when bending.

3. The resistivity is different, the resistivity of copper wire is small, generally smaller than that of aluminum wire, so the power consumption of aluminum wire is relatively large, and the heating situation is serious, which can easily affect the efficiency of electricity consumption.

4. The stability is different, and the aluminum wire is easy to oxidize when it is used, which leads to an increase in resistance, reduces the load capacity of the wire, and leads to the occurrence of safety accidents.

5. The load power is different, the same cross-sectional area of copper wire and aluminum wire, the load power of the general copper wire is larger than that of the aluminum wire, if both are squared, if the aluminum wire can bear 2500 watts, then the copper wire is 3000 watts.

Is it better to have aluminum wire or copper wire Copper wire is better. The reasons are: 1. Load power:

For copper wire and aluminum wire with the same cross-sectional area, the load power of copper wire is greater than that of aluminum wire. 2. Flexibility: copper wire has better flexibility, easy bending, and strong fatigue resistance.

Aluminum wire is comparatively easy to break when bent. 3. Stability: Aluminum wire is very easy to oxidize, so that the resistance becomes larger, the load of the wire is reduced, and safety problems are easy to occur.

However, the stability of the copper core is excellent. 4. Resistivity: The resistivity of copper wire is small, and the resistivity is lower than that of aluminum wire, which leads to a large power consumption loss of aluminum wire and serious heating, which affects the utilization rate of electricity.

Do the math how much it will cost you to renovate your home

In everyone's decoration process, there are always some small parts that are inevitably used, such as wires, water pipes, switches, sockets, etc. And the wire is divided into aluminum core wire and copper core wire, which are different. Therefore, in order to distinguish the relationship between these two kinds of wires, I will explain to you the difference between aluminum core wire and copper core wire today.

1. The load power of the copper core wire is much greater than the load power of the fiber aluminum core wire. For example, if an aluminum core can load 1000 watts, then the copper core wire can load at least 2000 watts. Therefore, when we choose to buy wires, it is best to choose to buy copper core wires, because the load rate of copper core wires is relatively large, and it is safer and more secure to use.

2. Copper core wire and aluminum core wire are relatively softer than aluminum core wire, but the softness I am talking about is not the degree of softness and hardness, but the flexibility. The copper core wire will be more resistant to bending and will not be easily broken, while the aluminum core wire is very tolerant of being broken when it is bent.

3. The stability of copper core wire and aluminum core wire is also different, in the same environment, aluminum core wire will oxidize faster than copper core wire, which will also increase the resistance in the wire, so that the temperature of the whole wire will rise, thereby reducing the load rate of the wire. The copper core wire will be relatively stable, and it will be less prone to safety problems.

4. Because relatively speaking, copper core wire will be more superior than aluminum core wire, so copper core wire is much more expensive than aluminum core wire. However, no matter how much, it is better to recommend that you buy copper core wire, because in general, the comprehensive performance of copper core wire is relatively good. The wires used in your home must be selected, once there is a problem in the future, it is not only very troublesome to repair, but also easy to cause greater safety problems.

The above is to share with you about the relevant differences between the aluminum core wire and the copper core wire, and I also hope to bring you some help and mention, if you still have any questions about the aluminum core wire and the copper core wire, you can also leave a message to share below, and you will solve problems in time.

Here's how to distinguish it:

1. Distinguish according to weight. Under the same conditions, the motor made of aluminum wire is relatively bulky, and it is heavier than the copper wire motor.

2. The line resistance made of aluminum wire is greater. Use a multimeter to measure the resistance, the large resistance value is the aluminum wire motor, and the small resistance value is the copper wire motor.

3. According to the thickness of the winding. In order to meet the specifications of copper wire motors, the windings of the aluminum wire are increased, and the trunking of the original design of the silicon steel sheet cannot meet the winding embedding. For this reason, the trunking can only be enlarged, and the only way to expand the trunking is to increase the outer diameter and thickness of the stator.

Hello The general identification method on the surface is; Copper wires are marked with the letters BVVB on the outside, while aluminum wires are not.

The packaging on the surface of the copper wire is smooth, because the hardness and strength of the copper wire inside it is placed in a straight row, while the aluminum wire needs to be set up with a strand due to its weak soft strength, and there are traces of the strands from the outer packaging.

These two points can distinguish between copper and aluminum.

Generally speaking, you can't tell by looking at it!

Tell by the strength and material of the wire!

Copper wire is much harder than aluminum wire, and generally speaking, copper wire is golden yellow! And the aluminum wire is white!

Here are some of them!

It doesn't mean to look at it from the rubber, right? It must not be seen, from the section to see the luster of the wire, the aluminum is relatively shallow, but you also know, I have a kind of black technology called "aluminum-clad copper"; If it is not matched, it can also be judged from the specific gravity, and the most direct way is to look at the section.

Copper wire is more difficult to bend than aluminum wire.

Dear, hello, I have inquired for you how to distinguish between copper wire and aluminum wire There are five differences between copper wire and aluminum wire, namely, **, flexibility, resistivity, stability and load power. First of all, the price of aluminum wire is lower than that of copper wire; Secondly, the copper wire is more flexible and easy to bend, but the aluminum wire is less flexible and easy to break after bending; Thirdly, the resistivity of copper wire is smaller than that of aluminum wire, and the heat generation is lighter; Fourth, the copper wire is relatively stable, and the aluminum wire is unstable and easy to oxidize; Finally, at the same power, the load rate of copper wire is greater than that of aluminum wire. Copper wire is expensive, durable, and the copper wire retains its value, has good conductivity and high mechanical strength.

Aluminum wire is cheap but has a relatively short lifespan. It is light in weight and conducts electricity well, but it has low mechanical strength and is easy to oxidize. In life, practical copper wire is used as a wire.

It has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; Good thermal conductivity, often used to manufacture magnetic instruments and meters that must be protected from magnetic interference, such as compasses, aviation instruments, etc.; It has excellent plasticity, easy to be processed by hot pressing and cold pressing, and can be made into copper materials such as tubes, rods, wires, strips, strips, plates, foils, etc. Aluminum wire refers to its longitudinal full length, and the uniform cross-section refers to the metal wire material made of pure aluminum or aluminum alloy as raw material. The product is processed along the center pressure and delivered in rolls.

Cross-sectional shapes include circles, ellipses, squares, rectangles, equilateral triangles, and regular polygons. According to the material, it is divided into pure aluminum wire and alloy aluminum wire. According to the use, it is divided into industrial aluminum wire and process aluminum wire.

One of the simplest ways to distinguish between the two is that the color of the copper wire is purple-red, and the color of the aluminum wire is off-white.

Aluminum wire and copper wire are useful in life. And there are many times when aluminum wire and copper wire can be used together, such as cables, wires, etc., which contain aluminum wire and copper wire. Although aluminum wire and copper wire can be used together, they also have their own unique features.

Aluminum wire can be made of aluminum alloy and willow nails. Copper wire can be used to make umbrellas, hangers, etc., this is the difference. So everything has its own differences, let's learn about the difference between aluminum wire and copper wire!

Aluminum wire. Aluminum wire is a linear material made of aluminum, which is processed under solid pressure along its longitudinal length and uniform cross-section, and delivered in rolls. Cross-sectional shapes are circular, elliptical, square, rectangular, equilateral triangle, and regular polygon.

Features and applications.

Due to its high strength and good fatigue strength, aluminum alloy is widely used in aircraft structures (skin, skeleton, ribs, bulkheads, etc.), rivets, missile structures, propeller elements and other structures.

2024 aluminum alloy with a density of g cm (lb in).

Tensile strength b (mpa) )425

Conditional yield strength (mpa) ) 275

Specimen size: All wall thicknesses.

Note: Longitudinal mechanical properties of pipes at room temperature.

The formability is relatively good in the state, annealing and new quenching state, and the heat treatment strengthening effect is remarkable, but the heat balance treatment process has strict requirements. The corrosion resistance is poor, but it can be effectively protected by cladding with pure aluminum; Cracks are easy to occur during welding, but they can be welded or riveted with a special process.

Copper wire. Copper wire used to refer to telegraphs. Now refers to a metallic material.

Quality. Good electrical conductivity and good thermal conductivity.

Apply. In life, practical copper wire is used as a wire. It has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; It has good thermal conductivity and is commonly used to manufacture magnetic instruments and meters that must be protected from magnetic interference, such as coarse rubber compasses, aviation instruments, etc.; It has excellent plasticity, easy to be processed by hot pressing and cold pressing, and can be made into pipes, rods, wires, strips, strips, slates, foils and other copper materials.

There are two types of pure copper products: smelted products and processed products.

Pros and cons: Copper wire: advantages: strong electrical conductivity, high mechanical strength.

Disadvantages: High cost.

Aluminum wire: advantages: light weight, excellent conductivity, low cost.

Disadvantages: Low mechanical strength, easy oxidation.

The difference between aluminum wire and copper wire is clearly introduced above, and many people think that there is no difference between aluminum wire and copper wire. The effect is the same, in fact, this is not the case, from the texture we know that the aluminum wire is more flexible, and the copper wire is more brittle. Of course, depending on this, their uses are different.
