Aluminum Winding Wire Has Good Plasticity

February 21, 2020 by xiu weetime  

1. Aluminum Winding Wire(XINYU-ENAMELEDWIRE) has good electrical and thermal conductivity, ranking fourth after silver, copper and gold. Aluminum winding wire has been used in many fields.

2. It has good plasticity and can be processed by cold or hot pressure to make various profiles, such as wires, wires, rods, tubes, etc. This characteristic is related to the face-centred cubic lattice structure of aluminum.

3. Good atmospheric corrosion resistance. Because an extremely dense aluminum oxide film is formed on the surface of the aluminum winding wire, it can effectively isolate the contact between aluminum and oxygen and prevent one-step oxidation of the aluminum surface.

4. Aluminum is very light (its density is 2.698g/cm3), which is about one-third of copper. Aluminum is often used as the basic component of various light structural materials. At present, aluminum alloy materials are widely used in our daily life.

5. Strength variability. The strength of aluminum is very low, but the strength can be greatly improved after cold deformation and work hardening.

January 17, 2020 by xiu weetime  

With the progress of science and technology, different materials are used in many fields. For example, copper-clad aluminum material is a material used by many manufacturers and users. However, people may not know how to choose copper-clad aluminum material. Then let's have a brief understanding of how to choose copper-clad aluminum material. After all, such materials are used in many places. Therefore, copper-clad aluminum material is a very excellent product in both the present and future markets. Let's let the ECCA Manufacturer(XINYU-ENAMELEDWIRE) introduce it below.

1. Advanced cladding welding manufacturing technology: high-quality copper tape is concentrically coated on the outer surface of core wires such as aluminum rods or steel wires, and a firm metallurgical bond between atoms is formed between the copper layer and the core wires. The two different metal materials are combined into an indivisible whole, and can be drawn and annealed like processing a single metal wire; during the drawing process, copper and aluminum are changed in the same proportion, and the volume ratio of the copper layer is kept relatively constant.

2. Unique composite property: the copper-clad aluminum wire has the composite property of copper conductivity and low density of aluminum, while copper-clad aluminum wire combines copper conductivity with high strength of steel. Tin-plated copper-clad steel wire exhibits solderability and vulcanization resistance of tin. Silver-plated copper-clad steel wire improves electrical conductivity, thermal conductivity, corrosion resistance and oxidation resistance, thus having a wide application range.

In general, we have discussed according to the advanced cladding welding manufacturing technology and unique composite properties. I don't know if you have any knowledge about how to choose copper clad aluminum materials for use? With the progress of technology, more and more materials appear around us.

Copper Clad Aluminum Winding Wire's Main Body Is Aluminum Core Wire

January 10, 2020 by xiu weetime  

Copper Clad Aluminum Winding Wire(XINYU-ENAMELEDWIRE) is a wire with aluminum core wires as the main body and coated with a certain amount of copper layer, which can be used as conductors for coaxial cables and wires and cables in electrical equipment. Because the main function of this kind of wire is to transmit signals, the current flowing through it is very small. In particular, high-frequency signal transmission is completely carried out on the outer layer of the conductor, so the copper clad aluminum winding wire can replace copper wires of the same specification.

Compared with pure copper wires, copper clad aluminum winding wire have obvious advantages: first, they are light in weight, convenient for transportation and installation, and can reduce labour costs; Second, it has obvious economic benefits. At the same time, it is almost impossible to separate the pure copper coating from the aluminum core wire, and it can also receive the additional anti-theft effect.

However, the development and popularization of copper clad aluminum winding wire are restricted by the inherent prejudice of people and the disadvantage that copper wires are more corrosive than copper wires. How to prevent the copper clad aluminum winding wire from being corroded has become the key to its popularization and application.

Copper and aluminum in copper clad aluminum winding wire are two metals with different electrode potentials. When copper and aluminum are exposed in the atmosphere on its end face, if the humidity in the atmosphere is relatively high, the end face will absorb water molecules in the air and accumulate into fine water droplets, which combine with sulfur dioxide in the air to form corrosive solution sulfuric acid. Thus, a corrosive battery composed of anode, cathode, electrolyte solution and an electronic circuit is generated. Corrosive cells are short-circuited primary cells that cause damage to metal materials and do no useful work to the outside world. In this corrosive cell, aluminum is corroded due to its low electrode potential.

At present, copper clad aluminum winding wire has been widely used in the cable TV industry, and it has become the standard material for coaxial cable. It is an updated product of copper conductor and has the advantages of reasonable utilization of natural resources, reduction of production cost, the convenience of engineering construction, etc. In China, with the gradual understanding and correct understanding of copper clad aluminum winding wire, the development prospect of copper clad aluminum winding wire will be very broad.

Improving Corrosion Resistance of Copper Clad Aluminum Winding Wire

January 3, 2020 by xiu weetime  

Copper clad aluminum is a kind of metal composite material, which can exert the performance of two metal materials on one wire. Copper Clad Aluminum Winding Wire(XINYU-ENAMELEDWIRE) combines the excellent conductivity of copper with the advantage of light specific gravity of aluminum to form a light conductive material. There is a point of view that if the resistivity of aluminum conductor is larger than that of copper conductor, the energy loss of aluminum metal material used as the conductor of power cable in the transmission process should be larger than that of copper material. According to the national recommended standard, at 20℃, the DC resistance value of a copper conductor section is equivalent to the DC resistance value of aluminum conductor corresponding to the two specifications. In other words, considering the energy loss in the transmission process, a copper conductor power cable can be completely replaced by aluminum conductor cable corresponding to the two specifications, and their current carrying capacity is equivalent.

1. Good electrical conductivity: The electrical performance of copper clad aluminum bar with the copper aluminum volume ratio of 15% or 20% is 85% of that of pure copper compared with copper bar.

2. Lightweight: the density of copper-clad aluminum bars is only 37%-40% of that of pure copper bars, and the length of the same weight is 2-2.5 times that of pure copper bars.

3. Good mechanical properties: good tensile strength, bendability and elongation.

4. Strong copper aluminum bonding: two different metal materials achieve permanent intergranular bonding between atoms in various ambient temperatures, and the copper layer is evenly distributed without any physical defects.

5. Good ductility and reliability: Through special heat treatment process, it has certain plasticity, which is conducive to no cracking and separation of punched, sheared and bent products. In order to improve the corrosion resistance, tin plating and zinc plating can be carried out on the surface of the copper layer.

6. The best selectivity: saving copper materials, greatly reducing the cost of supporting production, environmental protection and no pollution.

How to Strip Lnsulating Layer from Aluminum Magnet Wire

December 27, 2019 by xiu weetime  

Aluminum Magnet Wire(XINYU-ENAMELEDWIRE) is the main raw material for electric machines and household appliances. Especially in recent years, the rapid growth of the power industry and the rapid development of household appliances have brought a wide range of applications to enameled wires, which also put forward higher requirements for aluminum magnet wire. Aluminum magnet wires are put into mass production in the household appliances, instruments and meters industry. First, the insulating layer on the conductive cable should be stripped so that the cable can be processed in the next step. Traditional stripping techniques include mechanical stripping, chemical stripping and hot stamping stripping. However, each method has related problems, such as conductor damage. The processing speed is slow; Low precision; Poor quality. It is well known that manual and semi-automatic mechanical, chemical or hot stamping stripping is difficult to ensure the stripping quality.

However, in the strict manufacturing application field, a nondestructive, high-precision and high-speed wire stripping technology is needed. Traditional stripping methods have their own defects. With the development of science and technology, creative laser has made unremitting efforts to explore and develop laser strippers. Laser wire stripping machine uses laser wire stripping for insulation, which is a new application of laser in material processing. It has the advantages of fast stripping line speed, high precision, accurate control of stripping process and the like, and can selectively and completely strip the nonmetallic insulating layer without being contacted with the metal conductor by light energy.

Reasons for Yellowing of Copper Winding Wire And Solutions

November 29, 2019 by xiu weetime  

In a sense, the manufacturer of Copper Winding Wire(XINYU-ENAMELEDWIRE) is a finishing and assembling industry. Among them, the choice of copper winding wire is particularly important, and if it is slightly careless, it may lead to safety accidents. I would like to share with you some reasons for the yellowing of copper winding wire and the solutions.

The yellowing of copper winding wire usually has the following reasons:

1. The high-temperature transition and high activity of the tin furnace lead to large pinholes in the coating and rapid copper-tin penetration.

2. The tin layer is too thin, copper and tin soak quickly

3. Excessive halogen residue in flux and incomplete pickling of copper surface

4. The packaging time is too fast, the heat is not scattered, and the tin furnace has too many impurities.

5. The quality of copper is not high, and there are too many impurities.

6. The temperature has an effect on the activity of copper atoms, yellowing faster in hot days than on cold days.

These problems can be dealt with in the following ways:

1. Mold diameter>line diameter +0.02 mm;

2. Place it for about 2 hours and then pack it.

3. Purchase good flux and match flux concentration, mainly because flux affects tin plating quality;

4. Choose better oxygen-free copper wire.

With the deepening of the concept of energy conservation and environmental protection from time to time and the expansion of the demand for environmental protection products from time to time, many industries of enameled wire hardware and electrical machinery have long been heading for the category of energy conservation: LED, energy conservation, environmental protection, and thermal insulation materials, energy-saving doors and windows, construction waste disposal and recycling equipment, air-source heat pumps, and other hardware and electrical products with energy conservation and environmental protection effects are supported by policies, with great market potential and expanding market share from time to time.
