Copper foil M1 0,1х80 mm DPRNT is one of the most demanded types of rolled metal products. It is a thin strip with a thickness of 0.02 mm or more, manufactured in accordance with GOSTs and technical standards.
Copper tape has high corrosion resistance, ductility, excellent thermal and electrical conductivity and durability. Sheet copper is resistant to the negative effects of the environment, has excellent properties in relation to aggressive environments.
Copper tape has several parameters:
according to the manufacturing method, it can be cold-rolled and hot-rolled;
according to the state of the metal - soft (M1), semi-soft (M2), hard (M3);
according to operating conditions: tapes in the form of plates, in the form of pipes, of increased length, with a certain indentation depth.
They are used in construction as a roofing material, for solving design problems, used in mechanical engineering and electronics, in the production of capacitors, for winding transformers.
Foil as rolling is a kind of ordinary sheet, however, it should be understood as much thinner sheets, or strips of rolled metals or metal alloys, characterized by very small dimensions in thickness, from about 0.015 to 0.25 mm, depending on the purpose and the method of manufacture used .
In life, we often meet aluminum foil, which we irreplaceably use in everyday life. But, this is not the only existing type of foil, there is also technical aluminum, lead, copper. Each of them has found its own scope depending on the characteristics. For example, lead foil is more often used for tobacco packaging, appliance parts, technical aluminum foil for thermal or waterproofing. This article will focus on copper foil, its production methods and applications.
As a material, copper has been used by people since antiquity. It is found in nature in the form of nuggets, which does not make its extraction very difficult. The use of copper for industrial purposes is characterized by its high ductility, electrical conductivity, thermal conductivity, corrosion resistance, which makes it an indispensable material in the electrical industry. Copper is used to make refrigerator parts, electrical wires, and even works of art.
If we talk about industries in which copper foil is used, then we can notice their diversity. This includes instrumentation, the food industry, and the chemical industry. For example, foil is used to make circuits, heating films for aircraft, cables, antennas, and much more, since the characteristics of the metal make it possible to use the thinnest copper tape in many industries. Also, it is used in residential and industrial construction, without losing its qualities throughout the entire period of operation.
Due to the popularity of this metal, there are a huge number of companies selling it. But, it should be noted that more often the manufacturer adds too many impurities, resulting in a low-quality product. Therefore, when buying copper products, it is necessary to familiarize yourself with the activities of the supplier, his work experience. One of the most popular copper suppliers is the MetPromStar company, which has been selling rolled copper, non-ferrous metals and stainless steel for more than 10 years, with regional offices throughout Russia.
Speaking of copper foil, it is necessary to touch on the method of its production. There are several types of copper foil. According to the type of production, it can be rolled and electrodeposited. Accordingly, they are created on different equipment, differ in manufacturing methods.
Electrodeposited happens:
1) standard,
2) with high plasticity,
3) hot drawn,
4) annealed.
The first type is more often used under the base and is rarely used in its pure form, due to poor flexibility. The other three types differ in the heat treatment of the standard foil, changing its ductility.
Rolled foil is divided into:
1) rolled,
2) low-viscosity cold-rolled,
3) rolled annealed,
4) rolled at low temperature.
For example, during cold rolling, the metal is heated a little so that it is ductile, yielding to pressure, and then it rolls between two wolves to the desired thickness.
Due to the method used, the foil can have different strengths and prices.
Such external characteristics of copper foil as a red tint, glossy, shiny look have found a new scope for its application - interior design, for example, the creation of decorative stained-glass windows on transparent glass. According to this type of use, another type of foil is distinguished - self-adhesive copper foil. It is called self-adhesive, because it is not necessary to apply glue to its surface. But even to buy it, you must know what you are using it for, since it differs in thickness and operating conditions.
One of the disadvantages of copper foil is the appearance of a green tint obtained by prolonged contact with oxygen, but this can bechange by polishing or special varnishing.
Copper foil is sheets or strips up to about 0.25 mm thick. Varieties of material depend on the method of manufacture and purpose. Copper is popular in electrical engineering, for the production of refrigerators, air conditioners and other equipment, for creating decorations in art.
The advantages of copper foil include:
high manufacturability in the production of cables, insulating and other electrical elements;
endures the impact of aggressive environments and frosts;
the foil is waterproof, has a high thermal conductivity, prevents the formation of corrosion;
The material is of good quality at an affordable price.
Due to the wide variety, the buyer can choose the desired density and size of copper foil, taking into account the scope of its application.
Copper foil is produced in accordance with the requirements of GOST. Be sure to ensure that it is smooth, without damage and impurities. Only high-quality material can serve for a long time and with benefit.
Purpose and application
According to the purpose, copper foil is used in various industries. Tapes are available in thickness from 0.04 mm to 6.0 mm, in width from 10 mm to 600 mm and in length from 500 mm.
Self-adhesive copper foil is used:
For the manufacture of heat exchange devices, many types of electrical equipment.
For cable shielding.
In the construction industry, copper foil is used for thermal insulation and finishing work.
The material is often used to create stained glass crafts.
Foil can also be seen in the field of printing, for embossing.
It is forbidden to use copper foil for the manufacture of goods in the food industry! For these purposes, aluminum or steel material is used.
Due to its good merits, copper foil is used in various industries, except for the food industry. In construction, it retains its original qualities throughout the entire period of operation. The material is often used for the production of equipment.
Copper tape production In principle, copper tape is produced in much the same way as plate, but it is worth noting that even more advanced equipment is required to achieve increased accuracy. Unlike a conventional plate, which can be created using hot-rolled technology, it is cold-rolled technology that is needed for the production of a strip - it is through its use that it is possible to achieve the required thickness of the product. How thick should the copper tape be? You will find out about this now. You should pay attention to the fact that both the production and characteristics of different types of copper products may be the same or very similar, but their areas of application may already be very different. Characteristics of Copper Tape Copper tape, also known as copper strip, differs from plate mainly in its thickness. If for a plate a thickness of one millimeter is practically the minimum (mostly plates are much thicker, especially when the final product must be durable, that is, used in business, and not for decoration), then for a tape such a thickness is already a practically acceptable maximum. The fact is that the thickness of the tape is usually about one tenth of a millimeter, sometimes it can even reach five hundredths of a millimeter. That is why copper tape is not supplied in sheets, like plates, but in rolls, as it is rolled up. As for the other parameters, both thermal conductivity and electrical conductivity do not change due to changes in the thickness of the material.
Copper foil production The last material to be considered is copper foil, the thinnest copper used in the industry. However, do not rush to say that you have seen and know it, and also constantly use it. The fact is that food foil, so popular in the household, is most often made of aluminum or steel, but not copper. As far as copper foil is concerned, it can be produced in two ways - the result is either rolled or electrodeposited foil. In the second case, the material turns out to be grainy, so it cannot be used dynamically - such foil is used only for static purposes. As for katana, this foil is much more even, so its dynamic use does not threaten the appearance of cracks. Characteristics of copper foil Copper foil, as mentioned earlier, has all the same properties and characteristics as the previous material options, but differs in its incredibly thin thickness. If it seemed to you that the copper tape is very thin, then you were wrong - in fact, the foil is the thinnest one. With certain processing methods, it is possible to achieve an amazing thickness of only 18 micrometers, and in some cases the result is even more impressive. The use of copper foil Naturally, due to its electrical conductivity and incrediblythin copper foil is very often used in electrical engineering. It can be found in various electronic boards, even the tiniest ones. It is also very common to see copper foil being used for cable shielding, a task far superior to any other material available at the same price point. As mentioned earlier, copper foil is not used in the food industry, as it has much more suitable aluminum and steel alternatives. You can also find copper foil in the construction industry - most often there it is used for thermal insulation. And of course, very often not only copper, but also any other foil is used in printing in order to produce embossing. Naturally, these are not all areas in which such a wonderful product as copper foil can be used. Many thousands of years ago, when there was a copper age on Earth, people did not know how to handle other metals, so they used a simple and common material - copper. For all its shortcomings, it was much better at making and using tools than the stone that was previously used.
