Copper strip is a type of metal foil that is thin in width but long. It is made by rolling copper sheets into thin strips, which are further processed and shaped to meet the required specifications. One of the most outstanding properties of copper strip is its high electrical conductivity, which surpasses most other metals. This characteristic makes it an ideal material for making electrical wires, cables, and connectors.
Another prominent property of copper strip is its superior corrosion resistance. Copper forms a natural oxide layer on its surface, a protective barrier against external elements. This property makes copper strips suitable for use in harsh environments, such as marine, chemical, and industrial settings.
Copper strip is also highly malleable, which means it can be easily shaped into different forms without cracking or breaking. This makes it a preferred material for architectural and decorative applications requiring intricate shapes and designs. Additionally, the copper strip has high tensile strength, which means it can withstand stress and pressure without deforming or breaking.
Annealed copper strips
Annealed copper strips are the most common type of copper strip used for a variety of applications. These strips have been heated to soften the metal before it is cut into various shapes and sizes. The advantage of annealing is that it makes the metal more malleable, allowing for easier bending and forming without cracking or breaking. Annealed copper strips are also relatively inexpensive compared to other types of metal sheets, which makes them popular in diy projects as well as industrial applications.
Tempered copper strips
Tempered or hardened copper strips are heat-treated to make them stronger than regular annealed ones. This process increases their resistance to wear and tear as well as corrosion, making them ideal for outdoor use such as roofing materials or decking boards. Tempered copper strips may be slightly more expensive than annealed ones since they require additional processing steps but can provide superior performance when exposed to high temperatures or harsh weather conditions over time.
Copper foil strips
Copper foil strips are thin pieces of pure metallic copper with one side coated with a thin layer of a plastic film called polyethylene (pe). They come in different thicknesses ranging from 0015 inches up to 003 inches thick depending on the application requirements and can be used for shielding against electromagnetic interference (emi) by providing a barrier between electronic components inside devices like computers, phones and other equipment that emit emi signals into its environment. Copper foil tapes are also available with adhesive backing so they can easily be attached to surfaces where protection from emi is required such as medical imaging machines or any electrical device that requires shielding against electromagnetic radiation.
Making embryos
According to the predetermined production target, different amounts of zinc blocks are added to the waste copper material to prepare copper raw materials of different specifications.
Laboratory test
In order to ensure the production of finished products that are both qualified and economically efficient, the accuracy of the test results is still important. The responsibility of the laboratory is to quickly and accurately analyze the test results based on the copper blocks submitted for inspectiontell the furnace master.
Cut off
The complete copper strip is towed by the suspension rope, placed on a special cutting table, and then cut off by a cutting wheel saw, and then the copper strip surface washing machine smoothes the uneven surface of the copper strip, which is beneficial to the surface of the copper strip processed later flatness and smoothness.
Hot rolling
The cut copper strip is heated at a high temperature of 1000 ℃, and then overheated and rolled into a copper strip with a thickness of about 2.3 cm.
Washing
Each copper block is passed through the preliminary rolling step. Due to the existence of surface impurities, in order to avoid affecting the quality of the finished product, it must go through the sealing furnace and then go through the washing process. The washing area is divided into two pools according to the acidity. High concentration is 6-8 degrees, low concentration is 3-5 degrees. Among them, the middle red patches on the surface of the copper strip can be washed away by the acid in the washing pool, while the dark red patches are removed by the fine iron brush during washing. The copper strip after this series of treatments obviously shines the inherent gloss of copper itself. Similarly, there are still red plaques and red plaques during the rolling process, so we need to repeat the washing step again. During the washing, the acidity in the pool should be checked regularly, and the acid should be added in time to avoid the acid content being too low, resulting in insufficient washing.
Rolling the plate
The rolling area is divided into 180 rolling and 110 intermediate rolling according to the wheel roll. According to the size of various wheel rollers, the copper strip hot rolled down and forged in the sealing furnace is processed from rough to fine through the above two steps.
