Soft 0.005Mm 0.01Mm 0.02Mm Copper Charger Sheet C1020 Foil / Coil Copper Foil

The copper foil is of a low surface oxygen characteristics, can be attached to a variety of different substrates such as metal, insulating materials, etc., within a wide temperature range. Mainly used for electromagnetic shielding and antistatic, conductive copper foil on the substrate surface, combined with the metal substrate, has an excellent conductivity and electromagnetic shielding effect.It can be divided into: self-adhesive copper foil, copper foil of the double glue,single copper foil, duplex copper foil.

Properties and chemical composition

Good conductivity and heat conduction. Corrosion resistance and machining properties, can be welded and fiber welding. Contains less impurities that reduce conductivity and thermal conductivity, and trace amounts of oxygen to conductivity. Thermal conductivity and processing performance is not affected, but easy to cause "hydrogen disease", not at high temperature (such as gt; 370°) in reducing atmosphere (annealing. Welding, etc.) and use.

The use of red copper is much more extensive than pure iron, 50% of the copper is purified for pure copper by electrolysis every year, used in the electrical industry. Here said copper, really to be very pure, copper 99.95% or more, a very small amount of impurities, especially phosphorus, arsenic, aluminum, will greatly reduce the conductivity of copper. Oxygen in copper (copper smelting is easy to mix with a small amount of oxygen) has a great impact on conductivity, copper used in the electrical industry must generally be anaerobic copper. In addition, lead, antimony, bismuth and other impurities will make the crystallization of copper can not be combined together, resulting in hot brittle, will also affect the processing of pure copper. This kind of pure copper with high purity is generally refined by electrolysis: the impure copper (coarse copper) as the anode, pure copper as the cathode, and copper sulfate solution as the electrolyte. When the current passes through, the impurity copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. Copper obtained by such refinement; The purity can reach 99.99%. Copper is a relatively pure copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength, hardness is worse

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America. Our best service and excellent quality have led long-term partners in many countries and established continuous business relations with all customers. Our principle is "service first, sales second". Most of the time, we have comprehensive inspection and procurement to control the quality of finished products. We will have a professional inspection team to test each delivery of products.

Since its establishment, in line with the mission of "contributing high-quality products and services to the world" and the core values of "customer first, excellence, coexistence and win-win", we ensure that we can deeply cooperate with all our friends in the field of iron and steel, and win more affirmation and praise from the market and customers with its high-quality products, perfect product team and thoughtful service, I believe tomorrow will be better!
