Rolled copper foil with high elongation

    Rolled copper foilBasic meaning: foil means very thick. Copper foil is a thick copper product. Copper, like paper, has a thickness expressed in millimeters. Usually between 0.1-0.01, thinner and wider chestnut bridges are difficult to produce. The meaning of heat treatment is to enlarge and shorten copper foil.

Chinese name:

Basic Overview

Combine these two words to understand. The copper block will extend forward and backward under the pressure of the heat treatment machine. Rolling noodles is the same principle. compare withElectrolytic copper foilThe processing technology difficulty of heat-treated copper foil is higher. Copper foil is made by grinding copper with a certain proportion of other metals. Copper foil usually comes in two types: 90 foil and 88 foil, with copper content of 90% and 88%, and a size of 16 * 16cm. Copper foil is the most widely used decorative material. Such as hotels, temples, Buddha statues, golden signboards, ceramic tile mosaics, handicrafts, etc; Copper foil: A type of negative electrolytic material, consisting of two thin, continuous metal foils crystallized on the substrate layer of a circuit board. It serves as the conductor of a PCB. It is easy to adhere to the insulation layer, receive printed protective layer, and form circuit patterns after rusting. Copper mirror test: A type of flux corrosion test that uses a vacuum crystallized film on a glass plate.

Lithium ion battery foil

Targray uses metal foil as the current collector in lithium-ion batteries. Normally, aluminum foil serves as the positive electrode for the cathode current collector and copper foil serves as the negative electrode for the anode current collector. During the battery production process, the anode and cathode slurries are coated onto foils of the same type.

Electrolytic copper foil of (ED)

ED foil is used in high-energy, low-power applications such as lithium-ion batteries for mobile phones, laptops, and consumer electronics products. Targrass suppliers have a leading position in the industry in terms of quality, innovative research and development capabilities for new products, and the ability to customize the characteristics and capabilities of foils according to the requirements of battery assembly customers. I provide a higher level of service and utilize my global distribution to achieve cost-effectivenessBattery foil material.

Characteristics of rolled copper foil:

1. Highly persistent active substance

2. Excellent tensile strength

3. High elongation rate

4. Required thickness range in nm

Copper alloy anode foil

Targray also offers more lithium-ion battery anodesAlloy steel copper anode foilI can provide more special copper alloys and various customer services, such as printed circuit boards, electromagnetic shielding, and rechargeable batteries, with an increasingly wide range of applications.

Advantages of steel aluminum foil:
1. High conductivity to reduce cell resistance
2. Outstanding high-power application areas: transmission systems and power tools
3. Heat resistance: providing more high heat bending strength and toughness
4. Consistent, with a flat surface and no large protrusions
5. Cleanliness of oxides and oils

Product characteristics

    Rolled Copper FoilHas low surface oxygen properties, can adhere to various substrates such as metals, insulation materials, etc., and has a wide temperature range. The main application areas are electromagnetic shielding and anti-static. By placing conductive copper foil on the substrate and combining it with metal substrates, it has excellent conductivity and provides more electromagnetic shielding effects. It can be divided into self-adhesive copper foil, double conductive copper foil, single conductive copper foil, etc. Electronic grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the basic materials in the electronic industry. With the rapid development of the electronic information industry, the use of electronic grade copper foil is increasing. The products are widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, civilian televisions, video recorders, CD players, copiers, telephones, air conditioners, automotive electronic components, game consoles, etc. The demand for electronic grade copper foil, especially high-performance electronic grade copper foil, is increasing in both domestic and international markets. According to professional institutions' predictions, by 2015, the domestic demand for electronic grade copper foil in China will reach 300000 tons, and China will become the world's largest assembly base for printed circuit boards and copper foil. The market for electronic grade copper foil, especially high-performance foil, is bearish.
