Anhui Calendered copper foil It is a common copper foil material with good conductivity, thermal conductivity, plasticity and corrosion resistance. In addition to Anhui rolled copper foil, there are other similar materials. Next, I will introduce several common copper foil materials:
Precision copper foil: Precision copper foil is a kind of copper foil material with high purity (usually above 99.9%) and thin thickness. It is mainly used for high-precision circuit boards, thermal insulation materials, electromagnetic shielding materials, etc. in semiconductor, optoelectronics, telecommunications, electronics and other fields. Precision copper foil has better dimensional stability and flatness, and can provide higher line communication rate and resolution.
Copper nickel foil: copper nickel foil is a composite material formed by rolling copper and nickel in a certain proportion. Copper nickel foil has good conductivity, thermal conductivity, electromagnetic shielding performance, and high corrosion resistance. Therefore, copper nickel foil is often used as electromagnetic shielding materials, welding materials, conductive gaskets, etc. in the fields of aerospace, electronic communication, electronic devices, etc.
High temperature copper foil: High temperature copper foil is a kind of copper foil material that can maintain stability under high temperature environment. It has high melting point and high temperature resistance, and can withstand the current and heat under high temperature environment in high-temperature thermopiles, high-temperature batteries, high-temperature furnaces and other applications. High temperature copper foil is usually pure copper or copper foil containing nickel alloy, and its high temperature resistance is improved through special treatment process.
Copper zinc foil: copper zinc foil is a copper alloy foil material prepared by mixing copper and zinc in a certain proportion. It has excellent electrical conductivity and corrosion resistance, and can be used to prepare electrode materials, battery materials, conductive tape, etc. Copper zinc foil can also be specially treated to increase its dimensional stability and surface smoothness to meet different application requirements.
Cu In Ga Se thin film: Cu In Ga Se thin film is a new material used for thin film solar cells. It is composed of copper, indium, gallium and selenium in a certain proportion, and is prepared into a thin film during the rolling process. Copper indium gallium selenium thin films have high light absorption performance and high solar cell conversion efficiency, so they have broad application prospects in the field of renewable energy.
The above listed materials are similar to Anhui rolled copper foil. They have certain similarities in conductivity, thermal conductivity, plasticity and corrosion resistance, and play an important role in different application fields. With the continuous progress of science and technology and the increasing demand for applications, the research and application of these materials will become more extensive and in-depth.
