Gold plated copper foil has the characteristics of high purity and low impurities, and has a high surface smoothness, flat plate shape, and excellent uniformity

The metal material with the highest copper content is called pure copper. Because its surface color is reddish purple, also known as purple copper. Copper has high flexibility and extensibility. Meanwhile, the conductivity and thermal conductivity of copper are also excellent. The purple copper foil produced by Mingjue Metal not only has the characteristics of high purity and low impurities, but also has a high surface smoothness, flat plate shape, and excellent uniformity. Suitable for use in electrical and thermal conductionelectromagnetic shielding materialThe rolled purple copper foil of Mingjue Metal also has good processability and is easy to form and laminate. Due to the spherical structure of rolled copper foil, annealing process can be used to control its soft and hard states, making it more suitable for diverse terminal applications. Mingjue Metal can also produce products of different thicknesses and widths according to customer needs, thereby reducing production costs and improving processing efficiency.

Usage: Can be used for small transformers, flexible connections, copper-clad laminates, copper foil tapes, geothermal films, building decorations, etc.

Purple copper foil is a relatively pure type of copper, which can generally be approximated as pure copper. It has good conductivity and plasticity, but weaker strength and hardness. Copper has excellent thermal conductivity, ductility, and corrosion resistance. The trace impurities in copper have a serious impact on its conductivity and thermal conductivity. Among them, titanium, phosphorus, iron, silicon, etc. reduce conductivity, while cadmium, zinc, etc. have little effect. The solid solubility of oxygen, sulfur, selenium, tellurium, etc. in copper is very low, and they can form brittle compounds with copper, which has little effect on conductivity but can reduce processing plasticity.

Copper has good corrosion resistance in the atmosphere, seawater, certain non oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions, and various organic acids (acetic acid, citric acid), and is used in the chemical industry. In addition, copper has good weldability and can be processed into various semi-finished and finished products through cold and hot plastic processing. In the 1970s, the production of purple copper exceeded the total production of other types of copper alloys.

Purple copper foil (copper content ≥ 99.999%)

Copper foil soft connection process: Copper foil soft connection uses 0.1 copper foil as the raw material, and the raw material is cut according to the design requirements of the drawing. It is necessary to label whether the nickel sheet is pasted on the entire product or locally on the contact surface at both ends. The cut raw material is installed according to the design requirements of the drawing (load current), and the part of the workpiece that needs to be welded is placed on the corresponding mold of the welding machine according to the installation requirements. The working contact surface of the workpiece is integrated and formed by high temperature and pressure

1. Plays an auxiliary role in heat dissipation.

2. It can avoid operational accidents caused by earthquakes, displacements, etc. in the surrounding environment.

3. Absorb a large amount of noise and vibration generated during the operation of electrical equipment.

4. Make the conductive connection between high current devices more convenient, reliable, and protect related devices from external forces
