How to make copper foil in industry?
There are two common methods for manufacturing copper foil in industry Electrodeposition and calendering
1. Electro decomposition
For preparing copper electrolyte for electrodeposition, high-grade copper must be soluble in acid The electrolyte solution is fed into a rotating, partially submerged, charged drum These drums are electrodeposited with a thin layer of copper Another name for this process is electroplating
In the manufacturing process of electrodeposited copper, copper foil is deposited from copper solution on a rotating titanium drum connected to a DC voltage source The anode is immersed in the copper electrolyte, while the cathode is connected to the drum The drum rotates very slowly and copper deposits on it when an electric field is generated The copper surface on one side of the drum is smooth, but the other side is rough
The drum speed becomes slower and the copper becomes thicker Copper is drawn in and deposited on the cathode surface of the titanium drum The sanded surface and roller surface of copper foil are treated repeatedly, making copper suitable for production
2. Manufacturing of copper foil by rolling process
Rolling equipment There are three types of hot rolling mills, cold rolling mills, and foil mills
The process starts with hot rolling copper ingots, heating to 750 C. Then, the thickness is reduced by repeated reverse hot rolling
Before the first cold rolling, mill to remove the oxide scale produced by heat treatment
The thickness of the sheet is reduced to about 4 mm during cold rolling, and the coil is created from the sheet After this process, these coils are again cold rolled by the foil mill to obtain the required thickness of copper foil
Benefits of copper foil

Copper Foil Production Process
The manufacturing of copper foil is a high-end industry in which copper is electrodeposited from an electrolyte onto a rotating drum. The electric loop is closed again by positioning MMO anodes on opposite sides of the drum. During the process, the copper foil grows on the drum.
Although the specifications and properties of electrolytic copper foil can vary with each manufacturer, the process remains essentially the same. Generally, all foil manufacturers dissolve electrolytic copper or waste copper wire – with the same purity electrolytic copper used as the raw material – in sulfuric acid to produce an aqueous solution of copper sulfate. After that, by taking the metal roller as the cathode, the metallic copper is electrodeposited on the surface of the cathodic roller continuously through electrolytic reaction. It is peeled from the cathodic roller continuously at the same time. This process is known as the foil producing and electrolysis process.
The stripped side (smooth side) from the cathode is the one visible on the surface of the laminated board or PCB, and the reverse side (commonly known as the rough side) is the one that is subject to a series of surface treatments and is bonded with resin in the PCB. The double-sided copper foil is formed by controlling the dose of organic additives in electrolyte in the process of producing copper foil for lithium battery.

Copper Sheet
Copper sheet is a very workable and malleable form of metal, high in electrical and thermal conductivity, and provides excellent corrosion resistance. A beautiful and versatile metal, copper has been utilized for thousands of years. Historically, it served as a favorite choice in making tools, vessels, and sculptures. Copper is also known for its beautiful patinas. When exposed, unsealed, to an outdoor environment, copper begins to oxidize. This exposure creates beautiful color variations in the form of a patina. The coloring of the patina will change and develop character over time while serving to protect the metal from deterioration. People will also create a patina quickly with the use of chemical mixtures that speed the process up and allow a patina to develop without outdoor exposure. Copper sheets can also be hammered, tooled, or embossed for added texture and decorative or functional appeal and come in many thicknesses from very thin copper foil to thick copper plate. It also comes in many alloys that blend other metals with copper. At Grand Copper, we sell pure copper -C110 (other alloys and tempers available upon request). This high purity provides the premium quality needed for projects and applications in a wide range of industries and uses. We take pride in providing the best material.

Copper Coils
It may seem that a copper coil is a simple piece of coiled wire that can be wound and put to use. As with any form of industrial product, copper coils have to be precisely engineered to fit an application. The winding process has to be completed with precision to ensure the proper distance between the wires and the diameter of the opening.
Each product that uses copper coils requires that a certain number of turns be made to provide the correct amount of resistance. Inaccurate calculations can lead to inefficiency and possible failure of the coil or device. For this reason, the engineers at Metal Associates guarantee that they have closely examined the specification of an application such that the diameter, spacing, wire thickness, and number of turns exactly matches the design of the product where the copper coil will be used.
