In these enzymes copper serves as an electron donor/acceptor by alternating between the redox states Cu(I) and Cu(II) . Other copper proteins such as plastocyanins or azurins act as electron carriers. Depending on the type of coordination of the copper to the protein the redox potential of copper can vary over the range 200 mV to 800 mV.
The first step in this process is to further reduce the size of the copper wire by drawing it through wire draw #2. Operating the same way as wire draw #1 this process makes use of diamond dies to reduce a 10- or 12-awg wire to one 19- 22- 24- or 26-awg wire. After wire drawing the wire is extremely brittle and can easily be fractured if flexed. Since finished copper wire must be flexible the wire

In the following article we will find out more about the manufacturing process of copper wire and tinsel copper wire. Step 1 Drawing Process In this first step of drawing the copper wire manufactures take out EC grade continuous cast copper of minimum 8 mm diameter for kick-start the process of manufacturing the wire. Huge machines are used for this drawing process to carve
Copper can kill viruses and other germs by disrupting the protective layers of the organisms and interfering with its vital processes. A study found that SARS-CoV-2 the virus responsible for the coronavirus pandemic is no longer infectious on copper within 4 hours whereas it can survive on plastic surfaces for 72 hours. Copper has many applications in hospitals and other places where germs
