  • The Effects of Oxidation on Copper | Sciencing

    Apr 17, 2018 · However, copper oxidation produces harmful effects in copper cookware. When the copper cooking surface comes into contact with acidic food (i.e. vinegar, wine), it produces a toxic verdigris, which is poisonous if ingested. Copper electrical wire and copper pipes must be cleaned with acid-free cleaners before soldering takes place.

  • Central Burst - Forums

    The central burst phenomenon is quite rare and generally has to do with the drawing die cone angle. Often it occurs when an operator actually puts a die in backwards. For simplicity, think of it this way: Somewhere between drawing solid wire and breaking the wire, there is a spot where a very rough internal surface tube is drawn.

  • What Is Tinned Copper Wire? | Sciencing

    Apr 17, 2018 · Tinned copper wire is just as conductive as bare copper wire, but the thin layer of tin helps the wire resist corrosion. Tinned copper wire can last up to 10 times longer than its non-tinned counterpart, and because solder is composed primarily of tin, tinned wire is incredibly easy to solder.
