The Effects of Oxidation on Copper | Sciencing

Apr 17, 2018 · Copper electrical wire and copper pipes must be cleaned with acid-free cleaners before soldering takes place. In addition, care must be taken not to overheat the copper during the soldering process, as excess heat produces copper oxidation, and the solder won't adhere to it. Oxidation also hinders the electrical conductivity of copper wire.

From Ore to Finished Product

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
