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.
The manufacturing of copper has changed very little in the past 70 years. Truthfully, it was made in almost the exact same way in the 1930's as it is today, save some minor upgrades. The first step of the process starts with obtaining raw or recycled copper. Methods of acquiring the copper have changed drastically, however.

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.

Comparison of cable runs and data rates between copper and fiber cable. Industrial cabling is available using copper conductors or fiber optic technology. Copper cabling transmits data through twisted pairs of copper wires and fiber cables transmit data using light. Each has its pros and cons.
The process of wire drawing changes material properties due to cold working. The area reduction in small wires is generally 1525 and in larger wires is 2045 . The exact die sequence for a particular job is a function of area reduction, input wire size and output wire size. As the area reduction changes, so does the die sequence.
