Cu - Copper
Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.
Since 8000 BC we are using copper.
As with any consumable, the ultimate goal is to put off replacement for as long as possible. And this means matching the right nozzle with the right application. The type of project, the work piece metal, and the welding mode can all help you start to narrow down your nozzle choices. Using a pulse mode vs. spray or short circuit, for example, will lead to many different options. So will your level of current, heat, access to the weld and the expected amount of spatter
