Copper Pure 99.99% Oxygen Free Cu Alloy for JEWELRY CASTING 8" bar. 1 Lb.

Description

ONE POUND BAR. You will receive one pound bar for melting.
To make fine jewelry, only the purest of pure copper is used.
Wire used in both the electronic industry and transmission of electricity through wire must be as close to perfect as you can get it.
It is usually rated at .999 fine.
The only other metal that conducts electricity better than copper is Silver.
We all know how expensive pure silver is so copper become the go-to ingredient.
Copper is extremely difficult to produce for the Jewelry and the electronic industry.
It requires perfection and no room for error.
There can be no air or oxygen in the target.
This is done by
electrolysis
where the
copper
anodes from the
smelter
become positive electrodes and thin, three-foot square sheets of pure
copper
are used as negative electrodes. ... Oxidation occurs at the anode, where
copper
metal is converted to
copper
ions with the release of two electrons.
At the cathode the opposite reaction occurs: copper ions are joined with two electrons to form copper metal. During the migration of metal ions from anode to cathode through the aqueous solution, the impurities drop to the bottom of the electrolysis cell. Some of these impurities are gold, silver, nickel, selenium, tellurium, and platinum which are themselves recovered to be used.
They are then formed into copper bars that are free from oxygen and bubbles.
The copper you are purchasing is the finest copper known in the Industry.
