What Can the Recycled Copper Be Used For?
Copper and copper alloys have been recycled for hundreds of years. Since the ancient times, man
have learned that if newly mined copper ore was not available, copper objects could be melted and
cast into new objects. During wartime, weapons were made from recycled decorative and
household goods. After the war, they were turned back into non-war related products.

Today, the process of transforming unalloyed copper scrap into new copper products begins with
purchasing copper scrap from a national network of scrap processors and brokers. They are
classified and recycled for different purpose.

No.1 scrap is directly melted and in some case brought to higher purity while molten.Chemical
analysis checks the purity level of the copper when the charge is fully melted, and the molten
copper is deoxidized and cast into an immediate shape(cakes, ingots) for further processing.

No.2 scrap is usually electronically refined to attain the desired purity level. But the scrap material
is perhaps fire refined somewhat, melted and cast into anodes. These anodes are the raw materials
used in cathode production. Copper alloys are also recycled. Alloy recycling is usually
accomplished by melting together batches of scrap of known composition, perhaps along with
virgin material, carefully compounded so that the recycled material has the alloy composition
desired.

For these recycled copper, the most important application is high conductivity wire. Ingot producers and
large captive foundries is another big consumer of
used copper/brass automotive radiators. Although
without data, most ingot manufacturers indicates
that over recent years radiators have accounted for
about 50% of the US production of red and semi-red
brass alloys. Here for radiator recycling, I have to
mention AC radiator recycling machine. It can

easily realize the separation of copper tube and aluminum fin in one or two minutes.
