Description |
| Copper |
Wrought
101 - 159
Cast
800 - 813
|
Metals which have a designated minimum copper
content of 99.3% or higher. |
| High Copper Alloys |
Wrought
160 - 199
Cast
814 - 832
|
For the wrought products, these are alloys with
designated copper contents less than 99.3% but more than 96% which do not
fall into any other copper alloy group. The cast high copper alloys have
designated copper contents in excess of 94%, to which silver may be added
for special properties.

These alloys contain zinc as the principal alloying
element with or without other designated alloying elements such as iron,
aluminum, nickel and silicon. The wrought alloys comprise three main families
of brasses: copper-zinc alloys; copper-zinc-lead alloys (leaded brasses);
and copper-zinc-tin alloys (tin brasses). The cast alloys comprise four
main families of brasses: copper-tin-zinc alloys (red, semi-red and yellow
brasses); "manganese bronze" alloys (high strength yellow brasses); leaded
"manganese bronze" alloys (leaded high strength yellow brasses); copper-zinc-silicon
alloys (silicon brasses and bronzes); and cast copper-bismuth and copper-bismuth-selenium
alloys. Ingot for remelting for the manufacture of castings may vary slightly
from the ranges shown. |

Broadly speaking, bronzes are copper alloys in
which the major alloying element is not zinc or nickel. Originally "bronze"
described alloys with tin as the only or principal alloying element. Today,
the term is generally used not by itself but with a modifying adjective.
For wrought alloys, there are four main families of bronzes: copper-tin-phosphorus
alloys (phosphor bronzes); copper-tin- lead-phosphorus alloys (leaded phosphor
bronzes); copper-aluminum alloys (aluminum bronzes); and copper-silicon
alloys (silicon bronzes).
The cast alloys have four main families of bronzes: copper-tin alloys
(tin bronzes); copper-tin-lead alloys (leaded and high leaded tin bronzes);
copper-tin-nickel alloys (nickel-tin bronzes); and copper- aluminum alloys
(aluminum bronzes).
The family of alloys known as "manganese bronzes," in which zinc is
the major alloying element, is included in the brasses, above. |
| Copper-Nickel |
Wrought
700 - 734
Cast
960 - 969
|
These are alloys with nickel as the principal
alloying element, with or without other designated alloying elements. |
| Copper-Nickel-Zinc Alloys |
Wrought
735 - 799
Cast
970 - 979
|
Known commonly as "nickel silvers," these are
alloys which contain zinc and nickel as the principal and secondary alloying
elements, with or without other designated elements. |
| Leaded Copper |
Cast
980 - 989
|
These comprise a series of cast alloys of copper
with 20% or more lead, sometimes with a small amount of silver, but without
tin or zinc. |
| Special Alloys |
Cast
990 - 999
|
Alloys whose chemical compositions do not fall
into any of the above categories are combined in "special alloys." |
