The 40 Copper Alloys regularly available in the USA

Variations of the alloys

Remember - many of the alloys below occur in several variations (7 variations of copper, for example). This is often because of very minor variations in the metallurgy of the alloy that enhance a particular characteristic of the alloy, such as ductility or machinability. These changes in metallurgy give rise to variations different enough to warrant assigning the alloys their own UNS number, but not different enough to assign them a different name.

Description N/A This alloy standard is not simply a piece of metal - it is an identified piece of metal - a documentation of color, name, and available forms. It is a definitive document that makes your metal specification strong.

With this document you can definitively color match your metal designs with the rest of your project.

With this document you can reliably and authoritatively specify the forms in which you now know the metal is regularly available in the USA.

If you encounter resistance to using these metals because of a contractor's concern about its availability, workability, function, or just plain existence, this document will enable you to specify with the authority to ensure that your metal designs actually get built with the materials you want.

Additional Information N/A These variations are grouped together below. They are the same color, and can be specified interchangeably for ornamental work. Simply let your fabricator know which form of the alloy you would like, and indicate that any of the alloys in the group will be satisfactory. The supplier will then provide the appropriate forms of that metal in any of the interchangeable alloys of that metal.
Note N/A These are all "Copper". Specify the form you want, and accept from this group the alloy in which it is available. N/A These are all "Beryllium Copper". Specify the form you want, and accept from this group the alloy in which it is available. N/A N/A These are all "Commercial Bronze". Specify the form you want, and accept from this group the alloy in which it is available. N/A These are both "Red Brass".
