Copper Alloys Designation Print

Copper Alloys Designation

Technologic relevance of copper and its alloys has always been recognized all over the world and each Country had developed its own classification method: for example a common brass for faucets used to be called C36000 by Americans, CZ124 by the English, 2.0375 by Germans, C3601 by the Japanese, Mässing 51 70-xx by the Swedish and LS63-3 by the Russian, while in Italy the name was OT57 and OT58.
Subsequently a way to designate alloys has been searched in order to obtain one only international identification based on numbers, symbols and codes.

 

 

Copper Alloys Designation

 ISO designation has been enforced and delved into by norm UNI EN 1412 (Copper and copper alloys – European system of numeric designation) and it introduces a line of 6 characters in numbers (0) and capital letters (X) organized in the following order: XX000X.
Copper alloys’ designation always starts with letter C.
The second letter identifies material: for example W indicates semifinished products and C indicates castings.
The three numbers stated are between 000 and 999; if material is unified the number is between 000 and 799, if it is not unified the number is between 800 and 999.

 

Copper Alloys Designation

 

The last letter indicates the type of alloy: A or B stand for copper; L or M stand for copper-zinc alloys; K for copper-tin alloys and so on.
As an example a common 99,90% copper plate (normally used in building industry) is designed by code CW024A.
A further international method is ISO 1190-1, also reported in CR 13388, the document prepared by CEN which gathers the copper alloy compositions.


 

 Copper Alloys Designation

 The alloy is designed by a variable length code which reports its elements as chemical symbol and their assigned percentage in a whole number. At the beginning of each abbreviation “Cu” symbol is always stated: it stands for the basic metal.
For example common faucets brass containing an average of 39% of zinc and 3% of lead is designed with CuZn39Pb3.
In case copper is pure (around 99,90% minimum) indication of composition is for example Cu-DHP for Deoxidized High residual Phosphor, Cu-ETP for Electrolitic Tough Pitch, Cu-OF for Oxygen Free, etc.
