European foreword
This document (EN 12163:2024) has been prepared by Technical Committee CEN/TC 133 “Copper and
copper alloys”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2025, and conflicting national standards shall be
withdrawn at the latest by April 2025.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12163:2016.
In comparison with EN 12163:2016, the following significant technical changes were made:
a) Introduction of 6.7 Internal inclusion;
b) Modified the definition of diameter or width across-flats at 6.5.1;
c) Added a new Figure for straightness at 6.5.3 and modified values in Table 18
d) CuSi4Zn4MnP (CW245E) and CuSi4Zn9MnP (CW246E) added in the new Table 2 and new Table 10
e) CuSn5 (CW451K) added in Table 6 and Table 14;
f) Introduction in the chemical composition Tables of a footnote to explain the meaning of elements for
which no upper and lower limits are specified;
g) Annex ZA added.
This document is one of a series of European Standards for the copper and copper alloy products rod,
wire, profile and forgings. Other products are specified as follows:
— EN 12164, Copper and copper alloys — Rod for free machining purposes;
— EN 12165, Copper and copper alloys — Wrought and unwrought forging stock;
— EN 12166, Copper and copper alloys — Wire for general purposes;
— EN 12167, Copper and copper alloys — Profiles and bars for general purposes;
— EN 12168, Copper and copper alloys — Hollow rod for free machining purposes;
— EN 13601, Copper and copper alloys — Copper rod, bar and wire for general electrical purposes;
— EN 13602, Copper and copper alloys — Drawn, round copper wire for the manufacture of electrical
conductors;
— EN 13605, Copper and copper alloys — Copper profiles and profiled wire for electrical purposes.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
