Introduction
This European Standard for copper alloy ingots, and copper and copper alloy castings is based on
previous national standards and harmonizes the compositions and mechanical properties required.
This European Standard does not include copper refinery shapes which are intended for working into
wrought products and are the subject of EN 1976. Nor does it include master alloys intended for the
manufacture of copper alloys which are the subject of EN 1981.
The essential information relevant to correct ordering, given in Clause 5 of the standard, is
supplemented by Annex A. Its purpose is to assist in providing full information to ensure that the
castings are in accordance to the specified requirements. It is recommended that full consultation takes
place at the stages of enquiry and ordering.
Sampling and testing frequency, where applicable, are specified in Clause 7. For certain applications,
more rigorous inspection procedures may be required. Annex B gives supplementary inspection
procedures which may be invoked, see Clause 5 o).
Some copper and copper alloys can be used in castings for pressure equipment. Ingots are not suitable
for pressure equipment.
The permitted material grades of copper and copper alloys for pressure applications and the conditions
for their use are given in specific product or application standards.
For the design of pressure equipment, specific design rules apply.
Annex ZA gives information relating to the conformance of permitted material grades of copper and
copper alloys used in castings to the New Approach Pressure Equipment Directive 2014/68/EU.
NOTE Brittle fracture prevention: copper, having a face-centred cubic crystal structure, does not suffer a
transition from ductile to brittle failure like some other materials.
The European Committee for Standardization (CEN) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent concerning the alloy CuZn21Si3P-B
(CB768S) and CuZn21Si3P-C (CC768S) given in Table H.2 as well as concerning the alloy CuSn12S-B
(CB472K) and CuSn12S-C (CC472K) given in Table J.6 as well as concerning the alloy CuSi4Zn4MnP-B
(CB245E) and CuSi4Zn4MnP-C (CC245E) given in Table Q.1 as well as concerning the alloy
CuSi4Zn9MnP-B (CB246E) and CuSi4Zn9MnP-C (CC246E) given in Table Q.2 as well as concerning the
alloy CuSi3Zn12FeMnP-B (CB247E) and CuSi3Zn12FeMnP-C (CC247E) given in Table Q.3 as well as
concerning the alloy CuSn4Zn2PS-B (CB470K) and CuSn4Zn2PS-C (CC470K) given in Table L.1 as well
as concerning the alloy CuSn7Zn3Ni2PS-B (CB471K) and CuSn7Zn3Ni2PS-C (CC471K) given in
Table L.2.

4 Designations
4.1 Material
4.1.1 General
The material is designated either by symbol or number (see Annex C to Annex Q, Tables C.1, D.1, E.1, F.1
to F.4, G.1 to G.9, H.1 to H.2, I.1 to I.4, J.1 to J.8, K.1 to K.5, L.1 to L.2, M.1 to M.4, N.1 to N.5, O.1, P.1 to P.4,
Q.1 to Q.3).
4.1.2 Symbol
The material symbol designation is based on the designation system given in ISO 1190-1:1982. A suffix -
B is added to the designation to identify material in the form of ingots and a suffix -C is added to the
designation to identify material in the form of castings (for example CuSn5Zn5Pb2-C). These suffixes
also serve to avoid confusion with wrought products of a similar alloy.
NOTE Although material symbol designations used in this document might be the same as those in other
standards using the designation system given in ISO 1190-1:1982, the detailed composition requirements are not
necessarily the same.
4.1.3 Number
The material number designation is in accordance with the system given in EN 1412:2016.
4.2 Casting process
The designations used to indicate the casting processes referred to in this document are based on those
given in ISO 1190-1:1982, as follows:
GS sand casting;
GM permanent mould casting;
GZ centrifugal casting;
GC continuous casting;
GP pressure die casting.
NOTE Pressure die castings are produced by the injection and solidification of molten metal under
substantial pressure, typically above 70 bars, into a metal die. The terms “die casting”, “pressure die casting” or
“high pressure die casting” are often used for this concept.
4.3 Product
The product designation provides a standardized pattern of designation from which a rapid and
unequivocal description of a product is conveyed in communication. It provides mutual comprehension
at the international level with regard to products which meet the requirements of the relevant
European Standard.
The product designation is no substitute for the full content of the standard.
The product designation for products specified in this document shall consist of:
— denomination (ingot or casting);
— number of this European Standard (EN 1982);
— material designation, either symbol or number (see Annex C to Annex Q);

properties shall be specified. Ingots are not suitable for pressure equipment.
6.2.2 Castings
The mechanical properties specified in Annex C to Annex Q are related to castings and are not valid for
ingots. The mechanical properties of castings shall conform to all the requirements relevant to the
material and casting processes given in Annex C to Annex Q. The test(s) shall be carried out in
accordance with 8.2.
The mechanical properties specified in this document relate to separately cast test bars unless
otherwise stated. Mechanical properties are wall thickness dependant. If applicable, it shall be specified
on the minimum values to be obtained and the type and size of the cast sample.
The mechanical properties obtained when testing a casting may differ from those obtained from a
separately cast test bar(s) because of possible differences in structure between the test bars and the
castings, arising mainly from variations in section thickness.
6.3 Electrical properties
The electrical conductivity of Cu-C (CC040A) castings shall conform to the requirements given in
Table C.1. The electrical conductivity of CuCr1-C (CC140C) castings shall conform to the requirements
given in Table D.1. The test shall be carried out in accordance with 8.3.
NOTE 0,58 MS/m is equivalent to 1 % IACS.
6.4 Microstructure and grain size
For marine and other applications requiring high resistance to corrosion, the microstructure of
CuZn35Mn2Al1Fe1-C (CC765S) castings shall reveal a minimum of 15 % alpha-phase when tested and
examined as described in 8.4.1 [see Clause 5 k)].
Ingots in certain alloys shall have maximum average grain size, e.g.:
— 0,150 mm for material CuZn35Pb2Al-B (CB752S) (see Table G.3), CuZn36Pb-B (CB770S) (see
Table G.4) and CuZn39Pb1Al-B (CB754S) (see Table G.6), when specifically ordered in the grain
refined condition [see Clause 5 i)];
— 0,100 mm for material CuZn39Pb1AlB-B (CB755S) (see Table G.7) and CuZn39Pb1Al-B (CB757S)
(see Table G.8);
— 0,300 mm for material CuZn37Pb2Ni1AlFe-B (CB753S) (see Table G.5).
The tests shall be carried out in accordance with 8.4.2.
6.5 Dezincification resistance
The depth of dezincification after the test, in any section of a casting shall be:
— for Grade A: maximum 200 μm;
— for Grade B: mean not to exceed 200 μm and maximum 400 μm.
The test shall be carried out in accordance with 8.5.
6.6 Outer and inner conditions
6.6.1 Ingots
Ingots shall be free from dirt, dross, slag and residual moisture.
6.6.2 Castings
The castings shall be supplied fettled unless otherwise specified at the time of ordering [see
Clause 5 o)]. Gates and feeders shall be removed and residues of moulds shall be removed from
accessible surfaces.
7 Sampling and testing frequency
7.1 General
Except where a manufacturer operates a certified quality system, and as a consequence a different
sampling regime has been agreed, the minimum sampling and testing frequency for verifying
conformity to the requirements of this standard for composition, mechanical properties, microstructure
and dezincification resistance shall be as given in 7.2 to 7.5. The procedures for retesting in the event of
a test piece failing the analysis of the chemical composition, mechanical properties tests or
dezincification resistance test shall be as given in 8.7.
7.2 Analysis of the chemical composition
7.2.1 General
Samples shall be taken from the melt they represent and poured into a clean chill mould having a shape
and size appropriate to obtain a sample compatible with the analytical techniques to be employed.
7.2.2 Ingots
Samples shall be taken from the melt to represent each cast, as follows:
a) for casts of 2 t or less, one sample shall be taken;
b) for casts of more than 2 t, two samples shall be taken, one at the beginning of the cast and one at the
end of the cast.
7.2.3 Castings
7.2.3.1 Casting from a holding furnace
Samples shall be taken from the holding furnace at a frequency of one per cast [see definition of cast in
3.3 d)].
7.2.3.2 Continuous casting
Samples shall be taken during the run of a cast [see 3.3 e)] at a frequency corresponding to the pouring
of each new melt.
7.2.3.3 Non-continuous casting
When the furnace charge consists wholly of:
a) ingots for which an analysis is already available; and/or
b) properly segregated and identified foundry returns,
then the frequency of sampling shall be specified.
For other furnace charge constituents, samples shall be taken from the melt to represent each cast.
7.3 Mechanical tests
7.3.1 Mechanical testing of ingots
No minimum inspection requirements for the testing of ingots for mechanical properties are specified.
It may be specified tensile testing of ingots as an optional requirement (see B.3.1).
7.3.2 Mechanical testing of continuous castings
When mechanical properties are specified, the minimum sampling and testing frequency shall be one
sample for each 5 t of product of identical dimensions and composition, except that for hardness testing
of castings in CuCr1-C (CC140C), where the minimum frequency shall be one test per cast, or per heat
treatment batch, whichever is the smaller mass.
7.3.3 Mechanical testing of non-continuous castings
The minimum sampling and testing frequency for non-continuous castings shall be:
a) for castings in alloys CuZn35Mn2Al1Fe1-C (CC765S), CuZn34Mn3Al2Fe1-C (CC764S),
CuZn25Al5Mn4Fe3-C (CC762S), CuAl10Fe2-C (CC331G), CuAl10Ni3Fe2-C (CC332G),
CuAl10Fe5Ni5-C (CC333G), CuAl11Fe6Ni6-C (CC334G), CuAl9-C (CC330G), CuMn11Al8Fe3Ni3-C
(CC212E), CuNi30Cr2FeMnSi-C (CC382H) and CuNi30Fe1Mn1NbSi-C (CC383H) (see Table I.1,
Table I.3, Table I.4, Table N.1 to Table N.5, Table O.1, Table P.3 and Table P.4), at a frequency
corresponding to one test per cast [as defined in 3.3 a), 3.3 b) or 3.3 c)], or one test per 1 t of fettled
castings, whichever is the minimum frequency of testing;
b) for castings in all other alloys for which routinely determined mechanical properties are required,
at a frequency corresponding to one test per 5 t of fettled castings;
c) for castings in alloy CuCr1-C (CC140C), the minimum sampling frequency for hardness testing shall
be one test per cast, or per heat treatment batch, whichever is the smaller mass.
