EN 1982:2008 (E)
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 standard does not include copper refinery shapes which are intended for working into wrought products
and are the subject of EN 1976. Neither 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, which is based upon the recommended practice for the ordering and supply of castings given in
EN 1559-1. Its purpose is to assist the purchaser in providing full information to the supplier to ensure that he
supplies castings to the purchaser's intended requirements. It is recommended that full consultation takes
place between the purchaser and the supplier at the stages of enquiry and ordering.
Sampling and testing rates, where applicable, are specified in Clause 7. For certain applications, more
rigorous inspection procedures may be required. Annex B gives a range of supplementary inspection
procedures which may be invoked, at the option of the purchaser [see 5 p)].

3.2
batch
any of the following:
a) number of ingots taken from a single cast; or
b) number of castings of the same design produced from a single cast; or
c) portion of the output of a continuous caster during a cast.
4 Designations
4.1 Material
4.1.1 General
The material is designated either by symbol or number (see Tables 1 to 40).
4.1.2 Symbol
The material symbol designation is based on the designation system given in ISO 1190-1. 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 CuSn5Zn5Pb5-C). These suffixes also serve to avoid
confusion with wrought products of a similar alloy.
NOTE Although material symbol designations used in this standard might be the same as those in other standards
using the designation system given in ISO 1190-1, 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 (for example
CuSn5Zn5Pb5-C is CC491K).
4.2 Casting process
The designations used to indicate the casting processes referred to in this standard are based on those given
in ISO 1190-1, as follows:
GS sand casting;
GM permanent mould casting;
GZ centrifugal casting;
GC continuous casting;
GP pressure die casting.
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 to this standard shall consist of:

6 Requirements
6.1 Composition
The composition of ingots and castings shall conform to the requirements for the appropriate material given in
Tables 1 to 40. The analysis shall be carried out in accordance with 8.1. In the case of ingot casts of more
than 2 t, both samples selected in accordance with 7.2.2 b) shall conform to the composition requirements.
NOTE 1 In Tables 3 to 40, elements with known harmful effects are shown separately, below the line, from alloying
elements. Maximum limits for these harmful elements are specified.
NOTE 2 Small amounts of residual elements other than those listed in the composition Tables 3 to 40, for example As,
Bi, Cd, Co, Cr, Mg, Ti, may be present in amounts which generally have no deleterious effects. If requested at the time of
placing the order, the analytical determination of any of these elements, or of any other residual element not included in
the composition tables, together with limiting values, should be agreed between the purchaser and the supplier. Usually
such elements (excluding oxygen) will not exceed 0,05 % individually in ingots or 0,06 % in castings, and the total of such
elements will not usually exceed 0,20 % in ingots or 0,25 % in castings.
NOTE 3 In all tables of composition the "Remainder" is the balance between the sum of the elements determined and
100 %. It is not determined by analysis.
6.2 Mechanical properties
The mechanical properties of castings shall conform to all the requirements relevant to the material and
casting process given in Tables 1 to 40. The test(s) shall be carried out in accordance with 8.2.
NOTE 1 No mechanical properties are specified for ingots.
NOTE 2 The mechanical properties specified in this standard relate to separately cast test bars unless otherwise stated.
Separately cast test bars have a valuable function as a check on the quality of the material and also on the foundry
technology. It is emphasized that 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.
NOTE 3 All the mechanical properties given for castings in Tables 1 to 40 are mandatory requirements (but see note 4).
However, only those mechanical properties printed in bold typeface are normally determined on a routine basis.
Determination of the other properties should be specifically requested, if required [see 5 o)].
NOTE 4 Because of the dependence of the properties of pressure die castings on the injection parameters, the
mechanical properties given in Tables 4, 5, 7, 8, 10 and 12 are given for information only.
11
---------------------- Page: 12 ----------------------
EN 1982:2008 (E)
6.3 Electrical properties
The electrical conductivity of Cu-C (CC040A) castings shall conform to the requirements given in Table 1. The
electrical conductivity of CuCr1-C (CC140C) castings shall conform to the requirements given in Table 2. 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 5 k)].
Ingots in certain alloys shall have maximum average grain diameters, as follows:
0,150 mm for material CuZn35Pb2Al-B (CB752S) (see Table 5) and CuZn39Pb1Al-B (CB754S) (see
Table 7), when specifically ordered in the grain refined condition [see 5 i)];
0,100 mm for material CuZn39Pb1AlB-B (CB755S) (see Table 8);
0,300 mm for material CuZn37Pb2Ni1AlFe-B (CB753S) (see Table 6).
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 in CuZn33Pb2Si-C (CC751S) and
CuZn35Pb2Al-C (CC752S) (see Tables 4 and 5), produced by permanent mould or pressure die 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 Freedom from defects
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 agreed between the purchaser and the supplier at the
time of ordering [see 5 p)]. Gates and feeders shall be removed and residues of moulds shall be removed
from accessible surfaces.

consequence a different sampling regime has been agreed, the minimum sampling and testing rates 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, mechanical properties test or dezincification resistance test shall be
as given in 8.7.
7.2 Analysis
7.2.1 General
Samples shall be taken from the melt they represent and poured into a clean chill mould, which is designed to
give analysis samples of a shape and size appropriate to the analytical technique 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 rate of one per cast [see definition of cast in 3.1 d)].
7.2.3.2 Continuous casting
Samples shall be taken during the run of a cast [see 3.1 e)] at a rate 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 rate of sampling shall be left to the discretion of the founder.
For other furnace charge constituents, samples shall be taken from the melt to represent each cast.
