Explanatory comments on the alloy tables
In the EN 1982:2008 Standard, each copper casting alloy is assigned with a
number and a symbol. The following conventions apply:
• Representation in number form:
Ingot: CB …
Casting material: CC …
• Representation in symbol form:
Ingot: …-B
Casting material: …-C
The following conventions apply for the old abbreviated designations also listed:
Ingot: GB-…
General casting material: G-…
Casting materials for particular casting processes (partially listed):
Sand casting: GS-…
Permanent mould casting: GM-…
Centrifugal casting: GZ-…
Continuous casting: GC-…
Pressure die casting: GP-…

Details of the numbering system
The material number must be made up of alphabetic (Latin capital letters) and
numeric (Arabic numerals) characters.
The numbering system may only issue one number for each material.
A number that has been assigned to a particular material may not be assigned to
any other material, even in the event that the first material has been withdrawn.
Introduction
The European EN 1982:2008 Standard has been prepared by
Technical Committee CEN/TC 133 'Copper and Copper Alloys',
the Secretariat of which is held by DIN and was accepted by
the CEN (Comité de Normalisation) on the 21st of March 2008.
It exists in three official versions (English, French, German).
With respect to the old version from 1998, various modifications
and amendments have been made, in particular incorporation
of a new alloy in section 4 (CB499K + CC499K).
This new European Standard for copper alloy ingots and
copper and copper alloy castings is based upon previous
national standards and harmonises the chemical compositions
and mechanical properties required. Furthermore, it provides
information with regard to the individual areas of application.
For reasons of simplification, the old abbreviated designations
as well as the old standard designations have been placed
opposite the individual alloys.
Structure of the material numbers
The material number must be made up of 6 characters. The characters have the
following positions:
1
2
3
4
5
6
This standard does not include copper refinery shapes which
are intended for working into wrought products. These are the
subject of EN 1976. Master alloys are also not included in this
standard. They are the subject of EN 1981.
Position 1:
In accordance with ISO/TR 7003, the character in the first position must be the
letter ‘C’ in order to describe the copper material.
Position 2:
The character in the second position must be one of the following letters:
B
Materials in block form (e.g. ingots) for re-melting during the manufacture
of castings
C
Materials in casting form
F
Welding fillers and hard solders
M
Master alloys
R
Refined unwrought copper
S
Materials in scrap form
W
Wrought materials
X
Non-standardised materials
Positions 3 - 5:
The characters in the third, fourth and fifth positions must form a figure
between 000 and 799 with standardised copper materials and must form a
figure between 800 and 999 with non-standardised copper materials.
These characters have no further particular meaning.
Position 6:
The character in the sixth position must be a letter, with which one of the
following material groups is described:
A, B Copper
C, D Low alloy copper alloys (alloying elements amount to less than 5 %)
E, F Special copper alloys (alloying elements amount to a minimum of 5 %)
G
Copper-aluminium alloys
H
Copper-nickel alloys
J
Copper-nickel-zinc alloys
K
Copper-tin alloys
L, M Copper-zinc alloys, dual-material alloy
N, P Copper-zinc-lead alloys
R, S Copper-zinc alloys, multi-material alloys
Note:
The bold, non-italic values illustrated in the ‘alloy composition in percent
(mass fractions)’ tables describe the alloy constituents; the non-bold, italic values
illustrated describe the permitted additions or impurities.
The European EN 1982:2008 Standard specifies the composition,
mechanical properties and other relevant characteristics of the
materials. The sampling procedures and test methods for the
verification of conformity to the requirements of this standard
are also specified.
The standard is applicable for:
a) copper alloy ingots intended to be remelted for the
production of castings; and
b) copper and copper alloy castings which are intended for use
without subsequent working other than machining. The
castings may be manufactured by the sand, permanent
mould, centrifugal, continuous or pressure die casting process.
Please consult the complete version for further details with
regard to this standard, published by Beuth Verlag GmbH,
D-10722 Berlin, Germany.
The details in this list are provided to the best of our knowledge.
However, the application of these details in practice is subject to
many influencing factors beyond our control, meaning that we
cannot assume any liability for this.

a) For sand castings for non-bearing applications
the phosphorus may be restricted to 0.15 max.
(Note: See ordering information of
EN 1982:2008 for different compositions for
special applications).
Alloy from Great Britain. Has a
tendency to react to the moulding
material due to the high phosphorus content. Phosphorus increases the hardness and strength
at the expense of the elongation.
Same fields of application as CC482K and CC483K.

information of EN 1982:2008).
Construction material. Primarily used in Great
Britain, with low permeability.
Construction parts for the shipping industry, also
suitable for use as propeller material.
Excellent corrosion resistance against all types of
water such as drinking water, river water, brackish
water, mine water, sea-water as well as acidic and
ammoniacal condensates.
Used in ship construction, paper machine
construction, in the foodstuff and drinks industry,
in power plants and in the chemical industry for
fittings, mountings, pumps, measurement devices,
agitators, filling units, etc.

Master alloy for the alloying of Ni into Cu alloys.
Use as with CC380H and CC383H. Can be welded
easily, excellent corrosion resistance.
Note: Ingot properties for
producing castings conforming
to CuNi30Cr2FeMnSi-C
(CC382H) are not specified in
this standard. The composition
limits for ingots are at the
discretion of the purchaser and
shall be stated on the enquiry
and order (see ordering
information of EN 1982:2008).
This product contains 1.5 - 2.0 % Cr. Excellent
corrosion resistance against all types of water such
as drinking water, river water, brackish water, mine
water, sea-water as well as acidic and ammoniacal
condensates.

water, mine water, sea-water as well as acidic and
ammoniacal condensates.
Used in ship construction, paper machine
construction, in the foodstuff and drinks industry,
in power plants and in the chemical industry for
fittings, mountings, pumps, measurement devices,
agitators, filling units, etc.
No sensitivity against stress corrosion cracking.
Good erosion and cavitation resistance.
Can be welded easily – when the Si and Nb
contents are matched correctly – can also be
welded with c-steels.
Both alloys can be soft and hard soldered –
however, welding is preferable.
Can be machined well.
