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to a particular material may not be assigned to any other material, even in the event that the first material has been withdrawn.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.

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.
