• The Introduction explains the rationale of the EN series of standards

for coppers and copper alloys.

• Section 1 (page 5) shows, where possible, the equivalents to the old

British Standard materials.

• Section 2 (page 8) lists the ranges of compositions and properties of

coppers and copper alloys included in the EN standards that replaced the

old British Standards for these materials. For most materials it is easy to

obtain near-equivalents to those included in previous standards. Full

details of compositions and other requirements are included in the

standards, obtainable from The British Standards Institution.

• Section 3 (page 19) includes a selection of tables giving near-equivalents

for the brasses previously included in the British Standards in order to

simplify selection from the very wide range of materials now available.

• The CDA Technical Helpline offers free advice on the selection and use

of coppers and copper alloys.

Introduction

The EN StandardsThe EN series of standards for copper and copper alloys offers

a selection of materials to suit a very wide variety of end uses.

They represent a consensus agreement on those most

frequently ordered by consumers.

Commencing in the late 1980s, drafting of European

Standards for Copper and Copper Alloys became a major

activity for national standards’ organisations and their

industrial partners.

Because a large number of national preferences have needed

to be taken into account against the background of a pan-

European agreement to develop tight product standards, the

EN standards are more complex than the old BS standards.

Furthermore, the EN standards tend to cover narrower fields

than BS standards; hence there are more alloys in the EN

series than in the old BS standards.

This publication summarises the main compositions and the

range of properties. For full details refer to the standards

documents obtainable from: The British Standards

Institution, 398 Chiswick High Road, London W4 4AL.

Withdrawal of Old StandardsAs the new standards have been published they were in

conflict with the old British Standards. These were

withdrawn, as were those of other European countries,

leaving Europe with one harmonised series of standards

published in each country but applicable across all.

The majority of the new standards, published or due

during the period 1996-2003, caused withdrawal of

conflicting national standards such as BS 1400 for

castings, the BS 287x series for wrought materials and the

BS 143x series covering coppers for electrical purposes.

Materials popularly used from the old BS standards

continue to be available but the new designations should

be used.

Numbers and Titles of StandardsTable 1 shows EN standards’ titles, categorised by product

type, and the BS standards that have been replaced. During

the standardisation process, at the stage of draft for public

comment, an EN number is allocated. At this stage drafts are

identified with the prefix ‘pr’. After successful formal vote,

when the draft is approved for publication throughout

Europe, the EN implementation uses the same number.

Table 2 shows old BS standard numbers in numerical order

and their replacement EN standards.

Product FormsAs part of the standardisation process, uniform definitionshave now been adopted for all product forms. This willresult in some products having new terminology. As anexample, the term ‘wire’ now includes all material madein coil form.

Material DesignationsMaterial designations (individual copper and copper alloyidentifications) are in two forms, symbol and number.As with many other existing European national standards,symbols are based on the ISO compositional system (e.g.CuZn37 is 63/37 brass). ISO and EN symbols may beidentical but the detailed compositional limits are notalways identical and cannot be assumed to refer tounique materials.

Numbering SystemA new numbering system has therefore been developedto offer a more user- and computer-friendly alternative.The system is a 6-character, alpha-numeric series,beginning C for copper based material; the second letterindicates the product form as follows:-

B – Materials in ingot form for re-melting toproduce cast products

C – Materials in the form of cast products

F – Filler materials for brazing and welding

M – Master alloys

R – Refined unwrought copper

S – Materials in the form of scrap

W – Materials in the form of wrought products

X – Non-standardised materials

A three-digit number series in the 3rd, 4th and 5th placesis used to designate each material and can range from 001to 999. Numbers are allocated in preferred groups, eachseries being shown below. The sixth character, a letter,indicates the copper or alloy grouping as follows:-Number series Letters Materials

000-099 A or B Copper

100-199 C or D Copper alloys, low alloyed(less than 5% alloyingelements)

200-299 E or F Miscellaneous copper alloys (5% or more alloyingelements)

300-349 G Copper–aluminium alloys

350-399 H Copper–nickel alloys

400-449 J Copper–nickel–zinc alloys

450-499 K Copper–tin alloys

500-599 L or M Copper–zinc alloys, binary

600-699 N or P Copper–zinc–lead alloys

700-799 R or S Copper–zinc alloys, complex

Copper and Copper Alloys

Introduction to Standards

Symbol Designations The symbols used are based on the ISO designation

system (ISO 1191 Pt1).

The principal element, copper, is first.

Other alloying elements are included in decreasingorder of percentage content.

Where contents are similar, alphabetical order may beused.

The numbers after elements represent nominalcompositions.

No number is normally used if the nominalcomposition is less than 1%.

Material Condition (Temper) DesignationsMaterial condition (alternative term – temper)designations are defined in EN 1173. In most productstandards, materials are available in a choice of materialconditions. Depending on the product standard there maybe one or more mandatory properties associated with theparticular material condition. For designation purposesthe principal mandatory property for each materialcondition is identified by a letter, as follows:-

A – ElongationB – Spring bending limitD – As drawn, without specified mechanical

propertiesG – Grain sizeH – Hardness (Brinell or Vickers)M – As manufactured, without specified

mechanical propertiesR – Tensile strengthY – 0.2% proof strength

Products can only be ordered to one material conditionand not a combination. However, besides the designatingproperty, other properties may be mandatory; check thestandard document for full details.

Normally three digits, but in a few instances four digits,follow the material condition designating letter, whereappropriate, to indicate the value of the mandatoryproperty with the possibility of a final character, ‘S’, forthe stress relieved condition. Normally the value refers toa minimum for the property. Sometimes, as with grainsize, it refers to a nominal mid-range value.

Tables 6 to 12 show not only the existence of copperor copper alloys in particular standards but also thematerial conditions available as mandatory propertieswithin those standards.

CastingsFor castings, properties are dependent on the castingprocess used. This is designated according to the system:

GS sand casting

GM permanent mould casting

GZ centrifugal casting

GC continuous casting

GP pressure diecasting

ExamplesCW614N – R420 refers to wrought CuZn39Pb3

copper-zinc-lead alloy to besupplied to a minimum tensilestrength of 420 N/mm2

CC750S-GS refers to sand cast CuZn33Pb2copper-zinc duplex alloy

Ordering InformationEach product standard gives examples of the full orderinginformation required including quantity, product form,standard number, designation, condition, tolerances andpackaging.

Typical PropertiesIn Tables 6 to 12, typical properties are usually shown asranges. For materials available in both ‘soft’ condition, forexample as forging stock, and ‘very hard’, for example asspring wire, then the ranges are very wide. Tables 14 to 18show typical properties for ranges of brasses similar tothose previously included in British Standards in order togive a closer idea of the range of properties available ineach product form.

It is vital that designers and purchasers consult withsuppliers to clarify what property values andcombinations are available to be best fit for purpose in thedesired product form.

Declarations of ConformityWhere the full quality systems standardised in EN ISO9001 series of standards are not required, a declaration ofconformity may still be needed to confirm compliancewith order requirements:

In EN 1655 ‘Copper and Copper Alloys – Declarations ofConformity’, four levels of declaration of conformity areavailable:

Type A for suppliers who do not have a certified qualityassurance scheme.

Type B for suppliers who do not have a certified qualityassurance scheme but have access to an accreditedlaboratory.

Type C for suppliers who have a certified qualityassurance scheme but do not have access to anaccredited laboratory.

Type D for suppliers who have both a certified qualityassurance scheme and access to an assessed laboratory.

These declarations are more specific than those based onsystems used for steels included in EN 10204 ‘MetallicProducts – Types of Inspection Documents’.
