EN 4632-005:2009 (E) 4 1 Scope This European Standard defines degrees of weldability and brazeability for materials or families of materials used in the aerospace industry. It comprises a series of sheets, by materials or by material family, which:  indicate the main titles, the chemical composition and the main characteristics;  contain recommendations for welding and brazing;  indicate a degree of weldability or brazeability for a given process under defined conditions;  indicate a value of the mechanical strength coefficient of the welded joint for each welding process, when it could be extracted from bibliographic references referring to it. The joint coefficient is expressed as a ratio of the tensile strength of the welded joint to the tensile strength of the base alloy (to be in accordance with EN 4632-002). It is applicable without restriction for the manufacturing of new parts or for repair. 2 Normative references The following referenced documents are indispensable for the application of this document.

The degree of weldability or brazeability (see EN 4632-001) to be used is the value indicated by the material sheet considered for the process chosen. In the operating cycle, preferably select thermal states that give the lowest degree. If two degrees are indicated, the responsible person shall select the degree that is most appropriate for the definition of the assembly. 5 Updating this standard See EN 4632-001. 6 List of heat resisting Ni or Co base alloys Table 1 Sheet Material 7.1 7.2 7.3 7.4 7.5 7.6 7.7 7.8 7.9 7.10 7.11 7.12 7.13 7.14 7.15 7.16 7.17 7.18 NiCr15Fe NiCr16Co10Mo8Al4Ti4 NiCr19Fe19Nb5Mo3 NiCr19Fe19Nb5Mo3 NiCr19Co11Mo10Ti3 NiCr20Co13Mo4Ti3Al NiCr20Nb NiCr20Ti NiCr22Mo9Nb NiCr22Mo9Nb NiCr21Fe18Mo9 NiCr21Fe18Mo9 NiCr22Co13Mo9Al1 NiCo20Cr20Mo5Ti2Al NiCo20Cr20Mo5Ti2Al CoCr20W15Ni CoCr26Ni11W CoCr22Ni22W15
