Dürrer,
The table in the Wikipedia article  
   https://en.wikipedia.org/wiki/Galvanic_corrosion#Anodic_index   
has more entries, is more descriptive, and doesn't totally agree with
Table 7-1 on page 156 of Gershon J. Wheeler's book, The Design of
Electronic Equipment: A Manual for Production and Manufacturing:

Table 7-1 Galvanic Series

Metal                         Anodic Index (0.01 volt)
