ESA/ECSS used to provides a preferred list of materials for use in their space programs: on their ESMAT website as well as in the ECSS-Q-70-71 standard. This list of space-approved materials has been superseded by ECSS-Q-ST-70-71C (15 October 2014), however this new issue does nto provide a list of approved materials that are commonly used in European space programs. The following list is therefore an enhanced list based on the old ECSS-Q-70-71 standard, enhanced with more materials that are space-qualified but absent from the old list.
