RELEVANT PROPERTIES FOR USE IN SPACE COMMUNITY
Stress Corrosion StatusHigh Resistance to SCC: Table 1
Remark: The alloy is not recommended for continuous service at temperatures above 66°C because of accelerated aging at elevated temperatures which may increase the susceptibility of the alloy to stress corrosion cracking
EMF vs SCE-0.77 V
Bimetallic CorrosionCan be used in a non-controlled environment: Al alloys, Cd
Can be used in a clean room environment: Mg, Sn-Pb alloys (all), Sn, Pb, Zn, Be
Needs specific measures: All others
