	RELEVANT PROPERTIES FOR USE IN SPACE COMMUNITY

Stress Corrosion Status

High 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 Corrosion

Can 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 Remark: ECSS-Q-ST-70C Rev.1 table 5.1 Data Quality: Design Data

	SPECIAL RECOMMENDATIONS

Lessons Learned

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
