- ANumber of transition elements in the alloy: 4; relative density compared to sodium: higher
- BNumber of transition elements in the alloy: 4; relative density compared to sodium: lower
- CNumber of transition elements in the alloy: 5; relative density compared to sodium: higher
- DNumber of transition elements in the alloy: 5; relative density compared to sodium: lower
