Aluminium could be another useful material to be implemented into the game. Here are some of the features this element could have:
*Melting point: 660.32C
*Is breakable like glass and BMTL due to pressure and breakable like WOOD due to kinetic energy; It will break into BREL.
**Likewise, BREL will melt at 660.32C (it doesn't melt in any way in the current version), due to the fact that it's reaction with BRMT to form THRM implies it's Aluminium. When BREL solidifies, it will either solidify into Aluminium (the default form) or the original electronic component.
*Will get "absorbed" by Mercury.
*Is a better heat conductor than other metals, but not as much as HEAC.
*Can conduct electricity.
Because you can turn BREL into EXOT at high temperatures, maybe have Aluminium turn into EXOT at high temperatures as well?
Making BREL melt would break a lot of saves. The fact that BREL doesn't melt not only makes it a good protector from LAVA, but it also allows BREL to turn into EXOT (BREL has to be at >9000C to turn into EXOT.) BREL is aluminum. So if you want SOLID aluminum, simply type a complex console command to make it. Or draw PIPE and replace the PIPE with BREL and the BRCK with conductive solid.
Just make a mod. But be warned, if it breaks saves, the game shoots out error messages and/or crashes or causes problems, you need to edit some of the code!
Plus, you could just make BALU, and it has the same melting point as ALUM and mixes with BRMT for THRM.
