COPR - Copper
-
Conducts SPRK but turns it into a similar colour to the copper without a glow. (so you can see what you are doing when making or using electronics, while still having the graphics of other display modes.)
Immune to EMP and prevents anything is within a 5x5 square around it from being damaged by EMPs.
Creates negative pressure when sparked. (Currently the only elements that create negative pressure are indestructable or break when they make it. Also means you can depressurise an area slowly so you don't break anything.)
It conducts electricity faster if there are more particles of COPR touching it. (half speed if there are none, normal speed if there are 1 or 2, slightly faster if there are 3-5, even faster if there are 6-8) This means thicker wires will work better, and adds a bit of realism.
Conducts when there are layers over the top of it. (Not sure if this is possible, but could make a useful alternative way to hide electronics.)
Conducts heat to other COPR particles almost instantly, but will transfer heat to anything else at the same speed as METL. (Used to transfer heat evenly without cooling down too quickly)
Can't be rusted by WATR, only OXYG and SLTW. (Makes it heat water better, I wasn't really thinking of a use for this one)
Makes a 1 frame red beam that EMPs any pixels it touches when used with aray. (allows you to have machines that turn electronics into BREL without destroying the whole screen, adds a cool new weapon type, and could have some electronic uses.)
Doesn't detonate GBMB or DMG, and can not be created by grey EXOT, this means you can use these in machines without needing to use diamond or walls. Also makes is useful for making armour.
Other than that it has the same properties as METL (Yes I do know METL is meant to be copper)

"Conducts when there are layers over the top of it. (Not sure if this is possible [...])" - without a massive rewrite to use linked lists for pmap, no it's not.
Variable heat conduction speed to different elements is difficult at the moment. Heat conduction speed is currently controlled by limiting the proportion of frames for which each particle conducts to its neighbours, based on the type of that particle. If it does conduct on a particular frame, it conducts to all neighbours by an equal amount. This is why, for example, a 1 pixel layer of QRTZ (which conducts heat very slowly) around some DMND, actually swaps heat with the DMND very fast. The DMND conducts heat to the QRTZ every frame - it's not influenced by the fact that the DMND is conducting to QRTZ.
What exactly is the reasoning behind this property? Is there a particular real world behaviour it's trying to replicate?
SPRK in other electronic materials would still be as bright, so unless you build electronics almost entirely out of COPR you might still need to turn off SPRK.
Negative pressure can be produced in response to SPRK by pulsing PUMP on and off, which also allows control of the amount of pressure produced.
Perhaps you could expand on what the other properties would be useful for, and why they make sense for copper. For some of them, I'm just thinking "why? what's the point?". In particular: not detonating GBMB or DMG, not creatable by grey EXOT, can't be rusted by WATR.
