It would be nice if you could "smelt" your own metal alloys and save them in a custom alloy list. No matter what metals they are and no matter how many you combine, they would share their properties. Here are some use examples:
Titanium - Tungsten Alloy: Helps titanium withstand more heat and, in turn, makes tungsten much less brittle.
Iron - Titanium Alloy: The medium of strength between the two. Resists corrosion. Still allows the electrolysis of water.
Gold - P-Type Silicon Alloy: Transfers currents like P-type silicon, but twice as fast.
Gold - N-Type Silicon Alloy: Transfers currents like N-type silicon, but twice as fast.
etc.
How would the GOLD/PTCT alloy react with the GOLD/NTCT alloy, taking that NTCT doesn't give charge to PTCT?
COuld alloys not have conductivities that are the average of the involved element's conductivities? Surely a mix of gold and ptct will have a conductivity between that of gold's and ptct's.
Otherwise a great idea +1
Basically what they would have to do is make all new elements for each alloy that is wanted and make it to where you combine elements together in order to make the alloy. That would make a lot of useless alloys which would make useless/boring elements in TPT. There is no reason for them to be implemented.
