What if somebody would add an Alloying Machine to Satisfactory? It would have two inputs and one output, and it would melt two ingots of different metal to two alloyed ingots. New Metals could be implemented too.
There could be materials like:
-Tin Ingot (made of Tin Ore)
-Silver Ingot (made of Silver Ore)
-Lead Ingot (made of Lead Ore)
-Bronze Ingot (Tin Ingot + Copper Ingot)
for better tools and weapons
-Electrium Ingot (Silver Ingot + Caterium Ingot)
for better cables
-Solder (Lead Ingot + Tin Ingot)
for Solder Wire, for Soldering
