I am trying to determine what the best material is for a high temperature conductor. It is for distributing power inside a furnace. I need to run at around 1000 celsius (the furnace is hotter but this is how hot the conductors might get). The lower the resistance, the better. Platinum is not an option for me.
It seems most refractory metals (all besides platinum?) are problematic in the open air with oxidization at these temperatures - even tungsten will rapidly oxidize at 1000C and above. I can coat the wire to protect it, but have not been able to determine what could be reliably used.
