- Heating element wire
- Max continuous operating temperature - 1400C 
- It should be able to melt ductile and grey iron with it. 
- Easy pickins - high T chamber sufficient to melt ZA Alloys is possible - 400C to melt with resulting 45ksi strength - as strong as steel.
- Note that high temperature 3D printer nozzles can do 400C. 
- Copper heater blocks go up to 500C.
