• Heating element wire
• Max continuous operating temperature - 1400C [1]
• It should be able to melt ductile and grey iron with it. [2]
• 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. [3]
• Copper heater blocks go up to 500C. [4]
