uxcell Heating Element Coil Wire AC220V 3000W / AC110V 750W Kiln Furnace Heater Wire 7.2mmx800mm 3PCS

Works to at least 1200C furnace air temperature. Gets pretty brittle once used (this is normal). Just make sure you don't ever need to move/adjust it once it is in use.You need to use an SCR controller to start gradually reducing coil power as you get above about 800C, to prevent melting. This is normal too. It's in the published reference guides about FeCrAl alloy heating elements. Don't just plug it straight into the mains socket if you want it to survive to >1000C furnace temperatures.Had a couple initial issues with end contacts melting, but I think this was probably user error in making the contacts. Arcing once an oxide layer formed. I fixed this by stretching and soldering the ends of the element to some thick gauge copper wire. Keep the ends of the element out of your furnace hot zone to avoiding melting the contacts, obviously....I cannot currently prove that this is Kanthal-A1. It might be Kanthal-D. Sooner or later I will run to 1400C, though-- and then I will know for certain.Anyway these are my current favorite element type for quick and simple high temperature heating projects. It really saves a lot of time not having to wind your own coil.

I managed to cut my lengths with +/_ .5 ohms

works well

The media could not be loaded. I used 120V and a PID controller.First Test:My Multimeter literally decided to break right when I decide to do this, so I didn't get to decide what resistance to use.I decided to cut off 1/8 of a coil and go crazy because I liked how bright it glowed.It tripped my 20A breaker and burned out before I got to 700°F. Bummer.Second Try:I still didn't have a multimeter. It's later in the day and I decide I'm going to try again. This time I cut approximately 3/16 of a coil. I wired it up, put it in my soft firebrick foundry and tried again. This time it made it to my desired temperature! (660.3°C, 1220°F)Feeling good I set my PID to 1200°C (2200°F). It took a while, but it was SOOOOOO worth it. My firebrick is only good for 2300°F so I didn't want to push it any further. IT FRICKEN GLOWED BRIGHT YELLOW ORANGE AND IT WAS FREAKING AWESOME.Review:It can reach 1200°, 2200°F EASY.Useful for melting copper, brass, aluminum, lead, shoes, and chocolate.Easy to stretch.Looks like a SlinkyMade my foundry bricks LITERALLY GLOW. TRY IT.
