I have a Lulzbot Taz 6, and I am wondering what material the nozzle tip is made from. I hear many people refer to it as a brass nozzle tip. But I am wondering if it is indeed brass or if it is copper? I have attached two different PDF’s that indicate the material could be made of either brass or copper. The ‘nozzle_3mm-0.5mm_v0.2’ file is from the devel.lulzbot page, and this indicates that the nozzle is made of copper. The other file shows that some nozzles can be made of copper while others could be made from brass.
I’m curious because the thermal conductivity is quite different between copper and brass.
