MK10 hotend structure only allows filament to have little contact with the nozzle. The material of the nozzle must be brass to ensure filament's temperature is the same as the thermistor, so it make the melt plastic more smooth. But the heat conductivity of stainless steel is so poor, it is unscientific and irrational used on MK10 nozzle.Material: Nozzle is brass. Throat is stainless steel. Heater block is aluminium alloy.Colour:As shownMaterial:metalPackage Contents:1 x 0.4mm M7 brass nozzle1 x 1.75mm stainless steel throat1 x 34mm PTFE tube1 x Aluminum heating blockOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
