This adaptor heatbreak is made of bimetal material - Copper and titanium alloy TC4. Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction. And can reach higher temperature. And We use flanged design in the end of the threaded part , which can reduce the filament leakage during printing.
With this adaptor feeding tube you can reuse all your existing V6 style nozzles Compatible with Prusa I3 MK4 and XL 3D Printers and other printers with Using Nextruder.
Heat Block Material: Copper alloy; It is machined with very high precision.This copper-alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature printing. Copper has very good thermal conductivity, The higher thermal conductivity will also slightly increase your heat-up times, and can provide tighter temperature control.
Nozzle 0.4mm is made of hardened steel material, supporting high temperature printing.
If your nozzle and heater block are not in a new condition, then you may need to hot tighten them to make sure they don't leak! Please refer: https://www.youtube.com/watch?v=OzRAVkXjw3I&t=27s&ab_channel=HobbyHoarder
