It is composed of 2 parts. We use a special process to hold them firmly together. You don't need to worry about it being damaged. This Heatbtreak is made from two components, Copper and Titanium TC4. Titanium TC4 reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction. The inner wall of the titanium is very smooth so that the filament can pass through and reduce clogging.
