It is named "Bi-Metal Heatbreak" It has two components with different thermal conductivity. 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.

Can be used with printers that have 8mm Leadscrew and 5mm Motor Shaft

Package: 2pieces coupler
