Avejjbaey for Ender3S1 Titanium-Alloy Bi-Metal Heatbreak Copper-Alloy Heat Break M6x26mm for 3D Printer 1.75mm Filament M6 26mm Printer Accessories MK8 Throat Bi-Metal Copper Alloy E3DV6 Bimetal Hose

brass, temperature resistant, and long service. The thermal barrier performance is better than that of original and the printing quality is improved. The Inner wall of the for is very smooth so that the filament- can pass through and reduce clogging. for Titanium-alloy is used in the front part to reduce thermal conductivity, while copper-alloy is used in the back part to help heat dissipation. Two kinds of metals are used to make the throat tube."Bi-Metal Heatbreak" It has two components with different thermal conductivity.
