BZ 3D Ender 3 CR 10 Bi Metal Heatbreak,Ender V2 All BiMetal Heatbreak for 3/V2/Pro/Ender 5/Plus/CR 10/10S/S4/S5/CR V2/V3/Neptune 3/Pro/Plus/Max/Neptune 4/Pro Printer Hotend.(2PCS)

This is a branch design of the bimetal HEATBREAK. Its thermal blocking front end is made of titanium alloy and the back end is made of copper alloy material. It has a strong thermal blocking ability. For 1.75mm Filament. Titanium alloy reduces heat upward conduction at the heating position, and copper for heat dissipation to accelerate heat conduction.We use a special process to hold them firmly together. You don't need to worry about it being damaged. Compared with competitive products, The inner wall of the tube is smoother (reducing the chance of filament clogging).The interface is smoother and more precise (can effectively prevent the filament from leaking). Replacement with advanced machines for processing.modified heat treatment method.Strict quality assurance.No burrs,anti-oxidation and clean surface. Compatible with Ender 3,Ender 3 Pro,Ender 3 V2,Ender 3 Max,Ender 5,Ender 5 Pro,Ender 5 Plus,CR-10,CR-10S,CR-10 S4,CR-10 S5,CR-10 V2/V3,CR-10 Mini,Neptune 3 Pro/Plus/Max/Neptune 4/4 Pro 3D Printer Hotend.
