UniTak3D I3 Mega S Bi-Metal Heatbreak All Metal Smooth TC4 Titanium Alloy Copper Plated Throat Nozzle Compatible with Anycubic I3 Mega S, Chiron, Vyper 3D Printers(Pack of 2Pcs)

【All-metal Heat Break】:Made of harder and more wear-resistant material,the all metal heat break works well with high-temp filaments(resistance up to 420℃).

【Bi-Metal Design】: This all metal heatbreak is made of Titanium Alloy and Gold-plated Copper.Titanium alloy is used to reduce heat conduction upward from the heating block, and gold-plated copper is used to accelerate heat conduction.

【Nicely Machining】:The inner surface is smooth and free of burrs; Compared with ordinary heatbreak,the resistance of the printing retraction is largely reduced, thus the printing result is much more precise and delicate.
