Tungsten Carbide 3D Printer MK8 Extruder Nozzle, High Temperature Printing, Super Wear Resistant, 0.4mm/1.75mm

Extreme Durable: Hardness of 9 Mohs, the same as Ruby nozzle, it provides highest hardness and far superior to ordinary hardened steel nozzle, so it could ensure continuous printing without replacing nozzle, especially printing with filament such as Carbon Fiber, PEEK, etc
High Temperature Resistance: Temperature resistance up to 550, which is the same as copper plated nozzle, but Tungsten nozzle is more wear-resistant than copper plated nozzle
Good Heat Conduction: Thermal conductivity of 130W/m·k, much better than Rubby nozzle(45W/m·k) and hardened steel nozzle(26W/m·k), the better thermal conductivity greatly speeds up filament melting speed in hot zone
Low Expansion: Expansion coefficient of 4.5 m/m·, much lower than copper plated nozzle( 16.7 m/m·), so it can adapt to continuous high temperature printing without deformation, especially when printing large-scale molds
Compatibility: These 3D printer nozzles compatible with MK8 hotend of Ender / CR series 3D printers. Also compatible with CR-10 all-metal hotend, Prusa i3, Anet A8, Reprap, etc
