Original hardened steel nozzle for E3D V6 hot-ends.
Warning: Last items in stock!
Hardened steel nozzles are a must for highly abrasive materials. Regular brass nozzles will degrade very quickly and lose their properties.
Most of the abrasive materials are composites, plastics with something mixed in. Some examples are ColorFabb XT CF20, ColorFabb Bronzefill, ColorFabb Brassfill and some glow in the dark filaments. Always ask your filament vendor if you are not sure. Slight disadvantage is that some standard materials like ABS isn't possible to print as fast as with regular nozzle.
