Suitable for most FDM materials. Compatible with 1.75mm filament, including PLA/ABS/PETG/TPU/PC/PP/nylon/PEEK, etc. High hardness, more wear-resistant, Strong thermal conductivity, more heat resistant The inner wall roughness of the pipe is Ra Less than 0.4, which reduces clogging and is resistant to high temperatures. Fast heat conduction and more stable printing, Corrosion resistant, long service life Advanced heat treatment process, better corrosion resistance, extended nozzle service life Specifications: 0.2mm Material: brass colour: brass color Package Contents: 5 x Nozzle Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
