Brass nozzles are the default for good reason: brass conducts heat well and machines cleanly, giving consistent flow with common filaments. Look at machining quality and the precision of the bore, since a cleanly finished orifice prevents flow inconsistencies and stringing. Confirm the thread type and length match your hotend, usually an MK8 or similar standard, and consider buying a range of sizes, from fine 0.2 mm for detail up to 0.6 mm or wider for speed. Brass nozzles suit anyone printing PLA, PETG, ABS, TPU, and other non-abrasive materials, which covers most everyday printing. They are inexpensive and easy to swap. A practical tip: keep spares on hand and treat nozzles as consumables, since a partial clog or worn tip quietly degrades print quality, and swapping in a fresh brass nozzle is often the fastest fix for mystery flow problems that resist every other adjustment.
