Nozzle Materials
From soft-and-conductive (brass) to hard-and-eternal (diamondback). Hardness in HV; thermal conductivity in W/m·K.
Nozzle Diameters
Diameter sets the practical layer-height range, line width and max volumetric flow. Smaller = detail; larger = speed and CF/GF tolerance.

High-Flow / CHT Nozzles
Triple-stream and long-melt-zone designs that boost mm³/s by 20-50% over a stock nozzle, used heavily in Voron/Bambu/CoreXY builds.
Max Volumetric Flow (mm³/s, 0.4 mm)
Realistic max sustained flow before under-extrusion. Test your own with OrcaSlicer's MVS tower — these are starting points.
