QIDI BMN204 0.4mm Bimetal Nozzle for Q2 Series (2 pcs) – Copper/Titanium Alloy, M6 Thread, 1.75mm Filament

For QIDI Q2 Series owners who demand more from their hotend, the BMN204 bimetal nozzle replaces the stock brass unit with a copper alloy tip and titanium alloy heat break. This pairing delivers rapid, uniform heat transfer while drastically reducing heat creep—a common cause of clogs and inconsistent extrusion. The result is a nozzle that handles abrasive and high-temperature filaments with confidence, maintaining stable flow even during marathon prints.

Highlights

• Bimetal construction: copper alloy tip for high thermal conductivity, titanium alloy heat break to minimize heat creep
• 0.4 mm nozzle diameter – the standard for detailed, high-quality prints
• High wear resistance, supporting abrasive materials such as carbon fiber, glass fiber, and metal-filled filaments
• Ultra-smooth inner surface reduces clogging and ensures steady extrusion
• M6 thread – easy screw-in installation compatible with V6-style hotends
• Package includes 2 nozzles for convenient replacement

In daily use

Upgrading to the BMN204 nozzle is straightforward: simply unscrew the old nozzle, clean the mounting surface, and screw in the new one with the appropriate torque. The titanium heat break keeps heat in the heater block, so your cold-end stays cool and filament flows reliably. With a maximum printing temperature of 450°C, you can confidently print high-temperature materials like PEEK and PEI, while the copper tip provides responsive heating for precise temperature control. Whether you're working with standard PLA or abrasive composites, this nozzle maintains consistent extrusion and reduces the need for frequent replacements.
