Chromium Zirconium Copper High-Flow 0.4mm Nozzle for Ender 3 V3 SE

The Chromium Zirconium Copper (CrZrCu) High-Flow 0.4mm Nozzle is a premium upgrade designed specifically for high-speed 3D printing on modern platforms like the Creality Ender-3 V3 SE, Ender-5 S1, and Ender-7. Engineered from a high-performance chromium zirconium copper alloy, this nozzle offers exceptional thermal conductivity that far exceeds standard brass and hardened steel. This superior heat transfer ensures rapid and uniform melting of the filament, effectively eliminating extrusion bottlenecks during high-velocity printing.

Featuring an advanced internal high-flow geometry (tri-hole insert design), this nozzle splits the incoming 1.75mm filament into three distinct paths. This significantly increases the surface area in contact with the heated nozzle walls, allowing for a much higher volumetric flow rate. It is highly compatible with standard filaments like PLA, ABS, PETG, and TPU, as well as high-temperature engineering materials. The precision-machined M6 thread and ultra-smooth inner bore (Ra < 0.4) minimize friction and prevent clogging, making it a reliable choice for makers and professional engineers seeking flawless high-speed prints.

Features:

• Superior Thermal Conductivity: Chromium Zirconium Copper alloy delivers ultra-fast heat transfer for consistent melting at high speeds.
• High-Flow Tri-Hole Design: Internal geometry splits the filament to maximize heat absorption and boost volumetric flow.
• High Temperature Resistance: Safely handles continuous printing temperatures up to 450°C, perfect for advanced engineering plastics.
• Precision Machined Bore: Smooth inner wall with a roughness of Ra < 0.4 reduces filament drag and prevents clogs.
• Enhanced Wear Resistance: Offers significantly better durability and lifespan compared to standard brass nozzles.
• Seamless Compatibility: Designed to fit Creality Ender-3 V3 SE, Ender-7, Ender-5 S1, and Spider high-flow hotends.
