Maximize Your Print Quality with High-Flow Brass Nozzles If you are printing with standard filaments like PLA or PETG, brass is the gold standard. While steel is great for tough materials, it struggles to move heat quickly. Our Premium Brass Series for the Elegoo Centauri Carbon is designed for users who prioritize speed, surface finish, and reliable flow. The Choice for High-Speed Printing Brass reaches the target temperature faster and maintains it more consistently during high-speed moves. This results in better layer adhesion and a glossier finish on your final parts. If you aren't printing abrasive "filled" filaments (like carbon fiber), these brass nozzles will provide a superior printing experience over hardened steel. Technical Specifications: Material: High Quality Brass Thermal Conductivity: ~115 W/m·K (vs. ~15-30 for Steel) Output Diameter: 0.4mm Input Diameter: 1.75mm Compatibility: Elegoo Centauri Carbon / CC / CC2 Quantity: 5 Pieces Maintenance Tip: Brass is softer than steel, which makes it easier to clean but also susceptible to wear if used with "glow-in-the-dark" or wood filaments. For everyday PLA and PETG printing, these are the most reliable and cost-effective nozzles you can buy.
