PTFE (Teflon) vs Peek — High-Performance Plastic Comparison for Extreme Environments

Last updated: April 21, 2026

When printing with standard filaments like PLA or PETG, a brass nozzle performs well. However, abrasive filaments containing carbon fiber, glass fiber, or metal particles will rapidly wear through brass, causing dimensional inaccuracies and eventual print failure.

What Makes Filaments Abrasive

Carbon fiber reinforced filaments are highly abrasive with fiber hardness around 200 HB. Glass fiber is even harder at 500 HB. Metal-filled and glow-in-the-dark filaments also cause rapid wear. Our PA6-CFフィラメント is optimized for reliable printing.

Nozzle Materials Compared

Brass nozzles (hardness 55-100 HB) last 10-50 hours with CF filament. Hardened steel (700-900 HB) provides 200-500 hours of use. Ruby nozzles (1500+ HB) offer unlimited wear life for production environments.

Print Settings for Hardened Nozzles

Increase temperature by 5-10°C vs brass due to lower thermal conductivity. Extrusion may need 2-5% more flow. First layer settings may require adjustment.

3D Printing Nozzle Selection — Frequently Asked Questions

How long does a brass nozzle last with carbon fiber filament?

A standard brass nozzle lasts only 10-50 hours when printing with carbon fiber reinforced filament. Highly filled CF30 (30% carbon fiber) can destroy a brass nozzle in under 10 hours. Ruby nozzles can print thousands of hours with CF filament without measurable wear.

What nozzle material should I use for abrasive filaments?

Hardened steel nozzles (700-900 HB) provide 200-500 hours of reliable service with CF and GF filaments. Ruby nozzles (1500+ HB) offer essentially unlimited wear life for production environments.
