2.Stainless steel: wear-resistant and corrosion-resistant
3.Hardened steel: high hardness, wear resistance, and longer service life
 
Product Usage:
1. The nozzle selection needs to be based on the printing situation. If consumables such as PLA/PETG are generally printed normally, it is recommended to use a brass nozzle.
2.If using consumables with particles such as carbon fiber, it is recommended to use hardened steel or stainless steel nozzles for printing.
