Features:
Alloy with High Thermal Conductivity High for High Speed Printing: The thermal conductivity of alloy is as high as 330W/m-k, ensuring that the nozzle is heated more evenly. The is twice as large as ordinary nozzles, supporting high-speed printing speed of 600mm/s.
Uniform Nickel Plating, Smoother Extrusion: The nickel-plated layer on the surface greatly reduce the adhesion of filaments to the nozzle and smoother extrusion. alloy nozzle are suitable for most other FDM materials and PEEK, PEKK PEI, PSU, PPSU and other high consumables.
Hardened Steel Nozzle: High Hardness, More Wear-resistant and Longer Service .
Hardened Steel Resists,Corrosion for Longer Service : heat process and better -oxidation are combined to prolong the service of the nozzle.
What you get: 8pcs nozzles of different sizes. 2 x 0.4mm Alloy Nozzle, 1 x 0.6mm Alloy Nozzle, 1 x 0.8mm Alloy Nozzle, 2 x 0.4mm Hardened Steel Nozzle, 1 x 0.6mm Hardened Steel Nozzle.
