Thanks to its low-cost production, the nozzle has a wide range of applications and is therefore very popular in the 3D world! The nozzle is made with a special processing technology and is carefully manufactured, which means that it has no burr on the tip edge and no inconsistencies in the bore. The low roughness of the inner bore ( Ra 0.4 m) and a layer of brass ensure excellent smoothness and only low adhesion. The material conducts heat excellently, does not corrode and permanently retains its shine! Features:M4 threadTemperature resistance up to 300 °CThermal conductivity 105 W/mkExpansion coefficient 18 m/m
