This work presents a failure analysis performed on a clay extruder nozzle used in a brick factory in order to observe if the material is suitable to withstand the conditions to which it is exposed. The extruder nozzle responsible for shaping the ceramic blocks had wear generated by excessive abrasion, thus increasing production costs. A methodology was designed to determine the cause of failure and propose the appropriate material for the nozzle through a study based on forensic engineering. Samples of the clay paste and the nozzle material were selected, which were characterized physically and chemically by hardness tests, metallography, spectrometry, X-ray diffraction, and scanning electron microscopy.
