¿Qué son los Péndulos de Impacto? Los péndulos de impacto o probadores de impacto son máquinas diseñadas para medir la resistencia de un material metálico ante un golpe o impacto repentino. Se utilizan principalmente en laboratorios de control de calidad, investigación de materiales e industria metalmecánica.

Estos equipos aplican una energía de impacto controlada mediante un péndulo que se deja caer desde una altura específica para romper una probeta estandarizada (generalmente bajo normas como Charpy o Izod). El sistema mide la energía absorbida por el material durante la fractura, lo que indica su tenacidad o capacidad de resistir impactos.
