Has lots to offer, and even more depending on copper content. NHT’s brand name for sintered tungsten-copper is EROMET. It is predominantly manufactured with a tungsten:copper ratio of 80:20, 75:25 and 90:10.
EROMET is characterized by good machinability, high burn-off resistance, and by its outstanding electrical and thermal conductivity.
Applications for EROMET include sinking electrodes for spark erosion (EDM) and high-voltage and low-voltage switching contacts in electrical switchgear applications. Its principal properties include high temperature resistance, caused by the tungsten matrix, and the electrical and thermal conductivity, caused by the infiltrated copper content.
