Resumo
Most of the alloys used as bonding matrix in diamond tools show a high content of cobalt - which is undesirable due to a series of reasons. In the last decade, some attempts were made towards the reduction of the Co content in these alloys. NEXT 100® alloy (25.2%Fe- 49.5%Cu-24.1%Co) by Eurotungstene is an example of it. This study aims to characterize some mechanical properties of the NEXT 100® - this is a comercial alloy widely used as bonding matrix for diamonds in cutting tools, and the informations about its properties are scarce in the literature. The metallic powders were hot pressed in a graphite matrix at 35MPa/800°C/3 minutes. In these sintered samples, it was made wear resistance and hardness HRB tests. Densification and compression test were performed. It was determined that the NEXT 100® alloy obtained by hot pressed has good mechanical properties and high densification.
