Carbure de silicium noir pour abrasifs
Le carbure de silicium noir est un matériau très durable et tranchant, connu pour sa dureté et sa conductivité thermique extrêmes. Il est couramment utilisé dans les applications nécessitant une coupe, un meulage ou une finition de surface efficaces, en particulier sur les matériaux durs tels que les céramiques, les métaux et le verre. Sa grande résistance à l'usure et à la chaleur le rend également précieux dans les industries des abrasifs et des réfractaires.
