Eixo de carboneto de silício resistente ao desgaste

Carboneto de silício (SiC) ceramics have excellent characteristics such as strong oxidation resistance, Hexagonal, high thermal stability, high temperature strength, small thermal expansion coefficient, alta condutividade térmica, thermal shock resistance and chemical corrosion resistance. Portanto, it is widely used in petrochemical, metallurgical machinery, aeroespacial, microeletrônica, automobiles, steel and other fields, and gradually shows advantages that other special ceramics cannot match.

Recursos

The technical properties of silicon carbide are remarkably similar to those of diamond. It is one of the lightest, hardest and
strongest technical ceramic materials and has exceptional thermal conductivity, chemical resistance and low thermal expansion.

* Extremely high hardness
* Wear resistant
