Silicon Carbide Abrasives: The natural mineral form of silicon carbide is long, thin and very sharp, so when thinking about silicon carbide abrasives think of a belt or disc covered in thousands of tiny, but very sharp knives. So why are silicon carbide abrasives not
What Is Induction Melting & How Does It Work? | Arell
The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
