Matsumi provides abrasive materials tailored to customer needs.

Our GC fine powder is a premium green silicon carbide (SiC) abrasive, characterized by its high purity and exceptionally hard crystal structure. Ranking second only to diamond in hardness, its hexagonal alpha-type (α-SiC) crystals maintain superior chemical stability at ambient temperatures.

A key feature of the GC series is its outstanding grinding efficiency, driven by a self-sharpening mechanism that continuously generates sharp new cutting edges during the fracturing process.Additionally, its semiconductor-like electrical properties, high thermal conductivity, and heat resistance make it an ideal material for advanced technical ceramics.

The versatility of GC fine powder enables a wide range of precision applications—from the slicing of quartz and silicon wafers to the processing of superhard alloys and cutting tools. It is equally effective for the precision lapping of soft metals like brass and copper alloys, as well as photomask glass. Beyond its use as a loose abrasive, GC serves as a high-performance component for super-finishing grinding stones and as a primary raw material for fine ceramics.
