GC, green silicon carbide, is a very high purity SiC lapping powder. GC is well suited for use as a lapping powder in a wide range of functions, including the precision lapping and dicing of crystal and ferrite, the slicing of Si ingot, and the processing of materials ranging from ultra hard metals and edged tools to soft metals such as brass and other copper alloys. C is a black silicon carbide lapping powder, commonly known as Carborundum. Because of its stable cutting edges and its ideal particle size distribution, it is used for abrasive machining. The unique abrasive character of C makes it possible for superior lapping to be done on a work surface. C is ideal for use as a material of precision lapping polishing clothes and papers, and finishing precision grind-stones
