Worldia Profile

Cubic boron nitride is the second hardest material in the world developed successfully in 1957; the micro-hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV2500-5000, so CBN is considerably more abrasion-resistant than tungsten carbide and ceramics. With a high oxidation resistance within 100℃, CBN will not create any chemical reaction with ferrous material in 1200-1300℃. For this reason, CBN is an ideal option when it comes to performing of dry cutting operations on ferrous metals. The applications of CBN cutting tools include: cutting hardened steels, cast irons, sintered irons as well as powder metallurgy components.
