 | JRCD-A Features: Processed from破碎料JCD-A through shaping and other techniques, this product boasts regular crystal shapes, nearly isometric oval or spherical particles, low impurities, low magnetism, and a rough surface. Applications: Primarily used in the production of heavy-duty ceramic bonded grinding tools, medium-load metal bonded grinding tools, and electroplated grinding tools, suited for machining non-metals such as glass, ceramics, and stone. Offers higher strength and better wear resistance compared to JCD-A, and excellent economy and grinding properties compared to primary mono-crystalline fine powder JSD30. |
 | JRCD-B Features: Derived from破碎料JCD-B through shaping and similar processes, it presents with uniform crystal structures, near-isometric oval or spherical grains, minimal impurities, low magnetic response, and a coarse surface. Applications: Mainly utilized in the manufacturing of medium-load ceramic and metal bonded grinding tools, as well as electroplated tools, ideal for non-metallic materials like glass, ceramics, and stone. Outperforms JCD-B in terms of strength and wear resistance, and provides favorable economics and grinding efficiency when compared to native single crystal fine powder JSD20. |
 | JRCD-C Features: Manufactured based on破碎料JCD-C through整形and additional procedures, it exhibits consistent crystal patterns, particles resembling isometric ovals or spheres, low levels of contaminants, negligible magnetism, and a roughened exterior. Applications: Suited primarily for heavy-resin bonded, medium-ceramic bonded, and light-metal bonded grinding tools, effectively processing gems, glass, optical glass, ceramics, stone, among other non-metals. Offers enhanced strength and wear resistance over JCD-C, and represents a cost-effective and efficient alternative to original mono-crystal fine powder JSD10. |
