Boron Carbide Abrasive Grains, Turbocut

Tough Products offers Turbocut Boron Carbide Abrasive Grains. Turbocut boron carbide is one of the hardest materials ranking third behind diamond and cubic boron nitride and far superior than conventional silicon carbide and aluminium oxide. Turbocut boron carbide is produced by reacting carbon with B2O2 in an electric arc furnace, through carbo thermal reduction, which is then milled and purified by state of the art water purification method to remove graphite, dust, SiO2, sodium, potassium and other water soluble impurities. Iron precipitates out leaving high quality turbocut boron carbide powder. Boron carbide is one of the hardest man made materials available. Above 1300ºC, it is even harder than diamond and cubic born nitride. It has a 4-point bending strength of 35-50 kg/mm² and a compressive strength of 290 kg/mm² depending on density. Boron carbide also has a low thermal conductivity (29-67 W/mk) and has electrical resistivity ranging from 0.1-10 ohm-cm. With its strength to weight ratio and low thermal conductivity, it is ideal for a wide variety of applications. Thermal neutron capture cross section is 600 bam. Grit sizes available: grains – # 80, 120, 150, 180, 220, 240, 280, 320, 360, 400, 500, 600, 800, 1000 and 1200. Packaging: standard packings of 200, 500, 1000 and 2000 gm. Applications: aerospace; ballistic armor; blasting composites; ceramic composites; honing stones; lapping; metal matrix composites; nuclear technology; refractory shapes, cements; tool and die fabrication; ultrasonic machining; boronizing. Examples: lapping and polishing of hard metal carbides; ceramic parts – hot pressed or cold pressed and sintering to make blasting nozzles, crush rolls and wear parts; refractory antioxidant in castables and cements; hard facing welding electrodes and coatings; composite reinforces aluminium casting; nuclear pellets, control rods absorbs stray neutron in nuclear reactor, also in rocket propellants and armored plates; slurry sawing, marbles polishing; boronizing a case hardening heat treatment for wear parts and tools, etc.
