PDC cutters for oil and gas drilling: a polycrystalline diamond layer integrally sintered to a cemented carbide substrate, delivering abrasion resistance and impact toughness in demanding downhole environments. Diameters from 8 mm to 19.05 mm.
Polycrystalline diamond compact (PCD) blanks: a synthetic polycrystalline diamond layer bonded to a cemented carbide substrate under ultra-high pressure and temperature, combining the wear resistance of diamond with the toughness of carbide. Coarse, medium and fine grain grades from 1 μm to 25 μm.
PCBN composites sintered from cubic boron nitride powder onto a carbide substrate. Hardness second only to diamond with red hardness up to 1,400 °C for high-speed dry cutting of hardened steel and cast iron — turning instead of grinding. CBN content from 50% to 95%.
Diamond-copper thermal composites provide high heat spreading with low thermal expansion and light weight, keeping high-power chips, lasers and RF devices stable under growing thermal loads. Discs, blocks and custom shapes per drawing.
