  • Silicon Carbide (SiC)
    Silicon carbide (SiC) is a compound of silicon metalloid and oxygen usually used in the alpha silicon carbide structural form.  SiC is a black, high hardness ceramic that usually is harder than alumina.  Depending on the Impurity additions, silicon carbide is green or black in color. Fully dense
  • Precision Parts in CVD Silicon Carbide
    graded silicon carbide due to its outstanding thermal conductivity of over 250 W/mK, which is more equivalent to iron or steel, yet offers extreme hardness and wear resistance, even at high temperatures. This material machines well using diamond grinding technology, and there is no real cost penalty
  • Milling Nickel-based Alloys - Milling Heat Resistant Alloys
    WG-300 is successfully used for the turning of hard materials other than Nickel-based alloys in the range of 45-65 Rc. The outstanding hardness, combined with the high strength imparted by the reinforcing silicon carbide whiskers, makes possible the machining of many materials previously workable
  • AN0016 Micro-sectioning of Multilayer Ceramic Capacitors
    will almost certainly generate damage around the chip edges during grinding. Consequently use of a high quality, low stress potting compound is recommended. Waterproof Silicon Carbide grinding paper is available in many grit sizes. Paper should be selected as appropriate to the sample being prepared
  • Alumina
    resistance due to its higher coefficients of thermal expansion and lower thermal conductivity compared to other pure ceramic materials such as silicon carbide (SiC).
  • Cast Iron
    excellent machinability (even at wear-resisting hardness levels), damps vibration, and aids lubrication on wearing surfaces (even under borderline lubrication conditions). When most of the carbon remains combined with the iron (as in white iron), the presence of hard iron carbides provides good abrasion
  • The Metallurgical Effects of Weld Seam Heat Treating (.pdf)
    way to relieve the strain is to reheat the steel to a temperature. below that which will cause the formation of austenite. This process is called tempering. It. allows the carbon atoms to escape from the iron crystal lattice and recombine to form carbides. This reduces the hardness and improves
