Tungsten carbide or silicon carbide? Which is the better …
2003/8/4· An engineering grade reaction bonded silicon carbide should have a hardness of 3000 to 3500 Vickers, whereas Sintered tungsten carbide might have a hardness of 1500 Vickers. An engineering grade reaction bonded silicon carbide would be more wear resistant than Tungsten carbide in puverised fuel blowing appliions in which silica grits are present, as long as the conveying …
Mechanical Seal Basics - VibrAlign
Carbon, ceramic, silicon carbide or tungsten carbide may be considered. Stationary sealing meers of Buna, EPR, Viton and Teflon are common. Pressure : The proper type of seal, balanced or unbalanced, is based on the pressure on the seal and on the seal size.
Mechanical Seals for Product Pipeline Pumps
seal face materials, such as silicon carbide or tungsten carbide, will experience less deformation compared to carbon seal faces. A car-bon seal face run against a hard face has proven to be the optimal face coination for refined products such as gasolines

Silicon nitride is optimal for engine parts due to its toughness at high temperatures, superior thermal shock resistance, light weight and corrosion resistance. Silicon Carbide Silicon carbide is the most corrosion-resistant ceramic, and is used in mechanical seals and pump parts.
Seal Reliability | Choose the right seal ring material …
2003/1/17· In any case, check the chemical compatibility of nickel and cobalt when using tungsten carbide in strong acids, as these chemicals can attack binders, causing premature seal failure. Because tungsten carbide has the highest tensile strength of any popular seal ring material, it''s applied routinely in appliions that involve high torque and vibration.

Alpha sintered silicon carbide – Mc Nally Institute
Self-sintered silicon carbide carries a slight price premium compared to the reaction bonded version. Although the preferred seal face material, it often is too brittle for some seal face designs. It is one of the most popular materials used in mechanical seal face design and is recommended in high temperature water or hot oil appliions because of its excellent thermal conductivity.
