This blog, not just rates rate a particular type of seal face higher to the other, but it gives a comprehensive analysis of the silicon carbide vs tungsten carbide mechanical seal. Thus, a user may pick the most suitable seals for the appliion.

Supreme Wear Properties - Syalon vs Tungsten Carbide

Syalon 050 vs Tungsten Carbide. Tungsten carbide (WC) is a well-established material for shot blast nozzles, but International Syalons has demonstrated the superiority of Syalon 050 for such high intensity wear appliions. Tungsten carbide offers high toughness and hardness due to its microstructural arrangement of high strength carbide grains.

Silicon Carbide vs. Tungsten Carbide Hard Sealing …

2019/9/26· Silicon Carbide out performs Tungsten carbide as hard faces in most seal appliions. It’s tribological properties allows for lower coefficient of friction and longer life. In heavy slurry or other extreme pumping conditions the properties are enhanced when you match silicon carbide with a silicon carbide impregnated with graphite (check with your Priest Electric Seal Specialist).
