Advantages of Ceramics Vs. Steel

When considering ceramics vs. steel components, consider that RocCera ceramic products outlast the hardest steel by 10 to 20 times with regards to service life. Our zirconia-based ceramics are the toughest ceramics known to mankind. The higher strength and higher hardness of our patented ceramic materials yield superior wear and abrasion resistance as well as superior corrosion resistance.

Technical Advantages

  • Higher strength
  • Higher hardness
  • Superior wear and abrasion resistance
  • No corrosion – Ever
  • Electrical insulators (oxide ceramics)
  • Best thermal insulator – zirconia
  • Withstands high temperature (> 1000°C)
  • Withstands thermal shock

Cost Advantages

  • Replacing worn steel parts less frequently lowers total cost of ownership in both labor and replacement parts cost.
  • Net-shape ceramic manufacturing, however, can lower the cost by almost 50% for many applications by eliminating or reducing the cost of hard machining using diamond tooling.
  • If dimensional tolerance is not stringent and for medium to high volume manufacturing, e.g., over 100 parts per week, ceramic can be competitive.
  • For high volume requirements, ceramics can be injection molded. This lowers the cost to the level of stainless steel.

Performance Advantages

  • Typically, ceramics outperform steel by at least 10x
  • RocCera’s oxide-based ceramics do not corrode, whereas steel parts do corrode
  • Our ceramics can withstand higher temperatures without compromising the strength
  • Alumina and zirconia ceramics are superior electrical insulators
  • Zirconia ceramics are the best thermal insulators
  • RTZ ceramic has low coeff of friction, μ (0.1 – 0.3) requiring no lubrication as contrasted to steel.
  • Under high load, steel against steel is prone to galling – ceramic does not gall
  • For specialized applications, steel requires an additional processing step to improve the surface hardness
