• NKR® fibers

    Neoker manufactures the NKR® single crystal alumina fibers for reinforcement of high performance composites.

  • “Less of NKR® fibers are needed to produce higher improvements, compared to other alternatives”,

    Director of R&D in Chemical company (Fortune 500)

  • How are the NKR® fibers?

    • Single Crystal Fibers
    • Pure
    • Grown in the c-axis direction
    • Of alpha-alumina (corundum)
    • With a very high aspect ratio

  • “Adding a 2.5% of NKR® fibers to our refractories, we got a 100% increase in mechanical performance…”,

    Technical Dept. of Technical Ceramics Company

  • “I have a good feeling about the NKR® fibers as our first experiences showed very interesting performance. We have decided to undertake a second level evaluation (bench and field tests)…”,

Uses of NKR® fibers

NKR® fibers are indicated for:

  • Aggressive environments (acids or bases).
  • Combustion environments (engines, turbines ...).
  • A wide range of working temperatures (low and high temperatures).
  • Improved creep resistance in MMC's and CMC's.
  • Increased hardness and abrasion resistance.
  • Improved impact resistance.
