Polycrystalline Alumina Continuous Fiber

The Anchor series of alumina continuous fiber consists of polycrystalline fibers with a diameter ranging from 7 to 12 micrometers. It exhibits low thermal conductivity, high-temperature dimensional stability, low dielectric loss, good flexibility, excellent mechanical properties, and can withstand temperatures of up to 1100°C to 1300°C continuously, with a maximum temperature resistance of 1600°C. It meets the stringent requirements of aerospace, petrochemical, and high-temperature industrial applications.


Anchor alumina continuous fiber can be twisted, woven, or braided to produce various flexible products, including twisted yarns, woven ropes, sewing threads, woven fabrics, woven tapes, and braided sleeves. Additionally, special three-dimensional weaving structures can be used to achieve net-size shaping of customized components, meeting the application requirements of critical equipment. These flexible products can be independently used for insulation purposes and can also be combined with resin-based, ceramic-based, or metal-based materials to form rigid composite materials for applications in cables, engine combustion chambers, radar covers, and other components.


Key characteristics of Anchor alumina continuous fiber include:

  • High melting point and temperature resistance, with continuous usage temperature of up to 1300°C.
  • High strength and modulus.
  • Excellent thermal shock resistance.
  • Resistant to acid and alkali corrosion.
  • High-temperature insulation properties.
  • Low thermal conductivity.
  • High hardness and abrasion resistance.
