99 alumina ceramic insulation cylinder

Are you looking for insulation components with high temperature resistance, excellent insulation performance, and high mechanical strength?
Are you troubled by the problem of traditional materials being prone to aging, breakdown, or deformation in harsh environments?
Do you need customized sizes to meet special equipment or experimental needs?
99 alumina ceramic insulation cylinder is the ideal choice to meet your core needs! It provides electrical insulation, thermal stability, and mechanical support in extreme environments through ultra-high purity alumina material, and is widely used in fields such as new energy, electronics, aerospace, and high-temperature metallurgy, ensuring safe, efficient, and long-lasting operation of equipment.

99% alumina ceramic insulation cylinder is a tubular ceramic component made mainly of alumina (Al ₂ O3) with a purity of ≥ 99%, which is precision formed and high-temperature sintered. Its crystal structure is dense, with superior electrical insulation, corrosion resistance, high hardness, and thermal shock resistance. It can work stably for a long time under harsh conditions such as high temperature, high voltage, and strong corrosion, and is a benchmark material for high-end industrial insulation applications.

Core strengths

1. Excellent electrical insulation performance
   -Volume resistivity>10 ¹⁴Ω· cm, dielectric strength ≥ 15 kV/mm, effectively preventing high-voltage breakdown.
2. High temperature resistance and thermal stability
   -Long term use temperature up to 1600 ℃, low thermal expansion coefficient, and not easy to crack in sudden cooling and heating environments.
3. High strength and wear resistance
   -Compressive strength>2000 MPa, Mohs hardness level 9, resistant to mechanical impact and wear.
4. Chemical inertness
   -Resistant to acid, alkali, and molten metal corrosion, suitable for corrosive environments.
5. Precise dimensions and smoothness
   -The inner/outer diameter tolerance can be controlled within ± 0.1mm, and the surface smoothness Ra is ≤ 0.2 μ m, making it easy to integrate and install.
