Precision Machining 99.5% Al2o3 Alumina Shaft Round Ceramic Bar

The Ceramic Bar made from 99.5% alumina (Al2O3) is a high-herformance industrial component known for its exceptional hardness, wear resistance, and thermal stability. Ideal for precision machining, this round alumina shaft offers superior mechanical strength and electrical insulation, making it suitable for demanding applications in aerospace, semiconductor manufacturing, and medical equipment.

With a purity of 99.5%, the Ceramic Bar exhibits excellent corrosion resistance, maintaining structural integrity even in harsh chemical environments. Its smooth surface finish and tight dimensional tolerances ensure reliable performance in high-precision assemblies. Additionally, alumina’s high-temperature resistance (up to 1600°C) makes it ideal for furnace components and thermal processing tools.

Compared to metal alternatives, the Ceramic Bar reduces wear and extends service life in abrasive conditions. Its lightweight yet rigid properties also benefit high-speed rotating systems. Whether used as a shaft, insulator, or bearing component, this alumina ceramic bar delivers unmatched durability and efficiency for advanced engineering solutions.

Performance:

1. The strong acid and alkali resistance of zirconia ceramic shall be better than other materials.

2. Zirconia ceramics are not easy to wear, with strong durability. The hardness is close to the natural diamond and light than metals, also has the gem properties such as never wear and non - discoloring.

3. Can maintain the mechanical strength under high temperature, can be used in the condition with high temperature.

4. Good surface finish quality, could get more glossy smooth surface. Small coefficient of wear, with quite good self - lubricating function, non - magnetic, electric insulation, static - free, anti interference and radiation.

Technical Parameters

Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
