Description

 

High Precision Machining Al2O3 Ceramic Bushing

 

 

Properties of Al2O3 Ceramic Bushing:
  • Very high compressive strength (2,000 to 4,000 MPa)
  • High hardness (15 to 19 GPa)
  • Low density (3.75 to 3.95 g/cm3)
  • Operating temperature without mechanical load 1,000 to 1,500°C.
  • Moderate thermal conductivity (20 to 30 W/mK)
  • High corrosion and wear resistance
ceramic bushingThe advantages of Al2O3 Ceramic Bushing:

1.Thermonstability

Working temperature of high alumina ceramics can be as high as 1400 degree celsius.

2.Good self-lubricity

Hgih alumina ceramics have the properties of self-lubricity and inadhesion, the roughness is only 1/6 that of steel pipes thus less flow resistance.

3.High hardness

Rockwell hardness of high alumina ceramics is up to HRA80-90 which is second only to diamond and far exceeds wear-resistant steel and stainless steel.
