High Temperature Resistance and high strength 95% Alumina Ceramic rod
1. Description
Alumina is the most cost effective and widely used material in the family of engineering ceramics. The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes. With an excellent combination of properties and an attractive price, it is no surprise that fine grain technical grade alumina has a very wide range of applications.
2. Typical Alumina characteristics include:
- Good strength and stiffness
- Good hardness and wear resistance
- Good corrosion resistance
- Good thermal stability
- Excellent dielectric properties (from DC to GHz frequencies)
- Low dielectric constant
- Low loss tangent
