Advantages:
1.Withstand high temperature: with high melting point, high boiling
point characteristics, can be used under high temperature is not
affected.
2.Not easy to corrode: not affected under strong acid, strong
alkali, inorganic and organic salt conditions.
3.Antimagnetic: Because the product material is non-magnetic, it
does not absorb dust, which can reduce surface peeling.
4.Electrical insulation: it is an insulator at room temperature
with high resistivity, which can be used in equipment requiring
insulation.
Application:
1.Gas laser tubes.
2. Electronic substrates.
3.Seal rings.
4. High temperature electrical insulators.
5. High voltage insulators.
6.Thermometry sensors.
