Zirconia Ceramic Ring Ceramic Ring Precision Wear - Resistant
Product Overview
Weite ceramics is a professional manufacturer of zirconia ceramic
rings. Zirconia ceramic ring has high toughness, heat resistance,
corrosion resistance, wear resistance, zirconia precision ceramic
parts material is high insulation layer and other metal materials
and plastic incomparable characteristics.
Ceramic sealing rings for mechanical construction are superior to
other materials in terms of chemical resistance, wear resistance,
and high temperature resistance. It is made of ceramic powder
through vacuum hot pressing sintering, grinding, polishing and
other processes. It is widely used in the harsh conditions where it
is difficult to use metal or other materials in the fields of
machinery, chemical industry, petroleum, food, pharmaceuticals, and
automobiles.
The difference between alumina ceramic ring and zirconia ceramic
ring:
The ductility of the zirconia ceramic ring is 4 times that of the
alumina ceramic ring. For example, the zirconia ceramic ring and
the alumina ceramic ring fall from a height of one meter. The
zirconia ceramic ring has only a small gap, while the alumina
ceramic ring The ring will shatter.
The wear resistance of zirconia ceramic rings is 15 times that of
alumina ceramics, the friction index of zirconia ceramics is only
half of that of alumina ceramics, and the friction index of its own
alumina ceramics is lower. Secondly, the relative density of the
zirconia ceramic ring is higher. After grinding and polishing, the
color is bright and clean, which is mirror glass and the friction
resistance is smaller.

Product advantages
- High temperature resistance
- preservative
- Demagnetization
- Long service life
Due to the characteristics of industrial ceramic rings, it is more
heat-resistant, corrosion-resistant, and wear-resistant than
traditional metal material industrial production rings and the raw
materials will not pollute the environment. It has been warmly
welcomed by more and more manufacturers, and has already changed.
It has become an indispensable part of the industrial production of
processing plants such as traditional industrial production and
manufacturing, R&D and manufacturing of innovative
technological products.
Applications
- Shipbuilding, bridges, large-scale structural facilities
- Lighting industry
- Electronics and electric heating industry
Product Picture
Zirconia ceramics have phase transformation toughening and
micro-crack toughening, so they have high strength and toughness.
They are known as "ceramic steel", and its fracture toughness is
the highest among all ceramics.
