Industrial Ceramic Parts Valve Disc

Alumina ceramic water valve discs have extremely high hardness, wear resistance, and high compressive strength, which can effectively extend the service life of the valve.With excellent anti-wear and sealing performance, it is applied to a variety of flat seals, pneumatic handturn valves and various flat seals.

Application of Alumina Ceramics
Alumina ceramics are the most common advanced ceramic materials and are also relatively traditional materials. As an excellent ceramic material, high-purity alumina ceramics have been widely used in many industries. The material has excellent properties in electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion. Therefore, alumina ceramic products are ideal for many industries, such as:

• Shafts and plungers in high wear environments
• Roller and ball bearings
• Wear-resistant linings
• Semiconductor parts
• Machine parts
• High-temperature electrical insulators
• High-voltage insulators
• Wires and wire guides
• Mechanical seals
• Basic properties of alumina ceramics

Alumina is an excellent high-temperature ceramic material due to its high-temperature stability. It is the most commonly used advanced ceramic, and the purity of alumina ceramics provided by Zhihao Ceramics ranges from 95% to 99.5%.

• Excellent electrical insulation (1×1014 to 1×1015 Ω cm);
• Medium to very high mechanical strength (300 to 630 MPa);
• Very high compressive strength (2000 to 4000 MPa);
• High hardness (15 to 19 GPA);
• Medium thermal conductivity (20 to 30 W / MK);
• Low density (3.75 to 3.95 g/cm3);
• Use temperature 1650°C without mechanical load;
• Bioinert, food compatible.
