Advantage:

Advantages:


1)High purity and superior function.
2)Good flateness and high precision in size.
3)Strong production capacity.
4)High qualification rate.
5) There are no fragile plates because we use high strength alumina ceramic.

Application:

★ Laboratory analysis and various industrial analysis, metal and nonmetal material sample melting.

★High temperature application, such as metal processing, glass melting, rapid thermal cycling, gemstone purification for jewelry industry.
★Widely applied in the metallurgy, chemical industry and materials science, etc.

Composition:

Alumina content ranges from 60% to 99.9%, with higher purity grades (e.g., 99.7%) offering superior hardness,thermal stability, and electrical insulation.

Thermal Resistance:

Withstands temperatures up to 1650°C, making them ideal for high-temperature applications like furnace tubes and thermocouple insulation.

Mechanical Strength:

High compressive strength (~2500 MPa) and Vickers hardness (11-14 GPa) ensure durability in abrasive environments.

Electrical Insulation:

Dielectric strength and low electrical conductivity suit electronics and vacuum systems.
Ceramic screw and nuts refers to the ceramic screw is made of zirconia, alumina, silicon nitride and other materials of screw products,which has more stable physical stability and chemical stability, physical stability is mainly manifested in high and low temperature resistance, insulation, antimagnetic, wear resistance and other aspects; Chemical stability of the main surface in corrosion resistance, oxidation resistance. However, because it is a hard and brittle material, its mechanical properties can not be compared with metal materials. Of course, with the progress of material technology and the improvement of product structure, this gap is gradually narrowing.
