High Temp Wear Resistant Alumina Ceramic Ring Flange
This 99% alumina ceramic flange is integrally dry-pressed from high-purity alumina powder, densely sintered at 1700℃, then precision processed via CNC turning, drilling and step groove fine grinding. Uniform dense pore-free body, equipped with evenly distributed counterbore mounting holes and positioning steps for tight assembly. It serves as dedicated insulating & wear-resistant annular components for high-temperature equipment, high-voltage electrical systems and fluid sealing devices. Custom non-standard sizes including outer diameter, inner diameter, hole layout and step structures are available, we accept small trial batches and mass overseas orders.
Core Advantages:
1:Excellent Electrical Insulation: High breakdown voltage, non-conductive under high temperature to avoid short circuit risks;
2:Stable High Temperature Performance: Long-term service up to 1550℃ without deformation, crack resistant under rapid thermal cycling;
3:Superior Wear & Corrosion Resistance: Mohs hardness 9, resistant to acid, alkali and organic solvents, far longer service life than metal flanges;
4:Precision Integrated Machining: Hole spacing, steps and concentricity tolerance controlled within ±0.005mm for error-free installation;
5:Low Thermal Expansion for Sealing: Stable thermal expansion coefficient, prevents gas & liquid leakage with gaskets during long-term operation.
Application
1:High Voltage Electrical Equipment: Vacuum chamber insulating flanges, power device isolation bases
2:High Temperature Industrial Furnace: Heat treatment furnace sealing support flanges, heating module insulation rings
2:Sample Support: Free small samples for testing, fast processing solution per drawings or prototypes;
3:Quality Assurance: Factory inspection reports for dimensional accuracy, insulation performance and thermal resistance;
4:International Trade: FOB, CIF, DAP terms available, stable delivery to Europe, America, Southeast Asia, Japan and South Korea.
