Core Selling Points:

1. Feature: High Purity Alumina Material (99%/99.5%)
Advantage: Ultra-low impurity content eliminates performance degradation at extreme temperatures, ensuring

consistent chemical stability and high dielectric strength.
Benefit: Your equipment maintains reliable electrical insulation and corrosion resistance in high-temperature furnaces,

semiconductor processes, and vacuum systems, reducing maintenance costs and extending service life.
2.Feature: Precision Machined Tolerances & Custom Design
Advantage: CNC-machined to tight tolerances (±0.01mm) with pre-drilled mounting holes and a stepped inner profile,

ensuring seamless fit with mating components.
Benefit: Eliminates the need for on-site modification, enabling quick and hassle-free installation in custom assemblies,

reducing downtime and assembly errors.
3. Feature: Excellent High Temperature & Thermal Shock Resistance
Advantage: Sintered at temperatures above 1600℃, the flange ring withstands continuous operating temperatures up

to 1600℃ and rapid thermal cycling without cracking or warping.

Benefit: Ideal for use in high-temperature furnaces, kilns, and thermal processing equipment, providing long-term

structural stability under extreme heat conditions.
4.Feature:Superior Electrical Insulation Performance
Advantage: High dielectric strength (>15kV/mm) and low dielectric constant ensure no electrical leakage or short-circuit

risks in high-voltage environments.

Benefit: Protects sensitive electronic components and prevents electrical failures in power electronics, semiconductor

manufacturing, and high-voltage equipment.
5. Feature: Outstanding Wear & Corrosion Resistance

Advantage: Hardness up to HRA 88-92, resistant to abrasion, chemical corrosion, and oxidation, even in harsh acidic/alkaline environments.

Benefit: Reduces wear-related component failure in mechanical sealing, fluid handling, and chemical processing applications, minimizing replacement frequency.
6. Feature: Customizable Sizes & Specifications

Advantage: Available in multiple outer/inner diameters, thicknesses, and hole configurations; supports custom

drawings for OEM/ODM projects.

Benefit: Meets unique design requirements for your specific equipment, whether standard or non-standard dimensions, ensuring perfect compatibility with your system.

Common Applications:
