Key characteristics of this component are defined by its ceramic material properties:
• Exceptional Temperature Resistance: High-grade ceramics (e.g., alumina ceramics) can withstand temperatures exceeding 1600°C, making it suitable for high-heat environments like industrial furnaces or engine systems.
• Superior Insulation & Corrosion Resistance: It effectively blocks electrical current and resists erosion from chemicals, moisture, or harsh media, outperforming many metal or plastic alternatives.
• High Hardness & Wear Resistance: The dense ceramic structure ensures long-term durability even in applications with frequent friction or mechanical stress.
Common application scenarios include precision machinery, electronic equipment (such as circuit board spacing), automotive engine components, and industrial processing equipment that requires stable performance under extreme conditions.
