Alumina Ceramic Components: Economical And Reliable Industrial Fixing, Insulation, And Connection Solutions

Introduction
Alumina Ceramic Components, including fixing brackets, insulating plates, and structural connectors, are key functional parts manufactured from high-purity alumina (Al₂O₃) material. As the most widely used advanced industrial ceramic material, they excel in industrial applications requiring excellent electrical insulation, good mechanical strength, and high-temperature resistance. These components, with their excellent cost-performance ratio and stable performance, serve as an ideal choice for power electronics, semiconductors, medical devices, and automation equipment.

Core Advantages

  • Excellent Electrical Insulation: Extremely high volume resistivity and dielectric strength, maintaining outstanding insulation characteristics even in high-temperature environments

  • Outstanding Mechanical Strength: High hardness and compressive strength, capable of withstanding significant mechanical loads and wear

  • Good High-Temperature Resistance: Can operate stably for extended periods in high-temperature environments up to 1600°C

  • Excellent Chemical Stability: Resistant to acid and alkali corrosion, with superior oxidation resistance

  • High Cost-Effectiveness: Lower manufacturing costs compared to other advanced ceramics

Primary Applications

  • Electronics and Power Industry: Circuit board supports, insulators, switch components

  • Semiconductor Manufacturing: Process fixtures, carrier plates, insulating spacers

  • Medical Devices: Equipment insulation components, instrument brackets

  • Industrial Automation: Robotic arm accessories, sensor protection covers

  • High-Temperature Equipment: Furnace accessories, thermal instrument protection sleeves

Manufacturing Process

  1. Raw Material Preparation: Selection of high-purity alumina powder

  2. Forming Process: Dry pressing, isostatic pressing, or injection molding

  3. High-Temperature Sintering: Sintering and densification at 1600-1800°C

  4. Precision Machining: Grinding and polishing using diamond tools

  5. Quality Inspection: Strict dimensional and performance testing

  6. Surface Treatment: Polishing or metallization as required

Usage Instructions

  • Avoid impact with sharp objects during installation

  • Consider differential thermal expansion when mating with metal components

  • Keep surfaces clean and avoid oil contamination

  • Regular inspection when used in corrosive environments

  • Avoid rapid temperature changes

After-Sales Service

  • 12-month quality warranty

  • Technical support and consultation

  • Free replacement for non-human damage

  • Rapid response to customer needs

  • Customized solutions

FAQ

 

 

  1. Q: What is the difference between alumina ceramic and silicon nitride ceramic?
    A: Alumina ceramic offers better insulation and lower cost; silicon nitride ceramic provides higher strength and better toughness.

  2. Q: What is the maximum service temperature?
    A: Long-term use up to 1600°C, short-term use up to 1800°C.

  3. Q: Can it be machined?
    A: Yes, but requires diamond tools for machining.

  4. Q: What surface roughness can be achieved?
    A: Can achieve Ra 0.2μm after polishing treatment.
