Properties of Alumina Ceramic parts:

  • Excellent Electrical Insulation: They possess very high dielectric strength and volume resistivity, making them ideal for electrical
    and electronic applications to prevent short circuits, current leakage, and arcing.

  • Outstanding Thermal Stability: Alumina ceramics can withstand continuous operating temperatures up to 1700°C (3092°F) and
    exhibit exceptional resistance to thermal shock, maintaining their structural integrity under rapid temperature changes.

  • High Corrosion & Chemical Resistance: They are inert and highly resistant to corrosion from acids, alkalis, and solvents, outperforming
    even the most resistant metal alloys like Hastelloy or titanium.

  • Exceptional Hardness & Wear Resistance: With a hardness second only to diamonds and carbides, they offer superior resistance to
    abrasion and wear, resulting in a long service life.

  • High Compressive Strength: They can withstand significant crushing loads, though they are brittle and have low tensile strength compared
    to metals.

  • Non-Magnetic and Radiolucent: Being non-magnetic, they do not interfere with sensitive equipment like MRI machines. Their radiolucency
    makes them invisible on X-rays, which is valuable in certain medical and research applications.

Applications of Alumina Ceramic part:

  • Semiconductor Manufacturing: Used in wafer processing, CVD, and etching equipment.

  • Vacuum & High-Temperature Furnaces: Ideal for insulating and assembling hot zones.

  • Medical Devices: Used in MRI equipment, X-ray systems, and surgical tools.

  • Chemical Processing: For pumps, valves, and reactors handling corrosive chemicals.

  • Aerospace & Defense: In sensors, insulators, and other critical components.

Customization and Quality Assurance

  • Customization: Many manufacturers offer alumina plates tailored to specific dimensions, shapes, and performance requirements
    based on customer drawings or samples.

  • Quality Control: Manufacturers adhere to strict quality control processes, including ISO certifications, to ensure the plates meet
    high standards of durability and performance
