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
