Introduction to Alumina Plate
Alumina plate is a ceramic material made of high-purity aluminum oxide (Al2O3) through a high-temperature sintering process. It has a wide range of applications in many industrial fields with its excellent physical and chemical properties. As a non-metallic material, alumina plate has not only good mechanical strength and hardness but also excellent corrosion resistance and high-temperature resistance, making it an indispensable material for many industries such as electronics, chemical industry, aerospace, etc.
Alumina Plate
Characteristics of Alumina Plate
High strength and hardness: The hardness of the alumina plate is second only to diamond, which makes it particularly good in the face of wear and impact.
Excellent heat resistance: It can withstand high temperatures up to 1750°C and is suitable for environments that require high-temperature resistance.
Chemical stability: It has extremely high resistance to most acid and alkali solutions and is not easily corroded.
Electrical insulation: It has good electrical insulation properties and is suitable for use as an insulating material in electronic equipment.
Biocompatibility: Because it is non-toxic and does not cause allergic reactions, it is also used in the medical field.

Frequently Asked Questions (FAQs)
Can alumina sheets be processed into complex shapes?
Yes, although alumina sheets are difficult to process, complex shapes can be designed through precision machining techniques such as laser cutting and water jet cutting.
What is the price of alumina sheets?
The price of alumina sheets varies depending on factors such as material purity, size and processing complexity. Generally, products with high purity and special specifications are more expensive.
Can alumina sheets be used for food contact?
Yes. Alumina sheets are non-toxic and harmless, meet food safety standards, and are suitable for the production of food processing equipment.
Will alumina sheets deform at high temperatures?
Within the normal operating temperature range, alumina sheets are very stable and will not deform significantly. However, under extremely high-temperature conditions, slight expansion or contraction may occur.
What should be paid attention to in the maintenance of anodized aluminum plates?
Avoid collision with sharp objects to cause scratches or damage in daily use. For surface stains, wipe gently with a soft cloth dipped in a mild detergent, then rinse with clean water and dry.
