1. High Hardness and Strength:Alumina sheets have a high hardness level, comparable to that of diamonds, which makes them highly resistant to wear and abrasion. Their excellent strength ensures durability even under harsh conditions. 2. Excellent Thermal Stability: With a high melting point and low thermal expansion, alumina sheets can withstand extreme temperatures, making them ideal for high-temperature applications. 3. Electrical Insulation:Alumina sheets is an excellent electrical insulator, which is crucial for applications requiring reliable insulation in electrical and electronic components. 4. Chemical Resistance:Alumina sheets are highly resistant to most acids and alkalis, as well as other corrosive substances, ensuring long-term performance in chemically aggressive environments. 5. Low Density: Despite their strength and durability, alumina sheets have a relatively low density, which is beneficial in applications where weight reduction is important.
