Rondelles sur mesure en céramique

Corrosion Resistance: Provides excellent protection against rust, oxidation, and environmental degradation, making them suitable for use in harsh or corrosive environments.

Chemical Inertness: It is resistant to most acids, alkalis, and other corrosive substances, ensuring durability in harsh chemical environments.

Density: The density of 99.5% Alumina is approximately **3.90–3.95 g/cm³**, giving it a robust and dense structure.

Temperature Stability: Alumina conducts heat effectively compared to other ceramics, though it is lower than metals. Alumina withstands extreme temperatures, with a melting point of approximately 2,050°C.

Optical Transparency: Thin sections of high-purity alumina can be optically transparent, which is useful in specific optical and laser applications.

Electrical Insulation: It is an excellent electrical insulator, even at elevated temperatures.

Biocompatibility: Alumina is biologically inert and safe for medical applications such as implants and prosthetics.

Durability: Alumina is one of the hardest ceramic materials, making it highly wear-resistant and suitable for abrasive environments.

Low Dielectric Loss: It has a low dielectric loss, making it suitable for high-frequency electrical applications.

High Dielectric Strength: Provides excellent dielectric strength, supporting applications requiring insulating properties under high voltages.

Strength: It offers high compressive strength and good flexural strength.

Low Thermal Expansion: Alumina has relatively low thermal expansion, contributing to dimensional stability under temperature variations.
