Product Description

Alumina Ceramic Gasket 95 Alumina Ceramic Washer Electrical Insulation Hexagonal 

Tired of fasteners failing under high temperatures, corrosion, or electrical interference?

Our Alumina Ceramic Gasket 95 Alumina Ceramic Washer are engineered to thrive in the harshest industrial conditions—

delivering unmatched durability and performance where metal fasteners fall short.

Core Advantages of Alumina Ceramic Fasteners

Extreme Temperature Resistance: Withstands continuous operation up to 1600°C (3000°F), far exceeding metal fasteners. Ideal for high-temperature furnaces, aerospace components, and industrial heating systems.

Superior Corrosion Resistance: Impervious to acids, alkalis, salts, and harsh chemicals. No rust, oxidation, or degradation—perfect for chemical processing, marine, and offshore applications.

Excellent Electrical Insulation: Volume resistivity >10¹⁴ Ω·cm, preventing electrical short circuits. Suitable for high-voltage equipment, semiconductor manufacturing, and electronic devices.

Lightweight & High Strength: 60% lighter than steel with comparable tensile strength (up to 350 MPa). Reduces overall weight of equipment without compromising structural integrity.

Wear & Abrasion Resistant: Hardness up to HRA 88, minimizing wear and extending service life in high-friction environments.
