产品特点
1. High temperature resistance: Maintains strength without degradation at temperatures up to 1200℃, with short-term temperature resistance up to 1400℃.
2. Thermal shock resistance: Low thermal expansion coefficient (3.2×10⁻⁶/℃), able to withstand drastic temperature changes without cracking.
3. Abrasion resistance: High hardness and self-lubricating properties, resulting in a low coefficient of friction.
4. Chemical stability: Resistant to most acids and bases (except hydrofluoric acid and concentrated strong alkalis).
5. High mechanical strength: Compressive strength can reach over 2000 MPa, and flexural strength is 300-600 MPa.
