Material introduction
Machinable ceramics (Glass-ceramics) are versatile materials with high hardness, strength, and excellent modulus of elasticity that exhibit excellent mechanical properties, making them suitable for industrial applications with extreme forces and wear. It also offers high-temperature stability, low thermal conductivity, and good thermal shock stability, making it suitable for thermal insulation and heat-preservation applications. Additionally, its excellent electrical insulation properties make it highly effective in electronic and electrical applications.
Features:
Machinable ceramics are a very unique and useful material with several compelling properties.
1. Excellent mechanical properties and applications
Machinable ceramics have excellent mechanical properties, including high hardness, strength, and excellent compressive properties. These properties make machinable ceramics ideal for many industrial applications, particularly in environments where materials are subjected to extreme forces and wear.
1) High hardness and strength:
① Rockwell hardness: 40 for R45N.
② Vickers hardness (load 500g): 11.5GPa (1175 kg/mm²).
③ Modulus of elasticity: At 25℃, the modulus of elasticity is 65GPa.
2) Flexural strength: At 20°C, the flexural strength is 108MPa.
3) Compressive strength: At 20°C, the compressive strength is 488MPa.
These mechanical properties allow machinable ceramics to remain stable under impact and stress, reducing the likelihood of cracking. Due to their high strength and wear resistance, machinable ceramics are often used to manufacture a wide range of high-performance industrial components, such as parts in milling machines, sliding parts, and cutting tool blades.
2. Excellent thermal properties
Machinable ceramics also have excellent thermal properties, including high temperature stability, low coefficient of thermal expansion, and good thermal shock stability.
1) Maximum Use Temperature: 800℃.
2) Thermal Conductivity: At 25℃, the thermal conductivity is 1.71 W/(m·K).
3) Thermal Expansion Coefficient: 7.2 × 10⁻⁶/℃.
4) Thermal Shock Resistance: ΔT=200℃.
These properties make machinable ceramics useful in applications where thermal insulation or insulation is required. For example, in some chemical process equipment and high-temperature furnaces, machinable ceramics can be used as insulation to help control temperature and protect sensitive mechanical components from overheating damage.
3. Excellent electrical performance
Machinable ceramics also have excellent electrical insulation properties, making them valuable in electronics and electrical applications.
1) Electrical breakdown strength (dielectric strength): 30 KV/mm.
2) 20℃ Volume Resistivity: At 20℃, the volume resistance is 1016 Ω.cm.
These electrical properties make machinable ceramics highly effective in high-voltage and high-frequency applications, providing reliable insulation protection.
In conclusion, this machinable ceramic material excels in various demanding application environments, particularly in fields requiring high hardness, strength, and excellent thermal and electrical properties.
