Machinable Ceramics material

Machinable Ceramics is a polycrystalline composite made of fluorophlogopite and glass. It possesses good machinability and can be lathed, milled, planed, ground, bored, incised and threaded. It also has the advantages of insulation, pore-free, high/low-temperature resistant, acid and alkali resistant and thermal impact resistant.

Main properties
Magnetic susceptibility 1.2×10-6 Dielectric constant 6~7
Breakdown voltage ≥15 kV/mm Flexural strength ≥108MPa
Fracture Modulus 15000bf/in2 Impact toughness ≥ 3.8 kJ/m2
Knoop hardness 1.76~3.43 kN/mm2 Volume density 2.5~2.8 g/cm3
Range of operating temperature -200~+1000℃ Thermal expansion coefficient ≤9.4×10-6 /℃
Thermal conductivity ≥ 1.7 W/m·K    

Applications:
    It is widely used for nuclear, microwave high vacuum insulation, high precision magnetism-free skeleton for aeronautic and astronautic electrical devices, ultra-high voltage insulation for electric motors and structural parts at strong erosion environments. In terms of machinability, it can take place of aluminum oxide and boron nitride ceramics that are difficult to machine.

Specifications:
    Rod:φ20mm~φ70mm, up to 150mm long.
    Plate: Square rod, plank specific size can telephone consultation.
