Machinable Glass Ceramics/ Ceramic Insulator/ Macor

الوصف

Machinable Glass Ceramic has a continuous use temperature of **0C and a peak temperature of ***0C. Its coefficient of thermal expansion readily matches most metals and sealing glasses. It processes 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× ***6 Dielectric constant 6~7 Breakdown voltage ? *5 KV/mm Flexural strength ? **8Mpa Fracture Modulus ****0bf/in2 Impact toughness ? 3.8 KJ/m2 Knoop Hardness **6~**3 kg/mm2 Volume density 2.5~2.8 g/cm3 Range of operating temperature ***0~****0C Thermal expansion coefficient ? *4× ***7 /K Thermal conductivity ? 1.7 */*@******************** 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: Dia*5mm~Dia**0mm, up to **0mm long Plate: Customized various sizes. Share
