OD30mm Length100mm High Mechanical Strength Microcrystal Machinable Glass Ceramic Macor Rod
VR
Product Description
Machinable microcrystalline glass ceramics are fluorophlogopite microcrystalline glass with synthetic mica as the main crystalline phase, the main components are fluorophlogopite (Mg3K [AlF2O (SiO3) 3]) and glass composition with silica.
*Machinability applications: insulation pads, heat insulation pads, insulation supports, heat-resistant supports on various
mechanical equipment
*Application of insulation performance: key parts of lightning rod
*Application of thermal shock resistance: welding fixture, optical glass secondary molding mold, etc.
*Application of corrosion resistance: crude rod desalination electrode introduction rod, hanging
*Application of Electromagnetic Performance: Coil Skeleton of Missile Gyroscope
*Other performance applications: rotary vacuum pump rotor
