MACOR® Machinable Glass Ceramic is a revolutionary material that combines the beneficial properties of ceramics with the convenience of easy fabrication. This unique material allows for precision machining using standard machine tools, eliminating the need for specialized equipment or expertise in ceramics. As a result, MACOR® opens up a world of possibilities for industries requiring high-performance ceramic components without the traditional complexities and costs associated with ceramic manufacturing.

The production of MACOR® involves melting and casting using conventional glass-making techniques. This fluorine-rich glass undergoes a controlled heat treatment process, resulting in the formation of fluorphlogopite mica crystals within an alumino-borosilicate glass matrix. The intricate structure, characterized by a 55% crystalline phase with uniformly distributed mica crystals, imparts MACOR® with its distinctive properties. This material resembles opal glass in appearance, adding an aesthetic dimension to its functional benefits.

MACOR® is renowned for its exceptional physical properties. It can withstand continuous use at temperatures up to 800°C, making it suitable for high-temperature applications. Its thermal expansion coefficient aligns well with most metals and sealing glasses, ensuring compatibility in various assemblies. Moreover, MACOR® is non-flammable, non-wetting, and exhibits zero porosity, maintaining structural integrity even under demanding conditions. As an excellent electrical and thermal insulator, it is ideal for applications requiring reliable insulation at high voltages and temperatures.

One of the standout features of MACOR® is its machinability. It allows for tight machining tolerances up to 10 microns and can achieve a surface finish of less than 0.5 micron. The material can be polished to an extraordinary smoothness, ensuring precision in critical applications. Conventional machining processes are applicable, and the only limitation is the equipment and expertise of the machinist. This versatility makes MACOR® a preferred choice for custom and complex component manufacturing.

In addition to its machinability, MACOR® offers versatile options for sealing, joining, and metallizing. It can be joined to itself or other materials through various methods, including soldering of metallized parts, brazing, and epoxy bonding. These techniques ensure strong joints and vacuum-tight seals, expanding its utility across different applications. Whether through mechanical joints or advanced metallization processes, MACOR® provides reliable solutions for intricate assemblies.
