描述：The 7156200 is a 100mm Macor? machinable glass Ceramic Bar can be machined into complicated shapes and precision parts with ordinary metalworking tools, avoiding the need for expensive diamond tooling. Its coefficient of thermal expansion readily matches most metals and sealing glasses. With a maximum operating temperature of 1000°C and a maximum continuous operating temperature of 800°C. It is ideal for high temperature applications. It is non-wetting, exhibits zero porosity and unlike ductile material will not deform. Machining tolerances are surprisingly tight, (up to 0.013mm) and it can be machined to a surface finish of less than 0.5μm and polished to a smoothness of 0.013μm. Configurations are limited only by the available equipment and the experience of the machinist. Macor? can be joined or sealed, both to itself and to other materials, in a number of different ways, metallised parts may be soldered, epoxy provides a strong joint and sealing glass creates a vacuum tight seal. . Machinable with ordinary metalworking tools . Allows fast turnaround, no post-firing required . Holds tight tolerances . No outgassing and zero porosity
