Extruded, fired and further processed through grinding and tumbling to meet your demanding tolerances. Thermalox® 995 yields components of outstanding quality, and we have other specialty beryllia formulations available for unique applications. Beryllia ceramics convey an exceptional combination of properties: Second only to Diamond among electrical insulating materials, Thermalox 995 provides thermal conductivity dissipating 285 W/m•K at room temperature. Low Dielectric Constant (6.76) and low tanδ dielectric loss tangent (.0004 at 1 MHz), permitting improved circuit performance at high frequencies. A Coefficient of Thermal Expansion (CTE) of 9 ppm intermediate to silicon or gallium arsenide and metals. Ten times greater thermal conductivity than alumina ceramics. At Materion Ceramics, we offer extruded rods and resistor cores in standard or customized diameters and lengths. Standard As-Fired Diameters Include: ø0.054" ø0.078" ø0.132" ø0.217" ø0.270" We also specialize in complex helix support rods with customized configurations.
