Below is a list of Graphite Plates manufacturers from Denver, Pennsylvania. Graphite plates are typically smooth, flat and have uniform thickness. Manufactured through the process of extrusion, they are electrically and thermally conductive and therefore are used in many industrial applications. Graphite is also a chemically inert substance and has an extreme temperature resistance. Because of these unique properties, graphite outperforms almost every other material, including steel and titanium, in plate applications that require very high temperatures.
