Graphite Materials and Thermal Processing

Fall evenings and apple cider, baseball and hot dogs, graphite materials and thermal processing -- these things just go together. Thermal processing and vacuum heat treating shops commonly use fixtures made of graphite materials on which to set parts to be treated. These graphite fixtures have excellent thermal stability, allowing them to be used again and again through multiple heat treat cycles (think of the durability of a graphite heating element). In addition to that stability, graphite materials offer significant cost advantages when compared to other materials used to make fixtures to be used in thermal processing, like high nickel/chromium...

Graphite Fabrication and Metal Casting Molds

Graphite Fabrication and Metal Casting Molds Graphite serves useful functions in various industries and in the production of other materials. We’ve written extensively here about carbon lubricant for industrial machining, and graphite molds used to make things as various as gold ingots and zinc-aluminum alloy components. Metal casting molds, of course, are quite often made of graphite. Some of the graphite fabrication that we do at Semco is machining metal casting molds or graphite molds to shape other materials. Graphite has the lucky and quite unique quality of not sticking easily to many other materials. That quality, along with its...
