Graphite and Oxidation

A recurring issue we hear about from people using graphite components is graphite oxidation. This term describes unwanted redox reactions where oxidizing agents modify graphite properties negatively. Hence, especially at high temperatures, steps need to be taken to eliminate oxygen presence so that oxidation and deterioration of graphite components is avoided. Semco strives to educate our clients who order custom graphite components about the proper environments in which those components should operate. However, new clients will come to us expressing their frustration that graphite components are failing long before they should. One reason to work with the synthetic graphite experts...

Molded Graphite Rods

Graphite is well known for its corrosion resistance and good thermal conductivity. At Semco, we have noted an uptick in a particular mechanical application of synthetic, high density graphite: molded graphite rods. With this large increase in requests for molded graphite rods in various diameters, we have decided to add a new piece of equipment that would allow us to substantially increase the volume of rods produced. This dowel rod machine takes high density graphite blocks, which can be machined with more precision than with less dense material, and shapes them into rods that are useful across industries, in a...

Graphite Cement: A High Temperature-Resistant Building Material

Graphite cement typically refers to a material with adhesive and bonding physical properties that contains graphite as one of its primary components. This is not your typical cement, one of the most ubiquitous, and necessary, building materials used by people today. Your typical cement is made of forms of lime, silica, iron, and aluminum. Like manufactured graphite, cement’s formula can be adjusted to suit specific purposes. One of those materials that can be added to cement to give it certain properties is graphite. Graphite is a form of carbon known for its excellent electrical conductivity, lubricating properties, and high temperature...

The Carbon Material Par Excellence, Synthetic Graphite

Among carbon materials, synthetic graphite is one of the most fascinating and has found its place in a wide range of industries due to its unique properties. At Semco, we work with various forms of graphite, but synthetic graphite stands out as a highly valuable and versatile variant. With its exceptional electrical conductivity, thermal stability, and mechanical strength, synthetic graphite has become a game-changer in advanced industries. We’re taking a step back here from the details of machining graphite components in order to explore the remarkable properties and applications of this unique carbon material. We’ll also try to shed light...

EDM Graphite Machining

Some metal fabrication jobs, especially ones that cannot be done properly with a grinder or where milling graphite won’t work, are best done using EDM graphite machining, including wire EDM. In fact, graphite has become indispensable to the field of electrical discharge machining (EDM). At Semco Carbon, we have harnessed the full potential of EDM graphite machining to provide our clients with unparalleled precision and efficiency. In this post, we will delve into the world of EDM graphite machining and explore the numerous benefits it brings to the table, as well as the challenges posed by machining parts to be...
