Metal Fabrication Requests

Every machining shop has its choice material. At Semco, that material is carbon graphite. We know the ins and outs of this material and can talk all day about isostatic vs. extruded graphite, or about graphite’s conductive and heat-resistant properties. While we are experts at graphite machining, we generally do not machine metal. Nevertheless, Semco Carbon occasionally receives metal fabrication RRF’s, projects we are not equipped to produce in house. Conversely (if you are a metal machining shop), your facility might receive graphite or carbon RFQ’s, projects that you are not equipped to produce. We would like to start a...

What is Graphite?

We’ve written a lot in this blog about our primary material, graphite. We want to clarify that when we talk about graphite in most industrial applications, we are discussing synthetic graphite. Synthetic graphite is the crystalline form of carbon. It is a man-made material that is extremely resistant to high temperatures and acidic or basic solutions. Graphite can be engineered to obtain specific properties such as density, electrical resistance, hardness, porosity, compressive strength, flexural strength, coefficient of thermal expansion, and thermal conductivity. Below, we will detail the processes that go into making synthetic graphite and the different forms it can...

Graphite Oxidation

As we have explained in this blog before, synthetic graphite (man-made graphite) is produced in hundreds of different graphite grades. Most of these graphite grades have been developed for specific applications, and each grade has its own set of properties associated with it. At Semco, we make it our business to be experts on synthetic graphite and the myrian properties of different graphite grades. We pass this expertise onto our clients so that they can choose the appropriate material for their application. With their extensive knowledge of these synthetic materials, our engineers can help clients solve very complicated issues, as...

Graphite Market Growth After COVID

The news is not a place to look for good news, at least not over the last month. Under the nightmarish headlines about what the virus is doing to people and communities are other frightening headlines about what it’s doing to the economy. In the current environment, with businesses idled and unemployment on a steep trajectory, it is hard to imagine growth in industrial output in anyone’s economic outlook for the short to mid-term. We at Semco, like all other businesses small and large, have watched with concern as events have unfolded. Would this downturn affect the market for graphite...

Semco is an Essential Business

Semco would like to share an important status update with our clients: through the current crisis, our graphite production operation will remain open. With the COVID pandemic pushing federal and local governments to institute various closures and social distancing measures, we wanted to reassure our customers that Semco will continue producing graphite products that they rely on. With close to 50 years of graphite production experience, Semco machines many parts and components that are used in essential products and processes across various industries. To get our clients the graphite components they need to run their important businesses, our company has...
