Designer Extruded and Isostatic Graphite

Graphite is Lubricating, and… Graphite naturally has a unique set of physical properties that allows it to be used in environments where other materials would degrade or perform poorly. For instance, graphite can be used in conditions where traditional lubricants and other self-lubricating materials will fail. It can withstand high temperatures, corrosive media, and dry atmospheres, all while maintaining a low coefficient of friction and remaining dimensionally and thermally stable. But graphite as a lubricating material is typically not the first use of this wonder material that comes to mind. Most people, if thinking of graphite in an industrial setting,...

Machining Graphite Requires Knowledge and Care

Machining graphite can prove tricky, particularly when components with intricate geometries require outstanding accuracy. Here are four points to keep in mind when machining any graphite grades: 1. Choose the Correct Graphite Grade Graphite grades are difficult to distinguish visually, especially to the untrained eye. That being said, all graphite grades feature unique physical characteristics and properties that our graphite experts at Semco can easily recognize. Graphite grades are grouped by average particle size. The general rule is that 0.030’’ particle size materials are extruded materials, while materials in the 0.002’’ down to microns particle size are isomolded graphite grades....

Graphite and High Heat Applications

While we may be entering the coldest season of the year, it is always hot in places where many graphite applications live and work. Whether you are in need of sintering material, graphite heating elements, or other high temperature graphite applications, Semco Carbon has the technical knowledge and the machining capabilities to help solve your graphite machining project. High heat applications are sort of our calling card at Semco (no surprises there; graphite is a notoriously heat-tolerant material). Below are some of the product lines we can custom machine for you: Sintering Material Sintering trays are durable base components used...
