Graphite PartGraphite Part is formed for use in a wide variety of manufactured parts benefiting the automotive, aerospace, semiconductor, chemical, metallurgical, nuclear and electronics industries. It is usually the result of a copper and pure graphite composite, creating a material that is both structurally sound and reliable. Copper graphite is expensive, but it has improved conductivity and strength compared to pure graphite. Other metallic graphite mixtures may be used but may prove less effective.
