- Carbon & Graphite Specialties
Graphite is highly functional with properties that include thermal resistance, electrical conductivity, anti-corrosion and lubricating property. It also possesses a wide variety of properties including ease of precision machine processing and lightness.
At SEC CARBON, we utilize these properties to the fullest by processing and manufacturing the graphite by itself, or as a composite material that can be used with resin or metals, into "shapes" desired by the customer.
The various products made in this manner are used in a wide range of fields from key industries to cutting edge fields. Our graphite products have received high acclaim as being necessary product for supporting the increasing sophistication of industry.
