2 Nomenclature of material grades Our carbon and graphite materials are processed under strictly defined manufacturing processes using specified raw or treated materials. For more information on the manufacture, design and application of these materials, follow the QR-Code located on the back of this brochure, or visit Schunk offers three different groups of carbon materials for mechanical applications. These groups are identified by the two initial letters of the grade code: FH... FE... FF... resin bonded carbon The two figures following these initial letters identify the different grades within the material groups. Examples: FH42, FE45, FF52 A third figure indicates special molding processes:...1 pressing to size or partially pressing to size...9 isostatic pressing (only applies to FH and FE grades) Examples: FH421, FE679, FF521 Additional processing steps such as impregnations with metals, resins or special salts are indicated by a final letter or letter/figure combination: Examples: FH82A, FH44C, FH42Z2/Z5, FH82ZH2/ZH5, FH42ZP2/ZP5, FE45S, FH42Y2, FE679Q, FE679PS Z2, ZH2, ZP2: low residual porosity Z5, ZH5, ZP5: dense, gas leakage test on demand The following table shows the physical data of a selection of Schunk materials for mechanical applications. For special applications a multitude of other materials are available. One of these materials is SiC30. This unique silicon carbide / graphite composite material is problem solver or even already standard in various critical applications, where it is able to substitude carbon and silicon carbide materials. A C antimony impregnation copper impregnation Z2, Z5 impregnation with phenolic resin ZH2, ZH5 ZP2, ZP5 impregnation with phenolic resin for applications up to 260 C impregnation with polyester resin (Schunk patents DE , EP ) S, Y2, Y3, Y5 redensification with carbon Q, PS, M inorganic salt impregnation 02
