CARBON GRAPHITE PRODUCTS |
|
|
For mechanical application
distinguishes three main groups of grades identified be
the two initial letters of the grade denomination:
FH
carbon/graphite
FE electographite
FF resin bonded carbon
The following two numbers identify the different grades
within the main material groups.
Example: FH42, FE45, FF51 |
 |
The following third
numbers indicate special manufacturing procedures:
• pressing partially pressing to size (only
with FH and FF grades)
• is static pressing (only with FH and FE grades)
Example: FH421, FE679, FF511
Supplementary treatments and impregnations with
metals, artificial resins and special salts are
indicated by the following letters and letter number
combinations added to the grade denomination: |
 |
-A antimony
-B lead-antimony
-C copper
-Z2, Z5 phenolic resin, cured
-ZH2, ZH5 phenolic resin, specially cured for
working temperatures up to 260C
-ZP2, ZP5 polyester resin, cured
-S redensified with carbon
-Y2, Y3, Y5 redensified with carbon |
 |
-Q for FE grades:
treatment to improve oxidation stability
-M slat impregnation to improve dry running capacity
-Examples: FH82A, FH42B, FH44C, FH42Z2/Z5,
FH82ZH2/ZH5, FH42ZP2/ZP5, FE45S, FH42Y3,
FE67Q, FE67M.
-Differences between Z2, ZH2, ZP2 and Z5,ZH5,ZP5
-Z2, ZH2, porosity
-zp2 ? 4 vol. %
-Z5, ZH5, gas density inspection of the finished
part or porosity ?1.5 vol.-% |
