Mechanical Applications

 

We supply carbon and graphite components to the automotive and household appliance industries, as well as to mechanical engineering companies. Our customers include not only manufacturers of compressors, vacuum and other pumps, sealing systems and sliding elements, but also processors of semifinished products and producers of injection moldings.

 



Carbon sliding materials have high self-lubricating qualities, and in addition, are excellent in thermal and chemical resistances. Such carbon materials have been used more widely as sliding material in many fields. Recently, they are used in paticular for anti-pollution purposes. Having started very early the development and manufacture of carbon materials in various many kinds, FMC is providing quality carbon products to meet the needs and demands from many different fields.

Features

  • Chemical stability : CARBON has such a nature that it is not easily attacked by ordinary solution of acids, alkalis, of organic solvents.Chemical resistance is described in more detail in item 4 "Chemical properties".

  • High thermal conductivity : Owing to CARBON's high thermal conductivity, heat generated at sliding part can be effectively dissipated. Thus, counterface material may not be damaged with minimized wear of CARBON .

  • High heat resistance : Heat can hardly degrade the machanical strength and chemical properties of CARBON . If ample oxygen exists, oxidation will be started at a temperature over 350°C or so. When no oxygen is supplied, however, CARBON will not be oxidized even at a higher temperature between 450°C and 500°C(dependant on grade).

  • High heat-shock resistance : Coefficient of thernal expansion is very low as compared with that of other metal materials. CARBON withstands a repetition of abrupt temperature change, incurring little crack. It should also be noted that CARBON impregnated with resin or metal has a somehow lower heat  heat-shock resistance.

  • Self-lubricating property : CARBON represents an outstanding self-lubrication, namely, it can be used without lubrication. Owing to this important nature, CARBON is very suitable for use where undersirable contamination by lubricant or similar accuracy to the case of ordinary metal materials.

  • Excellent machinability CARBON has an excellent machinability, and can be machined on machine tools such as lathes, drilling machines, milling machines, etc., obtaining the similar accuracy to the case of ordinary metal materials.

  • Others : One of the major advantages of carbons is its porosity. By ipregnating the carbons with a resin or the like in the pores, they can be made impervious. After such treatment, carbons may be used as sealing materials. Further with this treatment, mechanical strength such as compressive strength, bending strength, etc. of carbons can be increased also along with its improved wear resistance. It should be noted that consultation should be made with us for examination of your intended uses of CARBON under any applicable regulations.
