Typical Applications
Properties
Electrographite  
On large commutator machines with high electrical, thermal and mechanical demands on brushes Good electrical and thermal conductivity as well as good sliding properties. By varying the raw material and the manufacturing process it is possible to achieve certain combinations of properties

RE 28
RE 50

RE 59
RE 60

RE 75
RE 76
RE 80
RE 92
RE 98
E 33

E 34
RE 95
  
Metal Graphite  
On machines with high electrical load on the brushes and no or small commutating demands, like sliprings and low voltage machines; Silver grades are mainly used on tacho generators or for measuring purposes A combination of the good sliding ability of the graphite and the high conductivity of the metal is achieved and, depending on the graphite content, the one or the other is more dominant

RC 67
RC 73
RC 87
RC 90
RC 95

RS 70
  
Resin Bonded Graphite  
On three phase AC commutator motors and on small DC machines Good commutation but limited ability to carry load

RX 88
RX 91
  
Hard Carbon  
On small machines with undercut mica between segments and on small thyristor fed DC machines Good polishing ability, good commutation, but the ability to carry electrical load is less than that of brushes made from electrographite
