Cobalite
® 601
 Description
Cobalite ® 601 is a pre-alloyed powder with a chemical composition of
10% Co / 20% Cu / 70% Fe. The mechanical properties are very similar
to those of Cobalt EFP. The low cobalt content ensures a cost effective
alternative to cobalt powders. The alloy benefits from a good oxidation
resistance, is relatively free flowing and exhibits ease of cold handling
and cold compaction.
Sintering
(Sintering Charts)
The pure powder is sintered in a standard hot press in a temperature
range of 750 - 850°C, although it can be sintered up to 950°C without
any significant changes in the microstructure. (SEM
Cobalite ® 601 microstructure) It should be noted that Cobalite
® 601 is usually sintered in combination with other elements (e.g. Fe,
W, WC and bronze) to optimise the bond’s mechanical and wear properties
for the application. (Sintering
charts with blends)
Typical
applications
Cobalite ® 601 is proving itself extremely universal, being used in
almost every application where cobalt based bond systems are being employed.
Wet and dry sawing and grinding of stone (granite and marble), concrete
and asphalt in sizes ranging from 230 mm to more than 2 meters in diameter
are typical applications.
