Silver
Cadmium Oxide
Vaculoy SC85 and SC90 are silver cadmium oxide
composites with a fine homogeneous distribution of the cadmium oxide
particles within the matrix of silver. They have good electrical
conductivity, low contact resistance and are resitant to mechanical
wear and welding-in.
Silver cadmium oxide is widely used in contractors
where it's properties show an improvement over silver faced contacts.
Silver
Nickel
Vaculoy SN70 is a composite of silver and nickel
- it has a higher electrical conductivity than the silver tungsten
grades but does not have as good a resitance to mechanical wear
and arc erosion. The principle applications are main contacts and
air-break switchgear, contactor contacts especially in d.c. circuits
and medium to heavy duty relays.
