Tungsten
Alloys and it's applications:
W Cu
Alloy
Tungsten/Copper is a powder metallurgical material produced
by the means of infiltration with copper contents from 10 to 40 %
typically 75%Tungsten 25% Copper, materials are back-cast with copper and
can be joined by welding or brazing with various supporting materials.
Advantages of
WCu:
- high arc resistance combined with good electrical conductivity
- high thermal conductivity
- low thermal expansion
- back-castable with Cu
Typical areas of application:
- arcing contacts in high and medium voltage
breakers for transmission and distribution of electrical power
- carrier plates or heat sinks as passive cooling elements of
electronic devices
- erosion electrodes for EDM made of Sparkal
- electrodes for other applications (surge protection, welding, laser
applications)
Tungsten Heavy Alloys
Tungsten alloys are materials with a high tungsten content and low
amounts of NiFe (binder material). They show similar high densities
as pure tungsten, but they are much easier to machine. Tungsten Heavy
Alloys are characterised in particular by their excellent strength
and ductility.
Tungsten Heavy Alloy 90%W + Ni + Cu
This product is a general purpose high
density tungsten-nickel-copper material. It provides the optimum
combination of properties in this range of materials.
