Product Definition & Uses
The high electrical and thermal conductivity of copper is combined with arc-resistant and non-welding properties of tungsten and molybdenum, or their carbides, to form extensive series of compositions, each designed to give the best performance for your particular application.
These materials are generally used as electrode materials for resistance welding and similar related applications and for such heavy duty contact applications, relays, switches, etc…
These materials excel in these applications because they will withstand the effects of the arcing to the interruption of large currents.
Typical applications include :
resistance welding electrodes
EDM electrodes
circuit breakers ( air and/or oil immersed )
arcing tips
make-and-break contacts
heavy-duty contactors
relays/switches
Superior Performance
AMPCO® refractory alloys are manufactured by the powder metallurgy techniques of pressing, sintering and infiltrating in a very high degree of uniformity, held In the fine-grained microstructure of the finished material. To the user this means an extremely high performance material which will stand up uniformly the most severe applications and outlast other brands.
AMPCO® copper-tungsten alloys are of the highest quality available and the physical properties of our alloys are considerably above those specified under RWMA standards.
