Profile: Vacuum Impregnanted Products manufactures tungsten based electrical contact metals. We supply medium to high voltage switchgear contacts, resistance welding electrode materials, tungsten copper electrode materials for electro discharge & electro chemical machining and semi conductor heat-sink bases. The copper tungsten grades for contact metals are vaculoy CT60, CT70, CT75, CT78 and CT80. This range of compositions will cover most applications for arcing contacts in air blast, oil immersed and SF6 gas circuit breakers. The higher conductivity grade vaculoy CT60 is also for onload tapchanger contacts operating in oil.
