Copper based composite material reinforced with continuous tungsten fibres.
Code: IMC-P-00-0029-UMMS
Institute of Materials and Machine Mechanics
Description:
The technology of preparation depends on the required properties of composite material and includes the vacuum infiltration of tungsten fibres with molten copper or vacuum hot pressing of galvanic coated tungsten fibres.
Inovation:
The composite material exhibits substantial increase of high temperature strength while the excellent leading properties of copper remain unaffected. The main advanteges include low coefficient of thermal expansion, high electrical and thermal conductivity, high abrasion resistance, low burning of electric contacts.
Application:
Typical field of application is the production of electrodes or electric contacts of rotating components.
State:
The technology has been developed and tested. It is not further developed, it is ready for introduction into practice.
Cooperation:
Joint research and realization, sale of licence for production.
