MODISON offers a complete range of Silver Cadmium Oxide Contacts in diverse forms manufactured by Internal Oxidation as well as Powder Metallurgy to meet customer’s specific requirement. These contact materials have high resistance to contact welding and arc erosion with low contact resistance.

MODURIT ZH : Produced by Internal Oxidation of sliver and cadmium alloy from one side. Under high temperature & pressure, oxygen diffuses and oxidizes the cadmium. CdO particles precipitate in silver matrix. CdO particles at the surface are very fine and the particle size increases gradually and is coarse towards the end. This material has excellent homogeneity without any depletion zone. CdO free backing AgCd layer (10 to 30% of the thickness) is available which has 100% bond with AgCdO top layer by use of special Internal Oxidation process.

MODISON started production of this material under Licence from DODUCO GmbH, Germany with whom we had technical collaboration from 1983 till 1996.
