Silver coated copper powders are used wherever high conductivity (electrical and thermal) is needed.
In many cases silver coated copper powders can substitute pure silver powders and can help to save costs. Principally there are two types of silver coated copper powders:

a) Silver coated electrolytic copper powders

Suitable especially for 3-dimensional conductivity e.g. for use in carbon brush bodies or as tamping grades, for conductive plastics or elastomers as fillers, conductive adhesives, conductive pastes ...

b) Silver coated flaky copper powders

Suitable especially for 2-dimensional conductivity e.g. for use in conductive inks, screen printing, plane use of conductive adhesives and pastes, EMI-shielding, ...
