Abstract
The presently disclosed subject matter relates to multi-material electrical contacts, and methods of making multi-material electrical contact comprising a functionally graded monolithic structure, having a first metal and a second metal, an amount of the second metal as compared to an amount of the first metal increases with distance in the structure from a first surface to a second opposing surface of the structure such that the second metal content increases continuously or incrementally throughout the height of the electrical contact.
