Properties of NeyOro® K

Neyoro® K is a markedly lower cost gold base alloy developed by DNI to counter the increasing costs of precious metals yet maintain the benefits of the traditional , higher gold content alloys. It is particularly well suited for uses where good wear resistance and low electrical noise is required, for example in slip ring and sliding contact applications.
