radiometaln.¹

Brit.

/ˈreɪdɪəʊˌmɛtl/, U.S.

/ˈreɪdioʊˌmɛdl/

Origin: Formed within English, by compounding. Etymons: radio- comb. form³, metal n.

Etymology: < radio- comb. form³ + metal n. The alloys were apparently so named on account of their frequent use in transformer cores for radios.

Electrical Engineering.

Also with capital initial. Any of a group of alloys consisting largely of nickel and iron (typically between 35 and 48 per cent nickel), noted for their high magnetic permeability.
