<p>[Problem] In a joint with a contact material wherein a support material and a phosphor bronze brazing filler are melted and adhered, when the joint is heated, because the phosphor bronze brazing filler has already been melted when melted and adhered to the contact material, the fundamental self-flux function thereof has been reduced, and faults are generated in the joint section, and therefore when the contact is subjected to electrical opening and closing, the faults can cause peeling or wearing. [Solution] An electrical contact material using two kinds of phosphor bronze brazing filler having different melting start-times, with one of the phosphor bronze brazing fillers being melted to the contact material, and the other phosphor bronze brazing filler being bonded in an un-melted state.</p> |
