CMW® ELKONITE 4050 tungsten, high silver (discontinued **)
Categories:	Metal; Nonferrous Metal; Precious Metal; Silver Alloy; Refractory Metal; Tungsten Alloy
Material Notes:	This material has been rebranded as a part of the NAECO® ELKON® product line. ELKONITE® 4050 is a high silver material that uses a special tungsten powder. It is made by the press-sinter-infiltrate method. It was developed especially for use as a combination current carrying and arcing contact for molded case circuit breakers. Its strong structure improves its arc erosion resistance while maintaining good temperature rise and current interruption characteristics. ELKONITE® 4050 has approximately the same silver content as ELKONITE® 50S, but has higher mechanical properties due to its higher sintered strength. It is used in the higher rated household breakers.
