ELKONITE 20S, 30S, 35S, 40S, 45S, 50S, 4050, and 2088 are tungsten-silver compositions with the tungsten content ranging from 50-88 wt.%. Tungsten has the highest strength and the highest melting temperature of the refractory metals. This is the principal factor in determining resistance of a contact to arc erosion and mechanical wear. The strength, erosion, and weld-resistance characteristics of the contact increase with increasing tungsten content; the electrical and thermal characteristics decrease. This datasheet provides information on composition and physical properties. Filing Code: W-22. Producer or source: CMW Inc.
