SEW 385 Grade Ni46 soft annealed (+A)
SEW 385 Grade Ni46 soft annealed (+A) introduction
The iron alloy with special thermal expansion Ni46, material number 1.3920, is used for compounds of metal and glass and for compounds of metal and ceramics, for expansion governors as well as for bimetals (according to DIN 1715). The break point temperature (temperature at which a break point in the expansion-temperature-curve occurs) is 400 degrees C. The cupping index at 1 mm thickness is 10.5 mm.
Equivalent material: DIN 1.3920, EN 1.3920
