Technical specifications
The brand alljy 1.3912 refers to the nickel group of precision alloys that are resistant to corrosion, subgroup of dispersion-hardening alloys. The composition of the two main metals — nickel and iron with additives of manganese, silicon, aluminum, vanadium, molybdenum. The share of nickel is 35−37%, Doping helps products to withstand the influence of aggressive media. The alloy has a low value of thermal expansion (in the range 20 — 400 ° C) and good thermal conductivity
