Monel 401
Description:
Monel 401 (UNS N04401 / W.Nr. 2.0842) is used primarily in specialized electrical and electronic applications. Monel 401 is readily autogenously welded by the gas-tungsten-arc process. Resistance welding is a very satisfactory method for joining the material. It also exhibits good brazing characteristics.
Features
Monel 404 has low magnetic permeability and low Curie temperature. Because its low magnetic permeability is not significantly affected by processing and fabrication, it is particularly suitable for electronic parts.
Applications
l Electronic and electrical devices
l Marine fixtures
l Chemical processing equipment
l Gasoline tanks
l Boiler feed water heaters
l Heat exchangers
