Overview
As a leading supplier & manufacturer in China, AEETHER supply cost-effective Monel 401 Products.
MONEL® nickel-copper alloy 401 (UNS N04401) is used primarily in specialized electrical and electronic applications.
Alloy 401 is readily autogenously welded, in the thin sections in which it is most often used, by the gas-tungsten-arc process. Resistance welding is a very satisfactory method for joining the material. It also exhibits good brazing characteristics.
Alloy 401 is normally furnished as wire; other forms may be obtained on request. Inquire for complete information.
