Description

MONEL® nickel-copper alloy **1 (UNS N****1) is used primarily in specialized electrical and electronic applications. The composition of MONEL alloy **1 is shown in Table 1. Some typical constants and properties are given in Table 2. Alloy **1 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 **1 is normally furnished as wire; other forms may be obtained on request. Inquire for complete information.
