Techalloy 418
A Lincoln Electric Company
Description
Techalloy 418 is used for TIG or MIG welding of copperalloys
(ASTM B127, B163, B164 and B165 UNS Number N04400). This
filler metal can be used for MIG overlay on steel after a firstlayer
with nickel 208( Filler Metal 61). Dissimilar weldingapplications
include joining Monel alloys to Nickel 200 and copper-nickelal
loys. This product is widely used in marine applicationsbecause
of its good resistance to the corrosive effects of seawaterand
brackish waters
