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
