Techalloy 413
Description
Techalloy 413 is used for TIG, MIG and oxy-fuel welding of70/30,
80120 and 90/10 copper-nickel alloys. This filler metal can beused
for MIG overlay on steel after a first layer with Nickel 208Filler
Metal 61). Dissimilar welding applications include joiningcopper-
ickel alloys to Nickel 200 or nickel-copper alloys.
