NILO® CF42


NILO® CF42

NILO® CF42 is used for the gas-metal-arc, gas-tungsten-arc, and submerged-arc welding of INVAR® alloy 42. NILO® Filler Metal CF42 is formulated to have low thermal expansion characteristics similar to INVAR® alloy 42, while providing freedom from solidification and reheat cracking. Argon is recommended for the GMAW-SPray process, Argon/25% helium for the GMAW-Pulsed Arc and Short-Arc processes, and INCOFLUX® 6 for the SAW process.
