Nickel 903
GTAW Solid Bare Welding Wire, Iron Base — Nickel 903
Nickel 903
Nickel 903 is a low expansion, high temperature, high strength nickel-cobalt-iron filler metal used to produce high quality welds in matching base metals. Large amounts have been used for space shuttle rockets and similar vessels.
Applications:
Stringer beads with controlled low heat input and ultra clean weldment conditions are essential for sound welds.
