Filler metal for welding NILO® 36 / INVAR®.

NILO alloy K (UNS K94610/W. Nr. 1.3981), a nickel-iron-cobalt alloy containing approximately 29% nickel and 17% cobalt. Its thermal expansion characteristics match those of borosilicate glasses and alumina type ceramics. It is manufactured to a close chemistry range, yielding repeatable properties which make it eminently suitable for glass-to-metal seals in mass production applications, or where reliability is of paramount importance.

UNS N06075, Werkstoffnummer 2.4630 and 2.4951NIMONIC® alloy 75 is an 80/20 nickel-chromium alloy with controlled additions of titanium and carbon. First introduced in the 1940s for turbine blades in the prototype Whittle jet engines, it is now mostly used for sheet applications calling for oxidation and scaling resistance coupled with medium strength at high operating temperatures. It is still used in gas turbine engineering and also for industrial thermal processing, furnace components and heat-treatment equipment. It is readily fabricated and welded.

UNS N07080, W.Nr. 2.4631 and 2.4952NIMONIC® alloy 80A is a wrought, age-hardenable nickel-chromium alloy, strengthened by additions of titanium, aluminum and carbon, developed for service at temperatures up to 815°C (1500°F). It is produced by high-frequency melting and casting in air for forms to be extruded. Electroslag refined material is used for forms to be forged. Vacuum refined versions are also available. NIMONIC alloy 80A is currently used for gas turbine components (blades, rings and discs), bolts, nuclear boiler tube supports, die casting inserts and cores, and for automobile exhaust valves.

UNS N07090, W.Nr. 2.4632NIMONIC® alloy 90 is a wrought nickel-chromium-cobalt base alloy strengthened by additions of titanium and aluminum. It has been developed as an age-hardenable creepresisting alloy for service at temperatures up to 920°C (1688°F). The alloy is used for turbine blades, discs, forgings,ring sections and hot-working tools.

NIMONIC® alloy 901 (UNS N09901/W.Nr. 2.4662) is an age-hardenable Ni-Fe-Cr superalloy with significant additions of molybdenum, titanium and aluminum. The alloying route for this high performance material may include combinations of vacuum induction melting, vacuum arc remelting and electroslag remelting, according to the final application and the customer’s specification. Typically, the alloy is used for gas turbine engine discs, shafts, rings, casings and seals with a maximum service temperature of around 600°C (1100°F).
