Nimonic 105 Strip

A precipitation-hardenable nickel-cobaltchromium alloy with an addition of molybdenum for solid-solution strengthening. The relatively high aluminum content enhances both strength (through greater precipitation hardening) and oxidation resistance. The alloy has high creep-rupture properties at temperatures to about 1740°F (950°C). Used in gas turbines for blades, discs and shafts.STANDARD PRODUCT FORMSRound and extruded section.MAJOR SPECIFICATIONSBS HR3, Werkstoff Nr. 2.4634, AECMA Pr EN2179 – 2181LIMITING CHEMICAL COMPOSITION, %Ni .......RemainderCo .....18.0 – 22.0Cr ......14.0 – 15.7Mo .........4.5 – 5.5Ti ...........0.9 – 1.5Al ...........4.5 – 4.9C ..........0.12 max.Si ...........1.0 max.Cu..........0.2 max.Fe ..........1.0 max.Mn .........1.0 max.S .......0.010 max.B ...0.003 – 0.010Zr .........0.15 max.PHYSICAL CONSTANTS AND THERMAL PROPERTIESDensity, Ib/in3........................................................................0.289g/cm3.........................................................................8.01Melting Range, °F...................................................2350 –2450°C ...................................................1290– 1345Specific Heat, Btu/lb • °F....................................................0.100J/kg • °C...........................................................419Permeability at 200 Oersted (15.9 kA/m).................1.0007Coefficient of Expansion, 68 – 212°F, 10-6in/in • °F........6.820 – 100°C, µm/m • °C .........12.2Thermal Conductivity, Btu • in/ft2 • h • °F........................75.51W/m • °C ........................................10.89Electrical Resistivity, ohm • circ mil/ft...............................788µ Ω• m................................................1.31TYPICAL MECHANICAL PROPERTIES
