Tough Alloys is a Reliable Nimonic 105 Supplier in Mumbai, offering high-quality alloy products such as rods, bars, and sheets for critical applications in aerospace, turbines, and industrial sectors. Nimonic 105 alloy is a wrought nickel-cobalt-chromium (Ni-Co-Cr)-based alloy made further strong by additions of molybdenum, aluminium, and titanium. It has been developed for service up to 950 °C and combines the high strength of age-hardening with better creep resistance.
The production of Nimonic 105 begins with high-frequency melting in air, followed by air casting. For more critical applications, the alloy is produced using vacuum melting and electro-slag refining to ensure higher purity and performance. This process makes Nimonic 105 ideal for use in turbine blades, discs, forgings, ring sections, bolts, and fasteners, where high strength and reliability are required.
NIMONIC alloy 105 is manufactured through high-frequency melting in air, followed by air casting. For more demanding applications, the alloy is produced using vacuum melting and electro-slag refining to ensure enhanced purity and performance.
This precipitation-hardenable nickel-chromium-cobalt alloy includes molybdenum for solid-solution strengthening. Compared to similar alloys, NIMONIC 105 contains higher levels of aluminum and titanium, which improve its strength through precipitation hardening.These properties make NIMONIC 105 a preferred choice for high-performance and critical applications in aerospace, power generation, and industrial settings.
Applications of NIMONIC Alloy 105 include:
These heat treatments can be done for following purposes-
Turbine blades, discs, forgings and ring sections, all of which may be produced from as-extruded, as-forged or subsequently cold worked starting stock.
Bolts and fasteners for which extruded and cold worked bar or section is recommended as starting stock.
Welding techniques recommended for Nimonic 105 include gas-tungsten arc welding, gas metal-arc welding, submerged-arc welding and shielded metal-arc welding. Usage of a matching alloy filler metal is recommended for the welding process and if a matching filler is absent, an alloy rich in Ni, Co, Cr, Mo is can be used. During the absence of a matching filler metal.
Nimonic 105 can be heat treated in 4 four steps. The steps are as follows: Solution annealing for 4 h at 1149°C (2100°F) followed by air cooling. Heating for 16 h at 1056°C (1925°F) followed by air cooling. Heating for 16 h at 849°C (1560°F). Air cooling to reach precipitation-hardening.
