Alloy 105

Overview

Alloy 105, Nimonic® 105, W.Nr.2.4634, BS HR 3, GH4105
Note that Nimonic® 105 is a registered trade mark of Special Metals Corporation group of companies.

Overview

Alloy 105 is a wrought nickel-cobalt-chromium-base age hardening alloy strengthened by additions of molybdenum, aluminum and titanium. It has been developed for service up to 950°C, and combines the high strength of the age-hardening nickel-base alloys with good creep resistance.

Application

Alloy 105 is used for thermal turbine blades, materials for key high temperature components of ultra-supercritical thermal turbine, discs, aero-engine turbine blades, forgings, ring sections, bolts and fasteners, etc.
