wwwwww..ssppeecciiaallmmeettaallss..ccoomm NIMONIC® alloy 105 (W. Nr. 2.4634) is a wrought CCoommppoossiittiioonn,, %% nickel-cobalt-chromium-base alloy strengthened by additions of molybdenum, aluminum and titanium. It has been developed for service up to 950°C, and com- The composition stated in BS HR 3 is as follows: bines the high strength of the age-hardening nickel-base alloys with good creep resistance.
