AMS 5666 | Nickel Alloy, Corrosion and Heat-Resistant, Bars, Forgings, Extrusions, and Rings | Annealed

What AMS 5666 covers

AMS 5666 is the aerospace material specification for nickel alloy, corrosion and heat-resistant, bars, forgings, extrusions, and rings.

AMS 5666 applies to nickel alloy 625, as nickel alloy, corrosion and heat-resistant, bars, forgings, extrusions, and rings, in the annealed condition.

Titanium Industries stocks Nickel Alloy 625 Round Bar to AMS 5666.

Nickel Alloy Inconel® 625 is used for aircraft turbines and other applications, chemical processing, heat exchangers and surface condensers, expansion joints and marine components.

Specifications that cross-reference AMS 5666 include AMS 2261, ASTM B446 and ASME SB446.
