This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing. These extrusions have been used typically for parts requiring moderate strength and where distortion during machining must be minimized, but usage is not limited to such applications.
Rationale: AMS4173H results from a Five-Year Review and update of this specification. This standard is being reviewed as part of the SAE Five-Year Review policy. The committee will look at possible changes to ordering information and other potential updates throughout the standard.
