This specification covers an aluminum alloy powder metallurgy product in the form of sheet 0.010 to 0.250 inch (0.25 to 6.35 mm) in nominal thickness.<p>This sheet has been used typically for parts requiring a combination of intermediate strength, high modulus, and thermal stability up to 750 degrees F (399 degrees C), but usage is not limited to such applications.
RATIONALE AMS4266B results from a limited scope ballot to stabilize this document. NOTICE AMS 4266B has been declared "STABILIZED" by AMS Committee D. This document will no longer be updated and may no longer represent standard industry practice. This document was stabilized because it contains mature technology that is not expected to change and thus no further revisions are anticipated. Previously this document was reaffirmed as non-current. The document was issued in March, 1994 and has never been technically updated. Users of this document should refer to the cognizant engineering organization for disposition of any issues with reports/certifications to this specification; including exceptions listed on the certification. NOTE: In many cases, the purchaser may represent a sub tier supplier and not the cognizant engineering organization.
