    Dear all,
    Recently while performing propeller blade analysis I came across material NiAlbronze with its code 626.,generally for propller NiAlbronze is used with UNS C95800 or UNS C95500.
    Does anybody knows where I will get the details on this code?
    Thanking you in advance.

    Most likely one of the old superceded copper numbers. Modern alloy number can be found by adding "00" to the end. So alloy 62600 is an aluminium bronze superceded in 1971.
    Fe 2.0-4.4, Al 9.7-10.7, Mn 1.5 max, Si 3.0-4.5, Cu remainder

    Or could to refer to a spec number, QQ-B-626 could be used for a propeller, but is leaded brass, not bronze.
