Henry Repeating Arms claims their brass alloy used in the New Original Henry has the same tensile strength as steel.
Sorry for the late ( by many moons) reply...
I did in fact investigate the alloy used by the Henry Repeating Arms Co, and I can verify that it is
a very fine quality Gun Bronze with tensile strength ( and other delightful properties) equal to or exceeding that of
commonly used gun steels.! It will stand up to any loads that a steel toggle link can handle.
Unlike our Italian replicas, which only use common red brass :-(
