Tensile strength values for Steel Music wire are based on 0.4mm wire
The tensile strength values given for red gold alloys are based on data published in Aurum by the Interrnational Gold Corporation quoted from Mark Grimwade, Introduction to Precious Metals, Newnes Technical Books, Butterworth & Co., Kent, (1985). These values would appear to be exceptionally high, other sources tend to give maximum tensile strength values for red gold of somewhere in the order of 550 MPa with much lower yield strength values. The above values will represent an absolute maximum for gold alloys.
