Question string sound/timbre as a function of string composition (steel, nickel, cobalt...)

Hello all,

I am an engineering professor and I am teaching a freshman lab class in which we learn some physics through electric guitars. Please see the following link for a description

EN1102 - Bailey Group

I have been trying to understand what the string metallurgy might have to do with the timbre of the strings. If I understand correctly, "bright-"sounding strings have higher power at higher harmonics than do "warm-"sounding strings. Is that accurate and/or relevant?

The "pure nickel" strings (surely nickel-coated steel) are said to be less "bright," rather "warmer" than steel. Does this mean that the higher harmonics are damped more heavily in the Ni? Does anybody know why that would be? I can imagine a few mechanisms; the most likely would seem to be magnetostriction, but somebody must have put this to the test.

I would appreciate it if anybody knowledgable or interested could respond; if it's a trade secret, please contact me directly...

Thanks.
Bill
 
Welcome to the forum, Bill!

I'm sure one of the EBMM engineers will reply to you if they have time. I'll send them a 'heads up'.
I've replied by private message too.
