I cannot attest to what Martin use in the past, it is beyond my personal knowledge.
I do have round lengths of stainless, brass, copper, nickel silver and cupro-nickel for manufacturing keys on flutes / clarinets and other musical instruments.
Nickel Silver has copper, nickel and zinc, Cupro Nickel has copper, nickel, iron and manganese.
I would be genuinely surprised if martin used cupro nickel, but again beyond my personal knowledge
