Thank you for the cupronickel suggestions. I'm going to order some CuNi brake line fittings and cut them up.
I also came across Molybdenum Gold cutting wire (aka EDM wire).
I will also try Hematite.
For aesthetic and artistic purposes, I'm trying to mix clay with small bits of metal and then cook it at ~1200.c, and then wet sand it to reveal the lustrous metal aggregate.
I have successfully done this with stainless steel, titanium (below) and molybdenum. It looks great. But I want to find...
Please recommend an Alloy or Element with the following properties:
Looks like gold (lusterous and yellow/brown)
Has a melting point above 1100.c
Doesn’t corrode easily
Is non toxic
Mohs greater than 4.0
Is fairly common/cheap
