My vote is for brass or "copper alloy."

https://en.wikipedia.org/wiki/Brass

Note Wikipedia's "In contrast, bronze is an alloy of copper and tin.[2] Both bronze and brass may include small proportions of a range of other elements including arsenic, lead, phosphorus, aluminium, manganese, and silicon. The distinction is largely historical.[3] Modern practice in museums and archaeology increasingly avoids both terms for historical objects in favour of the all-embracing "copper alloy"."[4]

Since there is no way to scale them for size, if I opened a box and seen that color, I'd have said gold plated right away.
 
I've seen waveguide castings both in brass and gold plated brass. It depends upon the application.

Exactly as he said.

The color is so close too, that testing is necessary, at least for my eyes.
 
Even if it is gold plated, the surface is so small compared to the weight that I think the brass would be more valuable than the gold.

Not in military or enterprise telecoms applications Goran. It's obscenely thick. Normal stuff I'd agree with but not with those applications.
