What is the coiled metal wire on the actuator arm of a hard drive if it’s not copper?

I was taking apart some hard drives last night, first time, and the last one was different. All the rest were coiled copper on the actuator arm but this one was a white metal. Silver? Aluminum?
Sorry the picture is misleading, this was a previous hard drive but I circled the coil in case I’m using the wrong descriptors. I can get a picture later today but I’m out now and my curiosity is killing me. Thanks for any help.

I have found only three materials for this coil. Copper, aluminum, and anodized aluminum.

Time for more coffee.

I wanna say a copper/ruthenium alloy. Bleach dissolves ruthenium.

What?!!! A copper ruthenium alloy? Why on earth would they use a copper ruthenium alloy?!

Bleach dissolves ruthenium?!!!

Please don't post information unless you're sure of what you're posting.

Somebody tell Lou...poor guy is still using fluoboric acid and salt fusions to get it in solution. Could have just been using the janitors bleach.
