Why this rock is probably not a meteorite:

The person who sent this metal piece to me said that it was one of many found in the Nevada desert 75 years ago. It's not a meteorite because it doesn't show any evidence for atmospheric ablation.
What is it?

It's some chromium-iron alloy with some impurities. Perhaps today it would be called ferrochrome or ferro chromite. Hard to say how it got to where it was found.
