You should be able to get almost identical metal materials with Corona and Vray.
As already mentioned, the basic rule for metal materials is setting diffuse level to 0 (unless the metal is supposed to be dusty or covered with something non-metallic). Then adjust Fresnel IOR and glossiness, and you are done. :)
I am also attaching a screenshots showing a simple setup allowing you to easily fine-tune the glossiness of your material. Just use it with IR.
