Hmmmm.... You gonna make make me crawl under there? I know my car is the same lug nuts on the steel spare rim and the alum. wheels. Just swapped them for a flat this week. They may not be the same seat angle but they work fine for a trip to the tire store.
If you do a search you will find that it is the shape of the hole- Conical vs Spherical more so than the type material. If there is a question I would get answers before the fact. Usually the mfg will not mix the 2 on a vehicle cause who carries a extra set of nuts?
