Is it OK to use aluminum lug nuts on a steel wheel?

I would not use aluminum lug nuts on steel wheels. I might consider it if the wheel and nut had large contact surfaces that matched each other.

Porsche has been using aluminum lug nuts on aluminum wheels on street cars for a few decades now. I think they started with 911's in 1964 but maybe some 356's had them. They had a service bulletin instructing the use of anti seize on the lug nuts because there were too many nuts sticking to the wheel, making removing them quite difficult. Clean bare aluminum nut hammered in place with an impact gun tended to weld them selves to the wheels.
