The wheels use rather large sprockets, with many teeth, and usually the chain wraps more than half way around the sprocket, so the load on each tooth is relatively small. The aluminum sprockets are strong enough for use on wheels, and the smallest size you can commonly get is 24 teeth, I believe.
However, the transmission sprockets are a different story. Some use as few as 9 teeth, so the load per tooth is significantly higher.
The general way of doing things is to use steel sprockets at the drive end of the chain, and aluminum sprockets at the wheel end of the chain. It works.
