Some, or perhaps most, hollow axles are made of higher-grade steel than most solid axles, but that's because solid axles are for generally used for the least expensive hubs. In any event, the difference in strength between a solid axle and a hollow axle of the same diameter is minimal, as demonstrated by the predominance of hollow axles on better bikes..
