Renthal 2240-520-48GPSI Twinring Silver 48 Tooth Rear Sprocket Review

Steel teeth outlast aluminum alloy by 3-4 times, but steel sprockets weigh a lot more, and that weight/mass is rotating mass.
Renthal has a patented design that combines a center made of their high-strength, lightweight, 7075 aluminum alloy with an outer teeth ring of steel. The two parts are mated together by heating the outer ring and freezing the inner making a super-tight press fit that is then further strengthened by flush fit rivets to lock everything together.

Don't let the higher initial cost of the sprocket to discourage you from purchasing one... In the long run they are half the cost of all aluminum rear sprockets.
