I use it for aluminum and it works well. It is important that the tip is lubricated to avoid friction welding the aluminum to the torch. I've used it on several projects and it's as good or even better than the original.
Pros
3-tooth design for smoother, quieter milling^High productivity, ideal for pocketing in steel, titanium and exotic alloys^Ideal for long-reach peripheral milling^Titanium Aluminum Nitride (TiAlN) combines high thermal stability with excellent hardness for abrasion resistance and low coefficient of friction, for lubrication^Center tipped end mills have "end teeth" making them ideal for slotting and cavities
