I have a passing acquaintance as well, I've used it to make connecting rods in miniature engines. The strength/weight ratio allows the rod to be made lighter thus reducing vibration, there is no way to properly balance a one cylinder engine. It needs a bronze bushing to wear well, and machining requires a light cut, fairly high surface speed, and plenty of coolant.
