It could be a host of things really.
Delrin is actually easier to manipulate on the machines than ABS.
So from a manufacturing perspective, it's probably easier for them to mass produce than say...aluminum. But then again, Delrin is pretty expensive.
From a functionality point of view, even though it's "plastic", its almost the most perfect substitute for aluminum. Delrin is very high in density, making it almost equally resistant to impact as aluminum...
