Hi!
Are you sure that would really be lighter? Delrin is rather heavy.....

Acetal is about 1.4 SG. Alum is about 2.6 SG.
If the volumes stay the same an AL piece would be 1.85 as heavy as the acetal piece. If you can machine away more of the AL because of it's greater strenght you might end up lighter.
