DT Swiss Standard Aluminum Nipples offer an easy way to shave weight at the rim interface for minimal cost. 

Aluminum nipples weigh about one-third the mass of a brass nipple making them a great option for weight savings at the rim/spoke interface.

Wheelbuilder does not recommend using alloy nipples in wet or salty environments due to their limited corrosion resistance.
