Brass is stronger than aluminum nips
I have aluminum as well. For some superstitious reason I always get brass for the rear.myarmisonfire said:I've never once had a problem with aluminum nipples. I do suspect that the zinc content in brass nipples prevents galvanic corrosion with the stainless spokes. That being said I have always used a high zinc content anti seize labelled for aluminum when I have built my wheels.
They didn't fail at the thread. They fail at the rim nipple junction. The heads pop when they corrode through. There is probably enough friction at that point to wear through the anodizing and allow for corrosion to start.myarmisonfire said:I've never once had a problem with aluminum nipples.
