So that aluminum parts can fail and break under the load below their endurance limit. I realize that most climbing hooks on the markets are anodized and dyed. Why do...

    Different materials for bolts and nuts regarding galvanic corrosion?

    I did more research and expressed my concerned to my supervisor. He said the product won't be used under the environment where salt water is present. But other senior engineer is going to take a look at the paper to make sure whats going on. Thank you for the comments!

    Different materials for bolts and nuts regarding galvanic corrosion?

    Thanks TVP, According to the reference the difference in Titanium and S/S304 is only 0.03V. I suppose I don't have to worry about galvanic corrosion. I will look into crevice corrosion in seawater for SS304.
