Anodizing aluminium reduces fatigue strength. what about climbing hook?
(OP)
Hi,
While I was researching about anodizing aluminum I learned that anodizing aluminum reduces fatigue strength of the material.
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 they anodize climbing hooks? This doesn't make sense to me because they are very safety critical!
Maybe I am misunderstanding something here but this made me really puzzled.
Any thought? comment?
Thanks,

Protection from corrosion, which also reduces fatigue strength -- as long as there are no scratches through the anodizing!
