I Hate Amazon's 12kN Carabiners (Patreon)

Content

The 12kn carabiners being made today look and feel like climbing carabiners and can easily get mistaken as life supporting devices.  Even the description videos and reviews on these products mistake them for climbing use.  You need your aluminum stronger than you need it so it doesn't get fatigue and suddenly snap on you.  The carabiners we broke were all higher than 12kn in this episode but that doesn't mean they are proof loaded and meet the standards for climbing today.   

DO NOT BUY THESE - these links are just for you to reference the carabiners we tested in this episode.  We literally threw away the extra ones we did not break or use so they don't accidentally get mixed into my gear

That is all very interesting... so is all climbing gear made of aluminum made with 7075?

Yep, either the 7075 or another "7000-series" (or 7XXX) aluminium alloy. It is the same Alloy family used to make parts in airplanes and even some rockets! This is from the DMM Website (about anodizing): "This is largely because the alloy used to make most climbing carabiners - 7000 series aluminum alloy - is quite susceptible to galvanic and exfoliation corrosion: this alloy series has zinc as the primary alloying element together with magnesium. The further addition of copper to the aluminum-zinc-magnesium system together with small, but very important amounts of chromium and manganese gives high strength aluminum alloys that, although initially developed in 1943, are still the benchmark for use in climbing carabiners." [https://dmmclimbing.com/Knowledge/August-2011/Anodising] Fun extra fact: This kind of Aluminum (7xxx, but also the 6xxx and 2xxx) can be molded in the factory in a pretty "soft" state from a straight rod into the complex cross-section carabiners we use. Then, once in it's final shape, it is has this heat treatment done to it, which massively increases it's strength (while decreasing the ductility- capacity for plastic deformation. But this is done in a controlled way to still have some bending and deformation before snapping. Like you've seen many many times already ;))

Very interesting. Do you think these carabiners only are missing the heat treatment then? I've also seen corrosion on aluminum carabiners in caves which is very interesting.
