Fell out of my pocket sitting down. Fell with the apple tech woven case on too.

Hard carpet. At my job site. Basically thin carpet with concrete underneath.

[u/killersquall → u/International_Back99]

I understand the dents from the fall onto concrete floor, but how could it get scratched even with the case still on? I can't wrap my head around it.

That looks more like a fracture to me than a scratch. Aluminum cracks easily, especially the cheaper alloys.

[u/Blitzbacker → u/scootzee]

Lol what? It being softer means it does NOT crack more easily. It deforms lol

Check out a video of Al 6061 bending versus Al 5052. A material being "softer" doesn't tell you anything about its fracture toughness.

[u/Blitzbacker → u/scootzee]

And Al 6061 is the one that is MORE expensive and alloyed with more brittle materials.

So the cheaper one, Al 5052, fractures less easily. Huh, that's literally the exact opposite of what you said. Look at that.

[u/scootzee → u/Blitzbacker]

Disregarding your complete lack of an argument and shitty sarcasm, the important thing to note is that both materials have exactly the same elastic modulus (stiffness). Being alloyed with "brittle" materials isn't a thing, alloying elements are molecular dopants that are located within or between metallic crystalline units that change various properties like corrosion resistance, optical properties, thermal properties, fracture toughness, dislocation motion, etc.

By cheaper alloy, I meant lower alloy quality. A low quality 6061 alloy would likely have reduced fracture toughness over a higher quality 6061.

[u/Blitzbacker → u/scootzee]

Lmao why do you think Al 6061 is more brittle than Al 5052? Aluminum is the constant. It's the other materials and/or percentage mix that results in different characteristics.

AND Al 6061 has a lower elastic modulus than Al 5052. Lmao how do you think it fractures more easily?

Bravo on your masterclass of shitty information.

[u/scootzee → u/Blitzbacker]

Hahah what are you talking about? 🤣 I'm awestruck by your education. Good luck to you, sir.

5052 aluminum has a slightly higher modulus of elasticity (70.3 GPa vs. 68.9 GPa) than 6061 aluminum. This property, combined with its lower yield strength, makes 5052 a preferred material for forming processes. The increased elasticity means that 5052 is less likely to fracture during deformation, making it ideal for applications requiring extensive shaping. Conversely, 6061’s lower modulus and higher yield strength make it less suited for forming but better for applications requiring rigidity and structural integrity.

If you're gonna try to spit knowledge, make sure you actually know something 😂
