Briefly

The wafer-thin iPhone Air is surprisingly strong.
"You'd be forgiven for assuming the iPhone Air would snap like a twig under pressure. It's almost impossibly thin at just 5.6mm. But, its titanium frame is not only stronger than aluminum, it's also more elastic. YouTuber JerryRigEverything demonstrates this with his usual bend test. While he's able to get some slight bowing by pressing his thumbs into the center of the screen with all his might, it doesn't crack and immediately returns to its original shape."
"Not content to be thwarted by Apple's engineering team (and perhaps feeling a little disappointed that the last several devices on his channel survived the bend test), JerryRigEverything takes a trip out to his garage. With the help of a crane scale and some metal bars he's able to find out exactly just how much pressure it takes to crack the iPhone air - 216 pounds."
The iPhone Air measures 5.6mm thin. Its titanium frame is stronger and more elastic than aluminum. A bend test applying full thumb pressure to the center of the screen produced slight bowing but no cracking, and the screen immediately returned to its original shape. A subsequent controlled test using a crane scale and metal bars determined the device cracks under 216 pounds of pressure. The titanium construction provides resilience against bending despite extreme thinness. The results indicate design priorities that balance minimal thickness with structural elasticity to resist deformation under force.
