Ultra innovations led to the Galaxy S25 Edge: Yes, it’s a titanium phone

Samsung's first phone to use a titanium (grade 2) frame was the Galaxy S24 Ultra. This material helped the phone achieve a thinner profile than its Armor Aluminum-based predecessor. Then the Galaxy S25 Ultra debuted with a grade 5 titanium frame and an even thinner 8.2mm body.

Samsung's understanding of titanium expanded over the past two years. However, despite the company's growing expertise, there are limitations to how thin an Ultra phone can be. A super-thin Galaxy S Ultra may never be possible because of the S Pen. And that's where the story of the Galaxy S25 Edge picks up, right where the Ultra's left off.

Not wanting to let all its newfound engineering knowledge and understanding of high-grade materials go to waste, Samsung redirected its resources to create the Galaxy S25 Edge. The Edge is the one phone that truly tests titanium's qualities and pushes this advanced material to new limits.

The Galaxy S25 Edge is only 5.8mm-thin. It's way thinner than a standard pencil. It's the thinnest slab-type Samsung smartphone ever made. But thinness has no value if it compromises resilience. Thankfully, the clever use of titanium and Gorilla Glass Ceramic 2 gave the S25 Edge's streamlined silhouette “exceptional resilience,” Samsung says.

Samsung really appears to take a lot of pride in the design and engineering that went into the S25 Edge. Here's one way the company describes its new stylish phone:

Of course, everyone will want to see how the Galaxy S25 Edge lives up to these promises. We're not in the habit of bending phones, intentionally or not, but content creators who specialize in testing the durability of mobile devices will most likely put the S25 Edge through its paces.

It will be fascinating to see just how tough the Galaxy S25 Edge and its titanium frame are. Still, considering that Samsung can now create Galaxy Z Flip phones that don't bend at the hinge, even without using titanium, it's easy to assume that the Galaxy S25 Edge is just as strong as Samsung claims.
