Apple’s Titanium Foldable iPhone Aims to Be Thinnest and Toughest Yet

A new foldable iPhone is in development at Apple. It could launch as soon as 2026. The device is rumored to be the thinnest iPhone ever made.

According to industry analysts, Apple plans to use a special blend of titanium and aluminum. This material choice is intended to make the phone incredibly durable while achieving a sleek, lightweight design.

Material Science Meets Mobile Design

Analyst Jeff Pu detailed the potential material use in a note to investors. He suggested the device, tentatively called the “iPhone 18 Fold,” would utilize a titanium and aluminum frame. This follows the successful use of titanium in recent iPhone Pro models.

The device’s thickness is a major focus. Reports from Bloomberg’s Mark Gurman indicate it will measure just 4.5mm when unfolded. That would make it thinner than the upcoming iPhone Air and very close to Samsung’s rival Galaxy Z Fold series.

A New Form Factor for Apple

This move represents Apple’s first entry into the foldable phone market. The company is betting on premium materials to differentiate its product. Using titanium could address common durability concerns associated with folding screens.

For consumers, this means a potential blend of luxury feel and robust construction. The phone is expected to feature a 5.5-inch external display. It would then open to reveal a 7.8-inch main screen, effectively merging two iPhone Air-sized devices.

Apple’s rumored titanium foldable iPhone could redefine premium smartphone design, combining extreme thinness with unprecedented structural integrity for a 2026 debut.
