iPhone Ultra will have one feature Apple has been developing for 15 years

The iPhone Ultra is coming this fall after years of leaks and rumors. Apple's first

foldable phone has been showing up in alleged real-life footage, its specs have been all over the internet, and we know pretty much everything about the new Ultra.

But the latest information focuses on one tech Apple has been working on for 15 years. And it looks like it will find its way to the hinge of the iPhone Ultra.

iPhone Ultra will most likely have liquid metal in its hinge

The latest leak comes from Chinese tipster

Fixed-focus digital cameras and basically confirms that the iPhone Ultra will use liquid metal in its hinge. Here's what the post reads (translated from Chinese):

Latest confirmation: Apple has chosen a liquid metal hinge solution for its foldable screen. Furthermore, research and development and production are progressing rapidly, and prototypes have already been sent to carriers worldwide for testing.

Earlier leaks from industry insider Ming-Chi Kuo also pointed toward luquid metal allow for the hinge of the

foldable iPhone, but this latest post claims to be a "confirmation."

According to Fixed-focus digital cameras, prototypes have already been sent to carriers and partners, so the latest leaked iPhone Ultra images might very well be real.

This isn't the first time "liquid metal" has been mentioned next to the phrase "foldable iPhone." The first such mention dates way back to the year 2010.


Apple filed "liquid metal" patents back in 2010

Apple licensed the tech 15 years ago, filing two patents with the inventors of the technology, Atakan Peker and Bill Johnson.

The tech was developed at the

California Institute of Technology, and Apple is currently using it to manufacture the SIM ejector tool for its mobile devices.

The deal between Apple and

Liquidmetal Technologies was renewed in 2015 and is still active to this day.

What is "liquid metal?"

Liquid metal is the commercial name for a series of complex alloys developed back in the 2010s at Caltech.

Liquidmetal alloys combine a number of desirable material features, including high tensile strength, excellent corrosion resistance, a very high coefficient of restitution and excellent anti-wearing characteristics, while also being able to be heat-formed in processes similar to thermoplastics.

Contrary to what the name might suggest, these alloys are not liquid at room temperature. The tech has been in use in protective coatings for golf clubs, watches, and other heavy-duty equipment.
