Apple Card Not 100% Titanium, as per Mineralogist

Bloomberg Businessweek wanted to find out just how much titanium was in an Apple Card. They sent it off to be put under the microscope to Hans-Rudolf Wenk, Berkeley University mineralogist and professor. The answer? The Apple Card is 90 percent titanium and 10 percent aluminum.

The Berkeley professor used an SEM device, or scanning electron microscope to determine the actual composition of the card. The atomic makeup reveal that most are titanium, while a small percentage is aluminum.

Apple Card Not 100% Titanium

Apple has announced before that the characteristic white finish was the result of multi-layer coating done on base titanium material. The Cupertino-based company has also mentioned that the coating may be damaged if it scrapes or bumps into hard materials or surfaces. Denim or leather may cause the coating to warp or become permanently discolored.

Apple Card went live on August and is the first non-bank credit card without late fees. Right now it’s only available in the US, with plans to spread out to other parts of the world.
