In the intensive media coverage, Apple's Apple Card has become a hot object in the United States. Many people are very interested in the unique material of this card. To this end, Bloomberg Businessweek reporter teaches to the University of California at Berkeley, a mineralogist. Hans-Rudolf Wenkke sent an Apple Card to determine the material composition of the card. The answer is already: 90% titanium and 10% aluminum.

Professor Wenk uses a scanning electron microscope (SEM) device to determine the material composition of the card. Apple previously said that the card's white surface treatment was achieved by adding a multi-layer coating process to titanium-based materials.

However, the use of unique alloy materials can have a gorgeous appearance, but it is difficult to achieve lasting. In a recent supporting document, Apple said that if the card is in contact with a hard surface or material, the coating may be damaged. Apple also said that some fabrics, such as leather and denim, may cause the card to be permanently discolored and difficult to wash off.
