After the arrival of the 5G era, mobile phones have to be equipped with large batteries and antennas, so the weight of flagship mobile phones is generally above 200g. Many consumers complain that their phones are too heavy and feel sore wrists when playing in bed. In order to change this status quo, Apple has set its sights on the titanium alloy.
The advantage of titanium alloy is that under the same strength, the density is much lower than other commonly used metals. Now that Apple uses titanium alloys on mobile phones, it will undoubtedly greatly increase the durability of mobile phones and reduce the weight of mobile phones. However, this material also has some disadvantages. Oil stains on the fingerprints are left on the titanium alloy surface, leaving unsightly marks on the phone. The hardness of titanium also makes it difficult to etch, which makes adding design more difficult. Apple has been studying how to overcome these two problems.
Recent patent applications indicate that Apple is considering the use of thin oxide coatings on metal surfaces, which can significantly reduce fingerprints on mobile phones. The company also outlined various sandblasting, etching, and chemical processes that can make the titanium casing have a high gloss, which makes the appearance more attractive. This is undoubtedly a big improvement.
