Titanium alloy can meet the multiple needs of 3C electronic weight reduction, robustness, wear resistance and so on. Titanium alloys have high specific strength, low density, corrosion resistance and high biocompatibility, and are used in 3C electronics to enhance their rugged performance and lightweight properties. At present, some models and wearable devices have used titanium alloy in the frame, backplane, hinge, such as iPhone 15pro series, Apple Watch Ultra, Xiaomi 15 pro titanium series, Samsung Watch 5 pro, Honor MagicV2 folding screen.

Titanium alloy can improve performance and use experience from the following aspects:
Strong, durable weight reduction
Taking iPhone 15 Pro series as an example, the GR5 (Ti-6Al-4V) titanium alloy used is α+β titanium alloy. GR5 titanium alloy is also the most used titanium alloy at present, accounting for more than 50% of the total output of titanium alloy. It has good thermal strength, corrosion resistance and low temperature toughness. It is widely used in aerospace fields such as rocket shell and spacecraft, so it ensures the robustness and durability of the product.
Good biocompatibility
Some metal elements are easy to react with salt ions in human sweat, making metal elements more active (ionization), penetrating into the skin to cause metal allergies, common elements that are easy to cause metal allergies are nickel, cobalt, chromium. Titanium alloy has good compatibility with human tissue and blood, and is a biophilic metal, which can be made of titanium in medicine to implant artificial bones in the body, and making product shells with titanium alloy can avoid metal allergy.
Beautiful, do not leave fingerprints
Titanium alloy hardness, small thermal deformation, corrosion resistance, and biophilic metal, so to ensure that the mobile phone or watch shell is not easy to deformation, scratch, bump and fade, do not leave fingerprints, enhance product beauty.
