Lightweight titanium alloys for smart wearable applications

Titanium alloy is an advanced lightweight structural material with the advantages of lower density than stainless steel, good biocompatibility, high texture, non-magnetic, non-allergic, excellent corrosion resistance, as well as high specific strength, and it is gradually becoming one of the favoured materials for consumer electronic products. At present, many wearable products, including smart watches, smart glasses, smart rings, etc., are increasingly using titanium alloys to prepare exterior parts and key components.
