Metal . Many cell phones, including the iPhone 6 and Samsung Galaxy S6, have metal bodies. So it makes sense that you can get metal bodied cell phone cases as well. Aluminum is the most common metal used in cell phone cases. You can also purchase cell phone cases made with titanium, brass and precious metals like gold.
Finally, polycarbonate is more likely to acquire fingerprints, grease and sweat than a softer case, making the phone look less polished than with other types of cases. The choice of smartphone cases is up to you, and if you decide you’re partial to polycarbonate cases, you have a lot of options to choose from.
This case is made of Thermoplastic Polyurethane (TPU), which combines the advantages of a soft silicone case with the protection of a hard polycarbonate case. It is flexible and is easily installed on your watch. It has cutouts on the side for the Digital Crown, a cutout on the back for the heart rate sensor, and a button extender over the right side action button.
The Tough Armor case for the iPhone 6 (4.7) is the new leader in protective cases providing better impact absorption than other boxy/bulky cases in the market. The Tough Armor® case for the iPhone 6 provides impact absorption while staying less bulky than other protective cases.
