What materials is the Oura Ring made of?
Have you ever wondered what the Oura Ring 4 is made of? It's not made of gold or silver, so what material is it? Check out this guide to find out.
The Oura Ring 4 has hit the market, featuring a renewed design and new functionalities. This smart ring is characterized by its simple and round appearance, allowing it to look like a conventional ring. The improvement in the accuracy of health readings has been achieved by relocating the dome-shaped sensors, along with the introduction of a platform called Smart Sensing, which collects data from 18 different pathways. This device is expected to rank among the best smart rings available.
Regarding the materials, despite its varied range of finishes, the Oura Ring 4 is made of titanium. This material is lighter than gold, yet boasts great strength, being the strongest metal on the periodic table due to its high strength-to-weight ratio. Its density is 4.5 grams per cubic centimeter and it has a hardness of 6.0 on the Mohs scale, compared to gold, which has a density of 19.3 grams and a hardness of 2.5. Due to its lightness, titanium is a comfortable material to wear on the finger, although it may lack the "premium feel" that precious metals possess, which can make it seem less valuable, although this is not the case.
Titanium, which is biocompatible, does not react adversely with the body, making it a popular choice for various jewelry, from earrings to bracelets. Additionally, it is hypoallergenic, which is essential for those suffering from certain skin conditions. It is a durable material, resistant to deformation and scratches, but it can still sustain some damage. Moreover, it can scratch other jewelry made of softer metals, such as sterling silver, so it is advisable to avoid contact with such items. When wearing the Oura Ring, it is recommended not to combine it with other rings to prevent them from being scratched.
In terms of colors, the Oura Ring 4 is available in black, silver, Stealth, brushed silver, gold, and rose gold. The black and Stealth rings feature a physical vapor deposition (PVD) coating on their exterior, while the other colors have a diamond-like carbon (DLC) coating. The black ring, with its shiny tungsten PVD coating, offers enhanced durability. The brushed silver model employs a vertical brushing technique that allows light to reflect from different angles, enhancing the properties of titanium. Meanwhile, the Stealth ring, with a matte black finish, adds a level of precision and detail. The silver and gold rings feature a shiny finish, while the rose gold ring has a finish designed to develop a darker patina over time, depending on use and care.
