No. Our products are coated using a high quality PVD process (Physical Vapour Deposition), it is a process carried out in high vacuum at temperatures between 150 and 500 °C, using Titanium coating which is also hypoallergenic in nature. The process has been used since the 1990's to increase durability and reduce friction, it's even been used in F1 car engines!
