Titan Basicline® is completely nickel-free and is suitable for sensitive and very allergic people. It is half as heavy as steel. It is not really the titanium itself that is so good for the body but the layer of titanium oxide that forms on the surface. The oxide layer also acts as a barrier against other substances in the titanium leaking into the body. If the titanium oxide surface is worn away, a new layer is formed immediately.
Aurumline® is jewelry that is bright, silvery in color even though it contains no silver at all. These pieces of jewelry are not "colored" in the classic sense, they are 316L Steel or Titanium covered with a thin plasma film of 24k gold (PVD coating). The thin film is very strong and does not fade. The technology has been used since the end of the 80s and is used, among other things, for implants to provide an extra hard-wearing surface.
