About Titanium Nitride Coated Magnets

Medical industry is a relatively high-end application to the permanent magnets, especially in-body use. The FDA requires medical magnets must have approved biocompatible coating, such as parylene-coated magnets and Titanium Nitride coated magnets.

About Titanium Nitride Coating

As the fourth transition metal nitrides, Titanium Nitride had the characteristic of metallic crystal and covalent crystal combined rely on hybrid structure constituted of metallic bond and the covalent bond. Titanium Nitride coating has many merits, include high melting point and hardness, superior thermal properties, chemical inertness, conductivity and metallic reflectivity, therefore, Titanium Nitride coating can be served to different kinds of cutting tools and mechanical parts as hard wear-resistant film, and also can be applied to decoration industry as decorative film. Besides, Titanium Nitride thin film can be used as the conductive film and protective film of electrochromic device, or reflective film and antistatic film of display device. The optical properties of Titanium Nitride are very strange that has high reflectance in red waveband of the visible region, while has low reflectance near ultraviolet region and thus smoothly golden yellow in color which rival gold.

About Titanium Nitride Coated Magnets

LECMAG’S Customers may be more likely to confused Titanium Nitride coated magnets with everlube-coated magnets only from appearance. The high corrosion resistance and non-reactivity in the human body will ensure Titanium Nitride coated magnets slow down the release of the metal ion and reduce toxicity of metal material to the surrounding media.
