Frequently Asked Questions

Why use Titanium Nitride (TiN) over other coatings?

Titanium Nitride coating offers superior hardness, excellent wear resistance, and biocompatibility, making it ideal for medical applications.

Can Titanium Nitride (TiN) coated magnets withstand repeated cleaning?

Yes, the coating is very durable and maintains its integrity under repeated
sterilization cycles.

What is the appearance of Titanium Nitride (TiN) coated magnets?

TiN produces a darker gold-colored finish that is both attractive and functional.

Is Titanium Nitride (TiN) coating thick?

No, the coating is extremely thin (typically 3–6 μm) and does not significantly
alter the magnet's dimensions. See our coating specifications for more details.

Can you produce custom sizes, magnetization direction or coatings?

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
