Breakthrough Colors for Titanium Anodizing
APT’s proprietary anodic film technology delivers high-quality titanium anodizing with exceptional consistency, production-scale throughput, and competitive processing costs. Tight process controls provide repeatable, brilliant-color finishes from lot to lot, making the technology particularly well suited for demanding medical device and precision component applications.
Titanium anodizing is commonly used for dental implants, spinal implants, bone screws, and other medical components where surface quality and consistency are critical. The process creates a controlled titanium dioxide layer that can exceed 2.5 µm in thickness, providing a durable and uniform anodic surface. APT’s titanium anodizing capabilities support applications requiring compliance with recognized industry standards, including AMS 2487 and AMS 2488.
Color Without Dyes
Anodizing titanium generates a wide array of colors without using dyes. This process has been widely accepted to differentiate medical components such as bone screws — different size components are coded by color to assist the surgeon during surgery.
Color is dependent on the thickness of the oxide layer, which is determined through precise process control. It is caused by the interference of light reflecting off the oxide surface with light traveling through it and reflecting off the underlying metal surface:
- Destructive interference — when the wavelengths of reflected light are out-of-sync, they cancel each other, and the visible color will be dark or not visible at all.
- Constructive interference — depending on the thickness of the anodized oxide layer, the reflected wavelengths follow each other closely and stay in sync. The wave amplitude increases, and that particular color appears brighter.
High Performance Titanium Anodizing for the Medical Industry
APT’s precision-controlled titanium anodizing processes deliver consistent, brilliant color and repeatable quality across every production lot. From medical devices and spinal implants to orthopedic components and bone screws, APT supports both specialized and high-volume production requirements with scalable, cost-effective processing. This combination of quality, consistency, and production efficiency makes APT’s titanium anodizing capabilities well suited for a wide range of demanding applications and industries.
