Anodized Colored Titanium Fasteners

As core components of connecting structures, titanium fasteners are subject to performance requirements far exceeding those of ordinary metal fasteners. Anodizing, a core technology for surface modification of titanium fasteners, not only enhances corrosion and wear resistance but also enables precise control to achieve a rich, colorful appearance, adding both functional and decorative value.

The core value of anodized colored titanium fasteners lies in three key dimensions:

First, performance upgrade. The oxide film forms a strong metallurgical bond with the titanium substrate, resulting in salt spray corrosion resistance 5-10 times greater than untreated titanium. This allows for long-term, stable service in harsh environments such as marine environments and medical fluids.

Second, color customization. By controlling the oxide film thickness (10-300nm), the interference effect of light creates a full range of colors, from light yellow, sky blue, purple, to dark brown, with uniform, fade-resistant colors.

Third, application adaptability. In the aerospace industry, color can be used to distinguish different fastener specifications; in medical devices, it can meet biocompatibility requirements; and in high-end consumer goods, it can achieve aesthetic design.
