Medical Devices

Dong-A Special Metals, Inc. proudly introduces Titanium-Zirconium (Ti-Zr) alloys, a next-generation material engineered to meet the demands of high-tech and medical industries. These alloys are designed for high strength, exceptional corrosion resistance, and excellent biocompatibility, without relying on allergenic elements such as nickel or aluminum.


What Are Ti-Zr Alloys?

Ti-Zr alloys are formed by combining titanium (Ti) and zirconium (Zr)—two transition metals with similar atomic structures and chemical properties. They are fully miscible, creating either a single-phase α-type structure or a dual-phase α+β-type structure, which enhances both mechanical strength and machinability.

This alloy system also benefits from a uniform oxide film that offers outstanding corrosion resistance, especially in physiological environments and high-salinity industrial settings.


Key Properties of Ti-Zr Alloys

- Corrosion Resistance: Superior to pure titanium, especially in body fluids and marine-like environments

- Mechanical Strength: Increased tensile and yield strength due to refined grain structure

- Biocompatibility: Non-toxic and free from allergenic elements like Ni and Al

- Thermal & Structural Stability: Maintains ductility and toughness under high loads and temperatures

- Hydrogen Compatibility: Low corrosion in hydrogen-rich environments, ideal for hydrogen economy applications


Applications of Titanium-Zirconium Alloys

Ti-Zr alloys are increasingly used in:

- Medical Devices: Implants, surgical tools, and prosthetics

- Chemical Process Equipment: Reactor vessels, pipe fittings, and heat exchangers

- Nuclear & Semiconductor Components: Where minimal metal ion contamination is critical

- Hydrogen Storage and Fuel Cells: For solid-state hydrogen storage and sensing devices

- 3D Printing & Powder Metallurgy: Due to excellent hot/cold workability and formability


Manufacturing Process

Ti-Zr alloys are typically produced by:

- Vacuum Arc Remelting (VAR)

- Induction Skull Melting (ISM)

To maintain quality, trace impurities such as oxygen, carbon, and iron must be strictly controlled—especially for medical and semiconductor-grade materials. The alloys also offer excellent formability and are available in ingot, rod, wire, sheet, and powder forms.


Future Outlook

As global demand for biocompatible, reliable, and environmentally safe materials grows, Ti-Zr alloys are expected to play a critical role in:

- The medical device market

- Hydrogen-based energy systems

- Next-generation semiconductor manufacturing

Ongoing research continues to enhance the performance of high-purity Ti-Zr alloys, ensuring they remain central to sustainable, high-performance engineering solutions.
