Handling and Storage of TiNb Alloy Powder

As a reactive metallic powder, some care is needed when handling TiNb alloy powder:

Store in sealed containers in a dry, inert atmosphere to prevent oxidation and contamination

Avoid contact with oxygen, moisture, oils, combustible materials

Prevent accumulation of fine powders on surfaces or equipment

Ground all conductive equipment used in handling

Use spark-proof tools and minimize dust generation

Wear gloves and respiratory protection when handling

Use grounded ventilation systems and avoid dust clouds

Keep away from heat, flames, sparks and other ignition sources

Follow safety data sheet for proper PPE and precautions

If stored properly in a dry, inert atmosphere, TiNb alloy powder has a typical shelf life of 12 months. Improper storage conditions can lead to oxidation, loss of flowability, or ignition hazards.

Medical Applications of TiNb Alloy

Due to their biocompatibility, high strength and low modulus, TiNb alloys are widely used for medical implants and devices:

Orthopedic Implants

Knee and hip replacements

Bone plates, screws

Spinal fixation devices

Dental implants and bridges

TiNb alloys like Ti-35Nb and Ti-45Nb match the elastic modulus of human bone while providing high fatigue strength. This reduces stress shielding compared to stiffer titanium alloys.

Cardiovascular Devices

Stents

Pacemaker casings

Guidewires

Surgical instruments

The corrosion resistance, non-toxicity and non-magnetism of TiNb alloys make them suitable for devices that contact blood and tissues.

TiNb Alloy Grades for Medical Use

Ti-10Nb to Ti-50Nb

Ti-Nb-Zr, Ti-Nb-Ta for adjusted properties

ISO 5832-11 and ASTM F2066 standards

Lower modulus Ti-35Nb and Ti-45Nb are commonly used. Higher Nb strengthens but increases modulus. Small Zr/Ta additions further tailor properties.

Advantages of TiNb Alloys for Biomedical Use

Excellent biocompatibility and osseointegration
