Tantalum is a rare metal with an extremely high melting point and high corrosion resistance, especially in acidic and alkaline environments. Because of these properties, tantalum is used in numerous industrial applications as a material for fasteners, often where extreme corrosion resistance and high temperature stability are required.
Tantalum Alloy Fasteners details
Key feature
1. Very high density of 16.66 gm/cc
2. Radiopaque to x-rays and other radiation – even higher than lead
3. Excellent high temperature strength and stability (vacuum)
4. Very corrosion resistance
5. Good low magnetic properties
The aerospace industry depends on the tantalum bolts for their combination of high density and mechanical strength which allows
them to reduce the physical size of components, offering greater control of weight distribution for propellers, inertial systems
and fluid control systems to name a few.

Application
Tantalum is widely used in aviation and aerospace industry, high temperature technology, atomic energy industry and chemical industry thanks to its high melting point, corrosion resistance and good cold working performance.
Characteristics of tantalum fasteners:
1. High corrosion resistance: Tantalum is resistant to corrosion by most acids, including hydrochloric acid, nitric acid and sulfuric acid.
2. Excellent biocompatibility: Tantalum has excellent biocompatibility with human tissue, so it is often used in medical devices.
3. High density: Tantalum has the highest density among all non-alloy metals (16.65 g/cm³).
4. High melting point: The melting point of tantalum reaches 3017°C, making it suitable for applications that require high temperature resistance.
5. Excellent electrical conductivity: Tantalum also has good electrical conductivity, second only to silver, copper and gold.
6. Good mechanical properties: At room temperature, tantalum has high ductility and tensile strength.
Application areas:
1. Chemical Equipment: In the chemical processing and petroleum refining industries, tantalum fasteners are used in equipment that comes into contact with highly corrosive chemicals.
2. Medical devices: Due to its excellent biocompatibility, tantalum is often used in orthopedic implants, dental implants and other medical devices that remain in the human body for a long time.
3. Aerospace: Considering its high temperature resistance, tantalum fasteners are used in the aerospace field for engines and other key components of aircraft.
4. Electronic industry: Tantalum is also used in the manufacture of capacitors and electronic components because its anodized film has a high dielectric constant.
Tantalum fasteners provide unparalleled performance in specific applications, especially where extreme corrosion resistance and high temperature resistance are required. However, their use is usually limited to those areas with extremely high performance requirements, and cost and resource constraints make them unsuitable for a wide range of general-purpose applications.
