High melting point: Tantalum has a melting point of 2996 ℃, ranking third only to tungsten and rhenium. This allows tantalum screws to maintain stable performance in high temperature environments and is not easily melted or deformed, making them suitable for use in equipment and components that need to withstand high temperatures.

High strength: Tantalum has high strength and hardness, excellent tensile strength and yield strength, and can withstand large tensile and compressive forces, ensuring the firmness and reliability of the connection parts. It is suitable for structures with high requirements for connection strength.

Corrosion resistance: Tantalum has excellent corrosion resistance to many corrosive media at room temperature, including acid, alkali, salt solutions, etc. In the fields of chemical, marine, food, etc., tantalum screws can resist the erosion of various corrosive substances and extend the service life of equipment.

Good biocompatibility: Tantalum has good biocompatibility, is non-toxic, harmless, and does not cause adverse reactions to human tissues. Therefore, it has important applications in medical devices, bioengineering, and other fields, such as manufacturing fixing screws for artificial joints, dental implants, etc.
