Pure Tantalum Rod Mechanical properties
✔ Annealing state (soft state)
Tensile strength of 220-260 MPa, elongation at break of 35% -45%, suitable for cold processing such as deep drawing and stretching.
At high temperatures (such as above 1000 ℃), the strength gradually decreases, but the plasticity significantly increases, and the elongation at break can reach over 50%.
✔Unanealed state (hard state)
Tensile strength ≥ 300 MPa, low elongation (about 10% -20%), suitable for manufacturing fasteners or structural components that require high hardness.

4.Pure Tantalum Rod Application Fields
1. High temperature industrial equipment
Vacuum furnace components: such as heating elements and heat shields, can withstand high temperatures above 2000 ° C and will not deform after long-term use.
Corrosive environment fasteners: Replace stainless steel in chemical reaction vessels and acidic medium pipelines to avoid corrosion leakage.
2. Electronics and Energy
Sputtering target material: used for tantalum film deposition in semiconductor and display manufacturing, requiring 99.99% ultra-high purity.
Nuclear industry components: As fuel cladding materials, they have both high temperature resistance and radiation resistance.
3. Medical and Precision Instruments
Surgical implants, such as bone nails and joint fittings, utilize their biocompatibility and corrosion resistance.
X-ray/Radiation Shielding: High density tantalum rods can block high-energy radiation and are used as protective layers for medical equipment.
