Tantalum R05240 comprises 57.9–65 wt% tantalum with 35–42 wt% niobium, along with trace impurities such as tungsten, molybdenum, oxygen, carbon, iron, nitrogen, titanium, silicon, and hydrogen In the annealed condition, it exhibits a tensile strength of about 270 MPa (39 ksi), yield strength around 170 MPa (24 ksi), elongation near 25%, Young’s modulus ~150 GPa, and shear modulus ~57 GPa. Alternative sources indicate yield strength as low as 103 MPa and ultimate tensile strength around 241 MPa, still with 25% elongation

Thanks to its remarkable resistance to aggressive chemicals like hydrochloric, nitric, and sulfuric acids, Tantalum R05240 bars are highly valued in chemical processing equipment such as reaction vessels, heat exchangers, and piping systems. Their high melting point and thermal stability also make them suitable for aerospace, nuclear, and atomic energy applications, including components in high-temperature environments and thermocouples. Moreover, their combination of ductility, corrosion resistance, and strength makes them appropriate for medical implants and electronics manufacturing—especially capacitors and other components requiring reliability under thermal and chemical stress.
