Tantalum R05255 Sheets and Plates, offered by your company, are top-notch tantalum-tungsten alloy products designed to excel in harsh, corrosive, and high-temperature environments. These materials meet established standards (like ASTM B708 / ASME SB708) for sheet and plate manufacturing, guaranteeing consistent quality and dependability. The alloy typically consists of about 90% tantalum and around 9–11% tungsten, with minimal impurities such as carbon, oxygen, nitrogen, hydrogen, iron, silicon, and other trace elements.
When in the annealed state, R05255 sheets and plates exhibit impressive mechanical properties: an ultimate tensile strength of approximately **482 MPa (about 70,000 psi)**, a yield strength ranging from **379–414 MPa (around 55,000–60,000 psi depending on thickness)**, and an elongation of typically **15–20%**. The material also boasts a high density (approximately **17 g/cm³**) and commendable thermal properties, including stable performance at elevated temperatures and decent thermal conductivity for a refractory alloy.
