Bhansali Enterprise is the top manufacturer and supplier of tantalum round bars. Tantalum is a strong refractory metal, similar to molybdenum and tungsten. It has a high melting point and can withstand heat and wear. Tantalum bars are well-known for their high corrosion resistance, even in harsh acids and aqua regia below 150°C. They are easily shaped and bent due to their high ductility. A natural oxide layer forms on the surface, offering additional protection. We keep a wide tantalum bar stock and offer tantalum threaded options. As reliable tantalum rod suppliers, we provide high-quality products to meet your needs.
Tantalum alloy bars are high-performance materials commonly used in carbide tools. We provide top-quality Tantalum R05400 Rods that meet ASTM B F560-98 standards. Tantalum has a very high melting point—2996°C—and can withstand most acids. It can only react with hydrofluoric acid, strong alkalis, and hot sulfuric acid. These rods have excellent thermal conductivity and are simple to work at room temperature. Though the material is expensive, its unique properties make it worth the cost. We also offer UNS R05252 and UNS R05240 grades in single-piece lengths for various project requirements.
