Based in Kolkata, India, Khush Sheets and Plates is a top producer and supplier of Niobium Sheets and Plates, providing specialised industries with high-quality refractory metal products. Niobium is used extensively in cutting-edge engineering and technology applications due to its high melting point, exceptional mechanical qualities, and resistance to corrosion. To satisfy international standards, our niobium sheets and plates are produced with meticulous attention to detail and stringent quality control. We provide products designed for harsh environments and vital applications to industries like electronics, nuclear, chemical processing, and aerospace, all while maintaining a dedication to performance, dependability, and on-time delivery.
With trace amounts of tantalum, iron, and tungsten, 99.9% pure niobium makes up the majority of niobium sheets and plates. This high-purity metal has outstanding thermal and electrical conductivity, a melting point of 2477°C, and a density of 8.57 g/cm³. Depending on temper, it has a tensile strength of roughly 275–400 MPa, a yield strength of 150–275 MPa, and an elongation of ≥30%. Niobium is appropriate for demanding industrial and scientific applications because it is highly workable, resists corrosion in acidic environments, and retains its ductility and strength even at cryogenic temperatures.
