Barsham Nickel Alloys, Doha, Qatar, is a premier producer and distributor of high-performance nickel alloys and specialty metals. We strive to provide high-quality products and superior service in multiple industries. Our Niobium Bar is one of our top products, renowned for corrosion-resistance, high melting point, and superior strength at high temperatures. Perfect for aerospace, electronics, and chemical processing applications, we deliver on time with reliable solutions meeting individual customer requirements across the globe.
Niobium Bar consists mainly of 99.9% pure niobium, with high strength and excellent corrosion resistance. The mechanical properties are tensile strength of approximately 550 MPa, with high ductility and formability. Niobium has a melting point of about 2,477°C, making it suitable for high-temperature applications. The bar also has high resistance to oxidation and corrosion in harsh environments, such as aerospace, electronics, and chemical processing. Physically, niobium is heavy, with a hardness of about 60 HB, and remains stable even at cryogenic temperatures, guaranteeing reliability in harsh conditions.
