Niobium round bar is a solid metal product that is used in a variety of high-performance applications. It is renowned for its strength, corrosion resistance, and high melting point of 2468°C. It has a density of 8.57 g/cm³, making it heavier than other metals but lighter than tungsten. Parag Metals is a reputable niobium bar supplier, providing niobium alloy rods for a variety of industries. Each bar meets the chemical composition requirements for industrial and research applications.
Niobium bars are available in different forms and finishes to meet different application needs. We offer R04200 grade bars that are composed of high purity niobium. The typical diameter ranges from 3mm to 800mm. These niobium bars are supplied in finishes such as black, bright polished, rough turned, matte, and BA finish. Each niobium round bar and niobium square bar is processed using controlled methods to maintain consistent quality and surface finish.
