Neeka Tubes is a Wire is made up of niobium. These are made up of commercially pure niobium grades. There are two types of niobium grades. The grade 1 has less than 0.1% impurities in it and is called the reactor grade. The type 2 is called the commercial grade and has less than 0.2% of impurities. Navstar Steel is a supplier of the Niobium Wire 20 Gauge and other various dimensions.

The material has 125MPa minimum tensile strength and 73MPa minimum yield strength. The applications are of high end. The reactor grade is used in particle accelerators while the commercial grade Rainbow Copper Wire Price is lower than that of the reactor grades. The commercial grades are used in superconductors and in high end electronics. The Copper 20 Gauge Wire has a very high melting point of 2468 degrees Celsius which makes it suitable for high temperature nuclear power applications. There are different sizes for the plates, rods, wires and tubes depending on the customer demand
