Niobium rod is a highly high-temperature, corrosion-resistant metal material with a variety of unique properties. First, it has an extremely high melting point, reaching about 2,477 degrees Celsius, which makes it stable in extremely high temperature environments.
Second, Nb rod shows excellent mechanical properties, with good strength and hardness, so that it can still maintain a stable structure under high temperature and pressure.
In addition, Niobium bar has good corrosion resistance to many chemicals, including acids, alkalis, salt solutions, etc., making it capable of long-term stable operation in a variety of harsh environments. In addition, Nb bar also has superconducting properties, showing superconductivity at low temperatures, which makes it have a wide range of applications in scientific research and medical equipment. Finally, Columbium rod has good processability and can be made into different shapes and sizes through a variety of processes to meet a variety of engineering needs.
