When choosing niobium rods, you need to consider the following aspects:
1. Purpose: According to the specific purpose of the niobium rod, choose the corresponding product type. For example, if it is used to manufacture high-temperature furnaces, you need to choose niobium rods with excellent high-temperature performance; if it is used to manufacture electronic devices, you need to choose niobium rods with excellent electrical conductivity and thermal conductivity.
2. Purity: The purity of niobium rods has a great influence on performance and service life. High-purity niobium rods have better mechanical properties and longer service life. Therefore, when choosing niobium rods, you need to choose high-purity products.
3. Size: You need to choose the appropriate size according to actual needs. If you need a small-sized niobium rod, you can choose a product of the corresponding size.
